Please test U-Boot Allwinner F1C100s support
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 really have to thank you for reviewing!

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.
Many thanks, Jesse Taube

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

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?

Yes that’s true.

Unfortunately nothing either with SPL

I use PE0 and PE1 Uart0 according to dts.

Anyway I think we’re very close to have it working.

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)?

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

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
