Updating u-boot

npl

Hello,

I cant stop u-boot from loading Ubuntu, entering keys on the debug uart wont do anything. Thus I downloaded u-boot sources, compiled and configured it.

I used the following commands:

1. git clone git://git.denx.de/u-boot.git
   
2. cd u-boot
   
3. make rk3288_config
   
4. 
   
5. CROSS_COMPILE=/opt/toolchain/bin/arm-none-eabi- make

Copy the code

This got me u-boot.bin, u-boot.img, u-boot-dtb.bin and u-boot-dtb.img. Not the RK3288Loader_uboot_Vx.xx.xx.bin file thats mentioned there: http://wiki.t-firefly.com/index.php/Firefly-RK3288/Uboot/en

Do I need anther repositore/branch or should I use u-boot.img ? If the u-boot is damaged can I still fix it with the tools?

Hmm, this board seems pretty dead.

To answer my own question: The sources are from some forks of u-boot, as far as I know including some binary blobs. http://linux-rockchip.info/mw/index.php?title=Boot_Sequences.

I could`nt update the loader (u-boot) because the instructions are wrong (the only tool working seems to be Linux_Upgrade_Tool_v1.21), and it would`nt enter command prompt unless I would set the bootmode to Android.

Now the hacking can commence.

The U-Boot source code of Firefly-RK3288 is included in the SDK.

AFAIK, git://git.denx.de/u-boot.git has the rough RK3288 mainline support.
