Hi All,
There are 3 topics which I would like to cover in this mail:
- Switching over to upstream u-boot for the linux-sunxi project
(...)
Here are some example instructions on how to build upstream u-boot for the Cubietruck:
git clone git://git.denx.de/u-boot.git cd u-boot make -j4 CROSS_COMPILE=arm-linux-gnu- Cubietruck_defconfig # If you want to use an upstream kernel the next steps can be skipped (*) make -j4 CROSS_COMPILE=arm-linux-gnu- menuconfig # select "ARM architecture" -> "Enable workarounds for booting old kernels" # exit & save make -j4 CROSS_COMPILE=arm-linux-gnu- spl/menuconfig # select "ARM architecture" -> "Enable workarounds for booting old kernels" # exit & save # skip to here if you're using an upstream kernel make -j4 CROSS_COMPILE=arm-linux-gnu-
And now you will have a u-boot-sunxi-with-spl.bin to dd to your sdcard as usual.
(...)
So I thought it'd be a good idea to move over to mainline uboot, but it doesn't seem to be working at all on Cubietruck. When applying power to the board, all I get is
U-Boot SPL 2015.01-rc3-00163-gd8bec60 (Dec 21 2014 - 16:43:41) DRAM:Timeout initialising DRAM
resetting ...
U-Boot SPL 2015.01-rc3-00163-gd8bec60 (Dec 21 2014 - 16:43:41) DRAM:Timeout initialising DRAM
resetting ...
...ad infinitum.
The hardware itself is fine, the NAND bootloader runs OK and I used the board with an old uboot-sunxi some days back. Any ideas on what may be going on?
Cheers!
