PATCH 1/1 arm: Fix DEBUG_LL for omap zoom2/3

Hi all,

Got a zoom3 finally! This is needed to boot with DEBUG_LL + earlyprintk.

Regards,

Tony

Subject: [PATCH] arm: Fix DEBUG_LL for omap zoom2/3

Zoom2 and 3 have UARTs only on the external debug board. GPMC needs to be mapped early to use it for DEBUG_LL.

Note that with the pending serial.c patches you need to set console=ttyS0,115200n8 as it will be the only UART mapped. To use DEBUG_LL, you need to pass also earlyprintk in cmdline.

One more time. Looks like what I posted is not enough, we also need to make sure the mapping does not overlap with other regions. So basically we can't use 0xfb000000 like we currently have, let's use 0xf7000000 instead unless somebody has better ideas.

On internal TI trees, we do have 0xfa400000 working. Guess that is the magic number.

With this patch[DEBUG_LL + earlyprintk],
I still haven't been able to boot the kernel.
Is it working on your side.

I think you will also need the 3630 serial fixes series posted recently.

I just merged those into omap-fixes-for-linus (and master) branch(es). Maybe give it a try with at commit b3c7740a120c8a7775cb63b4d094466da5c01692 + this patch?

BTW, I'm still seeing mux errors on zoom3, have not yet looked into those.

Great and thanks for pointing out that hole in the mapping.

Here's an updated version of this patch using 0xfa400000. Few other things had to be updated accordingly.

BTW, I'm still seeing mux errors on zoom3, have not yet looked into those.

Looks like we're currently missing these pins. Still need to be checked for GPIO values and modes though, posting just for reference as this fixes the "mux: Unknown ball offset" on 3630.

I think you will also need the 3630 serial fixes series posted recently.
I just merged those into omap-fixes-for-linus (and master) branch(es). Maybe give it a try with at commit b3c7740a120c8a7775cb63b4d094466da5c01692 + this patch?

Thanks, I'll pull in those fixes.
I believe the mux errors are fixed. Have a look at

Patch must have been missed some how.

OK, we really should get fixes like that to mainline kernel ASAP to avoid duplicating the effort.

Then at least one issue remains for zoom3 to be usable.. I'm getting tons of MMC errors trying to mount root on it:

mmcblk1: error -110 transferring data, sector 2097024, nr 8, card status 0x900
end_request: I/O error, dev mmcblk1, sector 2097024
...

Any ideas if that's fixed somewhere also?

Tony

mmc errors (was Re: [PATCH] arm: Fix DEBUG_LL for omap zoom2/3)

Hi Nishant,

The eMMC on Zoom2 has an issue with respect to detection as a high capacity card. This was discussed on the list with Pierre sometime back. I don't have an acceptable solution to make this device work. Rather I prefer to submit a patch which disables MMC2 on these boards.

You can still use MMC1 to mount your file system. This is the card you can plug in to the cage.

Regards,
Madhu

mmc errors (was Re: [PATCH] arm: Fix DEBUG_LL for omap zoom2/3)

Hello all

I've juste finished a modification about a multi eMMC on own platform.
we used 4 eMMC of 32Gib (micron MTFC32GHKD) on same host (MMC1) and we used it like de big device (128Gib)

I had a similar problem (It was the pbias 1 configuration)

I can't test the effect on SD card
any comments...

Madhu, any comments?
Sorry about multiple replies to this mail. Just wanted to avoid top posting.
The eMMC on Zoom2 has an issue with respect to detection as a high capacity card. This was discussed on the list with Pierre sometime back. I don't have an acceptable solution to make this device work. Rather I prefer to submit a patch which disables MMC2 on these boards.
You can still use MMC1 to mount your file system. This is the card you can plug in to the cage.

Madhu

I just merged those into omap-fixes-for-linus (and master) branch(es). Maybe give it a try with at commit b3c7740a120c8a7775cb63b4d094466da5c01692 + this patch?
Thanks, I'll pull in those fixes.
I believe the mux errors are fixed. Have a look at

Tony,

What is the branch on which the kernel is built? I tried the master branch and the omap-fixes-for-linus both does not seem to boot Zoom3.

Hi,

Without doing cherry-pick of above patch url (that Allen mentioned), there's an error when trying to get uart4_[i,f]ck clocks during bootup.

Is this patch being pushed anywhere already? IMHO, at least it should be on omap-testing, but ideally on omap-fixes-for-linus branch.

What do you think?

Regards,
Sergio
