1.1 SMART MULTIPORT BOARD DRIVER
|
||||
|
||||
This driver supports the EasyIO and EasyConnection 8/32 range of boards.
|
||||
All of these boards are not classical intelligent multiport boards, but are
|
||||
host based multiport boards that use high performance Cirrus Logic CL-CD1400
|
||||
RISC UART's (they have built in FIFO's, automatic flow control, and some
|
||||
other good stuff).

|
||||
UART's (they have built in FIFO's, automatic flow control and some other
|
||||
good stuff).
|
||||
|
||||
The EasyIO range of cards comes in 3 forms, the EasyIO-4, EasyIO-8 and the
|
||||
EasyIO-8M. All of these are non-expandable, low cost, ISA, multiport boards
|
||||
with 4, 8 and 8 RS-232C ports respectively. Each EasyIO board requires 8
|
||||
bytes of IO address space and 1 interrupt. On an EISA system it is possible
|
||||
bytes of I/O address space and 1 interrupt. On an EISA system it is possible
|
||||
to share 1 interrupt between multiple boards. The EasyIO-4 has 10 pin RJ
|
||||
connectors, and the EasyIO-8 comes with a dongle cable that can be either
|
||||
10 pin RJ connectors or DB-25 connectors. The EasyIO-8M has 6 pin RJ
|
||||
connectors.
|
||||
connectors, and the EasyIO-8 comes with a dongle cable with either 10 pin RJ
|
||||
connectors or DB-25 connectors. The EasyIO-8M has 6 pin RJ connectors.
|
||||
|
||||
The EasyConnection 8/32 family of boards is a relatively low cost modular
|
||||
range of multiport serial boards. The EasyConnection 8/32 boards can be
|
||||
configured to have from 8 to 32 serial ports by plugging in external serial
|
||||
port modules that contain from 8 to 16 ports each. There is a wide range of
|
||||
external modules available that offer: DB-25 connectors, RJ-45 connectors
|
||||
(both with RS-232 D and E compatible drivers), and also RS-422 ports. The
|
||||
EasyConnection 8/32 boards come in ISA and MCA bus versions. The board takes
|
||||
the form of a host adapter card, with an external connector cable that plugs
|
||||
into the external modules. The external modules just clip together to add
|
||||
ports (BTW they are not hot pluggable). Each EasyConnection 8/32 board
|
||||
requires 2 separate IO address ranges, one 2 bytes in size and a secondary
|
||||
region of 32 bytes. Each board also requires 1 interrupt, on EISA systems
|
||||
multiple boards can share 1 interrupt. The secondary IO range (the 32 byte
|
||||

|
||||

|
||||
ports. The EasyConnection 8/32 boards come in ISA, PCI and MCA bus versions.

|
||||
EasyConnection 8/32 board requires two separate I/O address ranges, one two
|

|
||||
8/32 requires two regions of I/O address space, normally these will be
|
||||
automatically allocated by the system BIOS at system power on time. Each MCA
|
||||
EasyConnection board requires one I/O address region 64 bytes in size. All
|
||||
board types also require one interrupt. On EISA systems multiple boards can
|
||||
share one interrupt. The secondary I/O range of the ISA board (the 32 byte
|
||||
range) can be shared between multiple boards on any bus type.
|
||||
|
||||
So thats the hardware supported (sounds like a marketing spiel doesn't it!).
|
||||
I am working on drivers for other boards in the Stallion range, so look
|
||||
out for those some time soon...
|
||||
|
||||
1.2 INTELLIGENT MULTIPORT BOARD DRIVER
|
||||
|
||||
This driver is for Stallion's range of true intelligent multiport boards.
|
||||
It supports the EasyConnection 8/64, ONboard, Brumby and original Stallion
|
||||
families of multiport boards. The EasyConnection 8/64 and ONboard boards come
|
||||
in ISA, EISA and Microchannel bus versions. The Brumby and Stallion boards
|
||||
are only available in ISA versions.
|
||||
|
||||
The EasyConnection 8/64 family of boards is a medium cost, high performance,
|
||||
modular range of intelligent multiport serial boards. The EasyConnection 8/64
|
||||
boards can be configured to have from 8 to 64 serial ports by plugging in
|
||||
external serial port modules that contain either 8 or 16 ports each (these
|
||||
modules are the same used by the EasyConnection 8/32 board). There is a wide
|
||||
range of external modules available that offer: DB-25 connectors, RJ-45
|
||||
connectors (both with RS-232 D and E compatible drivers), and also RS-422 and
|
||||
RS-485 ports. The board takes the form of a host adapter card, with an external
|
||||
connector cable that plugs into the external modules. The external modules
|
||||
just clip together to add ports (BTW, they are NOT hot pluggable). Each
|
||||
EasyConnection 8/64 board requires 4 bytes of I/O address space and a region
|
||||
of memory space. The size of the memory region required depends on the exact
|
||||
board type. The EISA version requires 64 Kbytes of address space (that can
|
||||
reside anywhere in the 4 Gigabyte physical address space). The ISA and MCA
|
||||
boards require 4 Kbytes of address space (which must reside in the lower
|
||||
1 Mbyte of physical address space - typically in the c8000 to e0000 range).
|
||||
No interrupts are required. The physical memory region of multiple
|
||||
EasyConnection 8/64 boards can be shared, but each board must have a separate
|
||||
I/O address space.
|
||||
|
||||
The ONboard family of boards are traditional intelligent multiport serial
|
||||
boards. They are Stallion's older range of boards with a limited expansion
|
||||
capability. They come in 4, 8, 12, 16 and 32 port versions. The board uses
|
||||
the same base card (which has 4 ports on it) and is expanded to more ports
|
||||
via a mezzanine board that attaches directly onto the board. External panels
|
||||
plug into the ONboard providing RS-232C ports with DB-25 plugs. An RS-422
|
||||
DB-25 dual interface panel is also available. The ISA and microchannel
|
||||
ONboards require 16 bytes of I/O address space and 64K bytes of memory
|
||||
space. The memory space can be anywhere in the 16 Mbyte ISA bus address
|
||||
range. No interrupt is required. The EISA ONboard requires 64 Kbytes of
|
||||
memory space that can be anywhere in the 4 Gigabyte physical address space.
|
||||
All ONboard boards can share their memory region with other ONboards (or
|
||||
EasyConnection 8/64 boards).
|
||||
|
||||
The Brumby family of boards are traditional, low cost intelligent multiport
|
||||
serial boards. They are non-expandable and come in 4, 8 and 16 port versions.
|
||||
They are only available for the ISA bus. The serial ports are all on DB-25
|
||||
"dongle" cables that attach to the rear of the board. Each Brumby board
|
||||
requires 16 bytes of I/O address space and 16 Kbytes of memory space. No
|
||||
interrupts are required.
|
||||
|
||||
The original Stallion boards are old. They went out of production some years
|
||||
back. They offer limited expandability and are available in 8 or 16 port
|
||||
configurations. An external panel houses 16 RS-232C ports with DB-9
|
||||
connectors. They require 16 bytes of I/O address space, and either 64K or
|
||||
128K of memory space. No interrupt is required. I will not actively support
|
||||
these boards, although they will work with the driver.
|
||||
|
||||
That's the boards supported by the second driver. The ONboard, Brumby and
|
||||
Stallion boards are Stallion's older range of intelligent multiports - so
|
||||
there are lots of them around. They only support a maximum baud rate of
|
||||
38400. The EasyConnection 8/64 is a true high performance intelligent
|
||||
multiport board, having much greater throughput than any of Stallion's
|
||||
older boards. It also supports speeds up to 115200 baud.

Once you have a new kernel built reboot to start it up. On startup the

Stallion board probes will report on whether the boards were found or not.
|
||||
For each board found the driver will print out the type of board found,
|
||||
and how many panels and ports it has.
|
||||
|
||||
If a board is not found by the driver but is actually in the system then the
|
||||
most likely problem is that the IO address is wrong. The easiest thing to do
|
||||
is change the DIP switches on the board to the desired address and reboot.

do is change the DIP switches on the board to the desired address and reboot.
|
||||
|
||||
On EasyIO and EasyConnection 8/32 boards the IRQ is software programmable,
|
||||
so if there is a conflict you may need to change the IRQ used for a board in
|
||||
the MYKERNEL configuration file and rebuild the kernel.
|
||||
|
||||
Note that the secondary IO address of the EasyConnection 8/32 boards is hard
|
||||
wired into the stallion.c driver code. It is currently set to IO address
|
||||
coded into the stallion.c driver code. It is currently set to IO address
|
||||
0x280. If you need to use a different address then you will need to edit this
|
||||
file and change the variable named stl_ioshared.
|
||||
|
||||
On intelligent boards it is possible that the board shared memory region is
|
||||
clashing with that of some other device. Check for this and change the device
|
||||
or kernel configuration as required.
|
||||
|
||||
|
||||
2.2 INTELLIGENT DRIVER OPERATION
|
||||
|
||||
The intelligent boards also need to have their "firmware" code downloaded
|
||||
to them. This is done via a user level application supplied in the driver
|
||||
package called "stlload". Compile this program where ever you dropped the
|
||||
package files, by typing "make". In its simplest form you can then type
|
||||
./stlload -i cdk.sys
|
||||
in this directory and that will download board 0 (assuming board 0 is an
|
||||
EasyConnection 8/64 board). To download to an ONboard, Brumby or Stallion do:
|
||||
./stlload -i 2681.sys
|
||||
|
||||
Normally you would want all boards to be downloaded as part of the standard
|
||||
system startup. To achieve this, add one of the lines above into the
|
||||
/etc/rc.serial file. To download each board just add the "-b <brd-number>"
|
||||
option to the line. You will need to download code for every board. You should
|
||||
probably move the stlload program into a system directory, such as /usr/sbin.
|
||||
Also, the default location of the cdk.sys image file in the stlload
|
||||
down-loader is /usr/lib/stallion. Create that directory and put the cdk.sys
|
||||
and 2681.sys files in it. (It's a convenient place to put them anyway). As an
|
||||
example your /etc/rc.serial file might have the following lines added to it
|
||||
(if you had 3 boards):
|
||||
/usr/sbin/stlload -b 0 -i /usr/lib/stallion/cdk.sys
|
||||
/usr/sbin/stlload -b 1 -i /usr/lib/stallion/2681.sys
|
||||
/usr/sbin/stlload -b 2 -i /usr/lib/stallion/2681.sys
|
||||
|
||||
The image files cdk.sys and 2681.sys are specific to the board types. The
|
||||
cdk.sys will only function correctly on an EasyConnection 8/64 board. Similarly
|
||||
the 2681.sys image will only operate on ONboard, Brumby and Stallion boards.
|
||||
If you load the wrong image file into a board it will fail to start up, and
|
||||
of course the ports will not be operational!

|

|
||||
in it. Please email me any feedback on bugs, problems, or even good
|
||||
experiences with this driver!

Be aware that these drivers are still very new, so there is sure to be some
|
||||
bugs in them. Please email me any feedback on bugs, problems, or even good
|
||||
experiences with these drivers!
|
||||
|
||||
I will probably also add LKM support some time soon.
|
||||
You can use both drivers at once if you have a mix of board types installed
|
||||
in a system. However to do this you will need to change the major number used
|
||||
by one of the drivers. Currently both drivers use default major number 72 for
|
||||
their devices. Change one driver to use some other major number (how this is
|
||||
achieved will depend on the kernel version you are using), and then modify the
|
||||
mkdevnods script to make device nodes based on those new major numbers. For
|
||||
example, you could change the stallion.c driver to use major number 73. You
|
||||
will also need to create device nodes with different names for the ports, for
|
||||
eg ttyFXXX.
|
||||
|
||||
Currently the intelligent board driver (istallion.c) does not have the
|
||||
ability to share a boards memory region with other boards (you can only do
|
||||
this on EasyConnection 8/64 and ONboards normally anyway). It also does
|
||||
not currently support any memory address ranges above the low 1Mb region.
|
||||
These will be fixed in a future release of the driver.
|
||||
|
||||
Finding a free physical memory address range can be a problem. The older
|
||||
boards like the Stallion and ONboard need large areas (64K or even 128K), so
|
||||
they can be very difficult to get into a system. If you have 16 Mb of RAM
|
||||
then you have no choice but to put them somewhere in the 640K -> 1Mb range.
|
||||
ONboards require 64K, so typically 0xd0000 is good, or 0xe0000 on some
|
||||
systems. If you have an original Stallion board, "V4.0" or Rev.O, then you
|
||||
need a 64K memory address space, so again 0xd0000 and 0xe0000 are good. Older
|
||||
Stallion boards are a much bigger problem. They need 128K of address space and
|
||||
must be on a 128K boundary. If you don't have a VGA card then 0xc0000 might be
|
||||
usable - there is really no other place you can put them below 1Mb.
|
||||
|
||||
Both the ONboard and old Stallion boards can use higher memory addresses as
|
||||
well, but you must have less than 16Mb of RAM to be able to use them. Usual
|
||||
high memory addresses used include 0xec0000 and 0xf00000.
|
||||
|
||||
The Brumby boards only require 16Kb of address space, so you can usually
|
||||
squeeze them in somewhere. Common addresses are 0xc8000, 0xcc000, or in
|
||||
the 0xd0000 range. EasyConnection 8/64 boards are even better, they only
|
||||
require 4Kb of address space, again usually 0xc8000, 0xcc000 or 0xd0000
|
||||
are good.
|
||||
|
||||
If you are using an EasyConnection 8/64-EI or ONboard/E then usually the
|
||||
0xd0000 or 0xe0000 ranges are the best options below 1Mb. If neither of
|
||||
them can be used then the high memory support to use the really high address
|
||||
ranges is the best option. Typically the 2Gb range is convenient for them,
|
||||
and gets them well out of the way.
|
||||
|
||||
The ports of the EasyIO-8M board do not have DCD or DTR signals. So these
|
||||
ports cannot be used as real modem devices. Generally when using these
|
||||
ports you should only use the cueX devices.
|
||||
|
||||
There is a new utility in this package that reports statistics on the
|
||||
serial ports. You will need to have the ncurses library installed on your
|
||||
system to build it.
|
||||
|
||||
To build the statistics display program type:
|
||||
make stlstats
|
||||
Once compiled simply run it (you will need to be root) and it will display
|
||||
a port summary for the first board and panel installed. Use the digits to
|
||||
select different board numbers, or 'n' to cycle through the panels on a
|
||||
board. To look at detailed port information then hit 'p', that will display
|
||||
detailed port 0 information. Use the digits and letters 'a' through 'f' to
|
||||
select the different ports (on this board and panel).
