eMMC broken on SK-AM62

eMMC broken on SK-AM62

Hi Nishanth,

I've been trying for the last few days to get an SK-AM62 to boot from
the eMMC user data area.

I finally got the jumper configuration to make the CPU boot from there
thanks to Mattijs, but it looks like the 2024.01-rc2 release doesn't
support booting from there:

U-Boot SPL 2024.01-rc2 (Nov 08 2023 - 14:11:12 +0100)
SYSFW ABI: 3.1 (firmware rev 0x0009 '9.1.5--v09.01.05 (Kool Koala)')
SPL initial stack usage: 13368 bytes
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

It looks like you tried to fix it with 0f1c1e8b368b ("arm: mach-k3:
am625: Add support for UDA FS"), but it looks like it's not enough.

Thanks!
Maxime

I confirm I reproduce the issue on AM62x SK EVM.

Beagle play seems to boot fine:

Press SPACE to abort autoboot in 2 seconds

Note that Beagle Play does not boot tiboot3 from UDA (User Data Area)
but from mmc0boot0 so the boot flow is not exactly the same.

There is nothing complex here - sorry for the late response, Sync DT
with v6.7-rc1 should take care of this:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm64/boot/dts/ti?id=c412c2f26eed08b1836ccf79f5547b67c1b55d5d
Vs:
https://github.com/u-boot/u-boot/blob/master/arch/arm/dts/k3-am625-sk-u-boot.dtsi#L93
(notice no sdhci0 with bootph properties)

I backported that linux patch onto 2023.10 and 2024.01-rc2, both work
like a charm.

Thanks!
