Hi,
I'm trying to boot from usb fel mode on A23. I have rebuilt your sunxi-wip
branch, and try to run on my A23 (q88?) board, but it's failed in fel mode
in executing.
I think the u-boot-spl.bin can be used as A20, this's the website I refer
to:
http://docs.cubieboard.org/tutorials/cb2/development/booting_from_usb_in_fel_mode
my testing instructions are:
fel write address u-boot-spl.bin
fel exec address
the address for A20 is 0x2000, so that the DRAM will be initialized. but
it's incorrect for A23 if the size reach 0x4000.
can you please let me know how to use fel and your u-boot-spl.bin?
I've just tested this, and it works fine for me using the following commands:
make -j4 CROSS_COMPILE=arm-linux-gnu- Ippo_q8h_v1_2_felconfig
Note the _felconfig rather then _defconfig at the end !
And then:
make -j4 CROSS_COMPILE=arm-linux-gnu-
sudo ~hans/bin/fel write 0x2000 spl/u-boot-spl.bin
sudo ~hans/bin/fel exe 0x2000
sleep 0.5
sudo ~hans/bin/fel write 0x4a000000 u-boot.bin
sudo ~hans/bin/fel exe 0x4a000000
Regards,
Hans
