U-Boot versions are a bit tricky. Here we have a collection of tested U-Boots and associated bugs.


Identifying version for a u-boot.bin image

The following command should tell you which version of a U-Boot is contained in a particular image :

$ strings gta02v5_and_up-u-boot.bin  | grep U-Boot

Identifying current boot-loader version

The version is displayed on top of the booloader's menu.

Being connected to it, the version command can also be used.

You can also check current boot-loader version from running openmoko system:

$strings /dev/mtd1 | grep Bootloader

Installing another U-Boot version

See Flashing_the_Neo_FreeRunner#Flashing_the_boot_loader_to_the_NAND for instance.


Tested versions (obsolete)

U-Boot version Comment Hang on boot ttyACM0 flowcontrol Boot from SD
1.2.0-moko9_r0 2007.08 snapshot no hangs a bit buggy crashes
1.2.0-moko9_r8 SH1-included no hangs a bit buggy works
1.2.0-moko9_r13 "good-for-sd-boot" hangs  ? works

GLAMO improvements

A "major" version is available at gena2x's site, read more about it at u-boot-gena2x

As reported in the following thread: http://lists.openmoko.org/pipermail/community/2010-July/062495.html it allows for better performances in the glamo usage.


Hang on boot

Bug #887: U-Boot initialization race condition: Hangs on boot

Booting directly makes the kernel oops, but booting via the menu works.

ttyACM0 flowcontrol

Bug #? (Comment 4 here?)

In the USB U-Boot console, fast input seems to work but fast output is buggy: for example, random parts of printenv go missing.

Boot from SD

Bug #799: data abort while reading from SD Cards

Booting from SD fails. mmcinit works but trying to access the filesystem causes a crash.
