Hi,
I was booting barebox from git on my "openmoko" gta04 today but what was
not working was the mmc initialization.
It was failing in mmc_init_setup() in ./drivers/mci/omap_hsmmc.c after
printing "timedout waiting for cc2!" when I had DEBUG enabled.
-%<-----------------------------------------------------------------
barebox 2011.10.0-00107-gdac6e90-dirty (Oct 24 2011 - 22:12:10)
Board: Texas Instrument's Beagle
omap-hsmmc@omap-hsmmc0: timedout waiting for cc2!
Cannot reset the SD/MMC interface
->%-----------------------------------------------------------------
The gta04 should be very similar to the beagleboard and hence I was
building using the omap3530_beagle_defconfig.
any hints on how to continue debugging this problem are highly
appreciated!
cheers, josch
PS: sorry for my previous mail which was the result of hitting "y"
instead of "e" in my mutt...

You could start barebox from U-Boot (just load the barebox binary image
to RAM and jump to it using the U-Boot 'go' command). Then you could
comment out the lowlevel code from barebox (arch_init_lowlevel, pin_mux)
and see if the problem persists. Maybe there is something different in
the lowlevel code.
Another thing: Where does this string come from? We have this twice in
the driver and one of them should really be "timeout waiting for reset
done"

This is a great idea! So first I loaded the unmodified barebox binary
using:
mmc rescan 0
fatload mmc 0 0x82000000 barebox.bin
go 0x82000000
It started executing and the error was the same as before.
Then I tried doing what you suggested above and commented
arch_init_lowlevel in ./arch/arm/mach-omap/omap3_core.S and I was not
sure what you meant by `pin_mux` as the string appeared nowhere in the
code but I thought you might mean the mux_config in
./arch/arm/boards/omap/board-beagle.c ? But after doing that, barebox
would just not start anymore when loaded by uboot.
So can you give me some more specific advices on what to comment?

If I read the code correctly, then my error comes from line
224 of ./drivers/mci/omap_hsmmc.c :
dev_dbg(hsmmc->dev, "timedout waiting for cc2!\n");
I activated this debug message by using "#define DEBUG" on top of the
file. Initially I only got the message "Cannot reset the SD/MMC
interface" from line 1185 in ./drivers/mci/mci-core.c after it tried to
call the init code from omap_hsmmc.c.
But where would you find "timeout waiting for reset done"? I tried to
recursively grep my barebox sources without finding this string?
thanks!
cheers, josch

Yes, that's what I meant

Strange. Should not be the case, no idea what's happening here.

Look again, we accidently have the same string twice in the driver:
./drivers/mci/omap_hsmmc.c:201: dev_dbg(hsmmc->dev, "timedout waiting for cc2!\n");
./drivers/mci/omap_hsmmc.c:224: dev_dbg(hsmmc->dev, "timedout waiting for cc2!\n");
The one in line 224 should really be "timeout waiting for reset done".
So what I wanted to know is whether it's the error message in line 201
or 224 that we see. So please change one of them

I changed both, appending the string of the function calling them
(mmc_init_stream and mmc_init_setup)
when booting I get:
barebox 2011.10.0-00107-gdac6e90-dirty (Oct 25 2011 - 12:00:54)
Board: Texas Instrument's Beagle
omap-hsmmc@omap-hsmmc0: timedout waiting for cc2! (in mmc_init_setup)
Cannot reset the SD/MMC interface
So this is where it comes from.
cheers, josch

Does barebox now work on your gtk04? If not, I'd be willing to help with
the port, but somebody would have to organze a hardware for us in that
case.

nope, I'm relying on input from you guys ;)

if there are no leftover units in munich and you are located in germany
i could lend you mine for one or two weeks?

We are located in Germany (see signature). However, the variant with the
leftover units would be preferred :-)
