U-Boot loader for Wandboard Solo, Dual, and Quad.
|
|
|
|
Install the u-boot.imx file onto the boot disk using:
|
|
|
|
dd if=u-boot.imx of=/dev/whatever bs=1k oseek=1 conv=sync
|
|
|
|
The U-Boot built by this port expects the first 1MB of the boot media to
|
|
be reserved for the U-Boot executable and saved environment. The u-boot.imx
|
|
file begins at an offset of 1K from the start of the boot disk. The U-Boot
|
|
environment area begins at an offset of 512K.
|
|
|
|
This version is patched so that:
|
|
* ELF and API features are enabled to support ubldr.
|
|
* A single U-Boot image supports Solo, Dual[lite], and Quad processors.
|
|
* When the selected board has multiple SD or MMC devices available, the
|
|
mmc0 device in U-Boot (and thus the disk0 device in loader(8)) will be
|
|
whichever device U-Boot was loaded from by the ROM bootloader routines.
|
|
|
|
The sources for this port were originally obtained from commit 87f595d1ee
|
|
at https://github.com/TechNexion/U-Boot-edm/ which appears to be a slightly
|
|
modified fork of the stock U-Boot 2013.10 release. As of this writing,
|
|
the changes in this fork have not been rolled back into upstream U-Boot.
