Hi All,
I've tried several times on both F1C100s and F1C200s, maybe I'm doing
something wrong but it doesn't work :-/
I burn sd-card with:
# sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1k seek=8
I've triple-checked that the file has been written there by dumping the
sd-card and I see it's written at 0x2000, so 8K offset, like the mangoPI
image for example. But no uart output.
I haven't looked in detail what would be needed for the SPL part of the
MMC driver to really work, I just checked that the base addresses are
correct, the pinmux looked alright as well.
The DT nodes are not needed for the SPL, and I don't see other changes
related to MMC in the original series?
Yes that’s true.
Do you see UART output from the SPL, or nothing at all?
Unfortunately nothing either with SPL
And you are not using UART0 on the PortF pins, so multiplexed with the
MMC, I guess?
I use PE0 and PE1 Uart0 according to dts.
Have you got such board to test it?
Or we can wait for Jesse or George.
I’ve used the git you’ve pointed.
Anyway I think we’re very close to have it working.
At least my work “behind the scenes” will be worth, right Jesse :-)?
Yes, I'm sorry there wasn't much mention of you on this patch.
I Just woke up, sorry i couldn't be here earlier, I'll take a look with
Giulio.
I've tested succesfully on both F1C100s and 200s boards!

I've realized with Jesse that here with me I have 3 USB->Serial
converter broken!!! With the 4th it worked and I've checked with scope
that was hidden by garbage on my desk :-)
So it works! Sorry for the noise
Kind regards
