I wrote it down because I intended to include it...
I'll check when I get back home but this date looks familiar.
As for reducing the backup: I'm trying to create a backup of the
initial image that came with the device so I'd like to avoid throwing
So the recommendation would be to update the U-Boot with:
1) backup exsitng U-Boot (http://wiki.openmoko.org/wiki/Backup):
Boot NOR boto menu
sudo ./dfu-util -a u-boot -R -U good-u-boot.bin
sudo ./dfu-util -a u-boot_env -R -U good-u-boot_env.bin
2) flash U-Boot
dfu-util -a u-boot -R -D uboot.bin
Reboot the device to use the new U-Boot but the following reminder is
not very clear to me:
"Reminder: You should have boot from NOR first, in order to flash the
boot-loader in NAND. After flashing succesfully, make sure you reboot
from NAND's newly flashed boot loader, to benefit from the updates. "
Does this mean I simply have to reboot the FreeRunner to the NOR boot
menu again, or do I have to boot to the NAND boot menu as
And from which boot menu should I continue backing up the device?
>From the NOR menu?
Which u-boot.bin should I use? And where should I get it?
Thanks in advance.
