Hi Vishnu,
This patch v2 of series that adds basic support for Allwinner A83T SOC
with
review comments addressed.
Can you provide some quick instructions on how to test this on the
A83T HomletV2 ?
With v1 of these patches I tried to just build them and dd them to
the sdcard, but that did not work.
In the mean time I've figured out that I can get a serial console
with the firmware in the nand using a sdcard breakout board, so
I should be able to enter FEL mode by pressing 2 there, but it would
be really nice if the board would just boot from sdcard...
I broke microsd connector of my A83T board, so boot from microsd not tested.
As you have microSD breakout UART working, you can set
CONFIG_UART0_PORT_F=y and use FEL mode, commands as below
sunxi-fel spl u-boot-sunxi-with-spl.bin
sunxi-fel write 0x4a000000 u-boot-dtb.bin
This is how i have tested it for now.
Ok, that is unfortunate, because regular sd-card boot does not seem to be
working. I think you may be relying on some reset / clocks being enabled by
boot0 before it passes control to the FEL ROM based on you pressing 2
on the serial console. The reason I believe this is that not even the SPL
header is printing, which points to an uart pin / clk / reset setup problem.
I will see if I can get things working with sdcard boot tonight.
Regards,
Hans
