Please test U-Boot Allwinner F1C100s support

Please test U-Boot Allwinner F1C100s support

[Andre Przywara]

Hi,

thanks to the tireless work of Jesse, I think the basic Allwinner
F1C100s support for mainline U-Boot is now ready to be merged. Since I
don't have the hardware, can any of you who have boards please give it a
try on their hardware? I would really love to see some confirmations
before I merge it.
I put a branch here:
https://source.denx.de/u-boot/custodians/u-boot-sunxi/-/tree/f1c100s

This should probably work on any F1C100s board, using the LicheePi Nano
defconfig. Also curious about the F1C200s (looking at you, George ;-)

This is very basic support at this point, there is no USB or SPI
support, and even the SD card is not usable from U-Boot proper. I am
hopeful we can add MMC and SPI support still in this cycle, but I don't
want to hold back this series any longer, and it should be relatively
simple support patches.

What should work though is booting via FEL and from SD card (the SPL
MMC code is in place, if I am not mistaken). Just booting it to a U-Boot
prompt via both methods would be a great test already. Maybe you can
even upload a kernel and initrd via FEL and boot it from there, using
$fdtcontroladdr for the DT address, for instance.

Any replies would be highly appreciated!

Many thanks,
Andre

I have tested on both. Giulio has them aswell now.

Sd card will work if we add it to the dts.

I have patches for both spi-boot and U-Boot proper spi suport.
I did manage to get it to find the boot device with:
`u32 brom_call = *(u32*)(fel_stash.sp-4);` in mach-sunxi/board.c with 
the suggestion that Stephen said. Should I submit after it gets into 
master or is tomorrow fine.

Hi Andre and Jesse,

I test it today on both F1C100s and F1C200s!
Lichee Pi Nano and the Jesse’s board with F1C200s.

Re: Please test U-Boot Allwinner F1C100s support

[Giulio Benetti]

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.

Am I doing something wrong?

Best regards

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?
Do you see UART output from the SPL, or nothing at all?
And you are not using UART0 on the PortF pins, so multiplexed with the
MMC, I guess?

Cheers,
Andre

Yes that’s true.

Unfortunately nothing either with SPL

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 :-)?

That is interesting. If there would be a problem with the MMC code, you
should at least see the SPL banner, and then see it failing loading U-Boot
proper. I take it FEL boot works? Maybe we miss something with the clock
setup that the BROM does for us during FEL operation?

Can you try to clear the area between the end of the SPL and the beginning
of the U-Boot proper image (dd if=/dev/zero of=/dev/sdX bs=1k seek=32
count=8)?
Does any other branch work with SD card booting? Can you check the SPL
size in there (with hexdump -C u-boot-sunxi-with-spl.bin | head, check for
the halfword at 0x10)?

That's the problem: I am driving blindfolded, because I don't have
hardware :-(

Yes, it does work on both F1C100s and 200s boards :-/

Yes, it sounds like that, it's a classic

I've zeroed the first 32MB of sd-card now, so we're sure nothing can 
interfere.

# sudo dd if=/dev/zero of=/dev/sda bs=1M count=32
# sync
# sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sda bs=1k seek=8
# sync

(/dev/sda is my sd-card for real since I have m.2 ssd)

Yeah, but I've read you've ordered it! :-)

Jesse has it working so maybe he can check how clocks are setup after 
BROM using u-boot itself. I've never understood why Allwinner/Rockchip 
place jtag on the sd-card pins. I really hate it, it would take so few 
with free jtag pins to check this :-/

Sorry, I meant to clear those bits after writing to the card (or clear that
in the image file). binman now manages the packaging, so places 0xff into
the 8K gap between our 24K SPL and the 32KB offset we place U-Boot proper
at. If the BROM would read beyond the 24KB, the checksum would fail,
but zeros are ignored by the algorithm, so we are a bit more robust. Also
it might be interesting to set the size of 32KB (fixing up the checksum).
What I was after is that no output could also mean that the BROM dismissed
the SPL it found on the SD card. Do you see FEL mode enabled afterwards?

I've tested succesfully on both F1C100s and 200s boards!
https://source.denx.de/u-boot/custodians/u-boot-sunxi/-/tree/f1c100s

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
