[U-Boot] MX6ULEVK does not boot

[Fabio Estevam]

Hi Peng,

Just noticed that mx6ulevk is not booting with latest U-boot:

U-Boot SPL 2016.01-rc1-00078-g736d174 (Nov 19 2015 - 13:45:19)
Trying to boot from MMC
spl: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

I haven't had a chance to investigate/debug this yet.

Could you please take a look?

Regards,

Fabio Estevam

Looks like I cannot boot using my SanDisk micro SD card. I changed the
SD card and now it boots.

I can confirm you this weirdness. It depends on the SD Card, I have seen
the same on a iMX6 Dual. It does not boot with industrial card (Pretec,
1Gb), no problems with "HC" cards of any size (Toshiba, Sandisk, Hama,..).

Stefano

It is interesting that I do not see the problem if I don't use SPL.

For example: on a mx6qsabresd I can boot the SanDisk card without
issues if I boot the mx6qbsabresd_deconfig target (u-boot.imx binary).

However, if I try booting the mx6sabresd_spl_defconfig (SPL +
u-boot.img) the boot fails with the same error as I noticed on the
mx6ul board.

So it seems this is is SPL MMC related problem.

Thanks,

Or the header stuff on the .imx file making things be set that aren't in
the SPL case?  Can you for example use the bad SD card to read from in
U-Boot if you boot off a good card?

Confirmed, I see the same. It looks like that the BootROM can, but SPL
no. I supposed an isseu with the frequency, and I set it in SPL to
25Mhz, but it does not help.

Right, I see the same.

Sorry for this late reply. I missed you mail. I tried in my side
with one sandisk 2GB macro sd card and one sandisk SDHC I 8GB card.

Both boots fine. What card are you using? Also which revision board, RevA B or C?

Peng.

The card I have here that fails to boot is a SanDisk microSD HC I 8GB.

My mx6ulevk is revB. What about yours?

My is revA. I just tried on revB board using one Sandisk 8GB micro SDHC I card,
it boots ok.

In my case even mx6qsabresd fails to boot when I use the Sandisk 8GB
micro SDHC I card and SPL image.

The non-SPL image (u-boot.imx) boots fine though. I haven't had a
chance to investigate this yet.
