U-Boot loader for Olimex A20 SOM EVB.
|
|
|
|
To install this bootloader on an sdcard just do :
|
|
dd if=/usr/local/share/u-boot/u-boot-boardname/u-boot-sunxi-with-spl.bin of=/path/to/sdcarddevice bs=1k seek=8 conv=notrunc,sync
|
|
|
|
This version is patched so that:
|
|
* ELF and API features are enabled.
|
|
* The default environment is trimmed to just what's needed to boot.
|
|
* The saveenv command writes to the file u-boot.env on the FAT partition.
|
|
* The DTB file name is chosen based on the board model and passed to ubldr.bin
|
|
using the fdtfile env variable. ubldr.bin loads the DTB from /boot/dtb/ on
|
|
the FreeBSD partition.
|
|
* By default, it loads PIE ubldr.bin from file ubldr.bin on the FAT partition
|
|
to address 0x42000000, and launches it.
