[U-Boot-Users] Problems with usb storage devices on MPC5200 / TQM5200

[Martin Krause]

Hi,

with the current U-Boot (top of tree) I'm not able to access an USB
memory stick on a MPC5200 based TQM5200 board. The 'usb start' 
command prints some error messages:

In the current TQM5200 configuration the generic OHCI driver is used

Has anyone observed similar problems with the generic OHCI driver?

Can you confirm that it worked before with the generic driver and the
same stick? Only few usb related changes were merged recently, so it if
it did break, it shouldn't be hard to identify the culprit.

I have to admit, that I never tested the TQM5200 (nor any other 
MPC5200 board) with the generic OHCI driver before. So I could not
tell, if it worked ever with the generic driver.

For the test with the current U-Boot I used three different memory
sticks, which always worked with the old cpu specific OHCI driver.
None of it worked with the generic driver :(.

Martin Krause

We tested it, of course - with the hardware that is available to us.

Which means on pre-Rev. B CPU only. [I wish TQ would finally
understand what it means NOT to provide current hardware.]

I guess you use Rev. B silicon? Could you please try it on an old
board?

I think I tested it on both versions. But I'm not sure. I will
repeat the test on an old board.

I repeated the test with an old TQM5200 board (v1.2 MPC5200 cpu).
Unfortunately with the same results. USB sticks are not working:

I repeated the test with some older U-Boot versions (with the
generic OHCI driver), but on neither USB sticks are working :(

[Markus Klotzbücher]

Hi Martin,

I finally got around to look into this. It was tested and worked with
earlier U-Boot versions until some time ago I made big endian OHCI
controllers a CFG_ option. With this option added to the TQM5200
config, USB work fine again.

Sorry, don't know how I missed this.

Attached patch fixes this.

Best regards

Markus Klotzb?cher



The MPC5200 OHCI controller operates in big endian, so
CFG_OHCI_BE_CONTROLLER must be defined for it to work properly.

Thanks for fishing out the reason!

At the moment I'm a bit short of time (who not?). I`ll test
the patch next year ;-)

Today I found some time to test your patch on the TQM5200 and
TQM5200B. I tested with several USB-Sticks. Everything works
fine. Thanks!

Hi

I'm not sure whether that's the same problem but with my u-boot (a bit 
older though) the usb stuff works with sticks <= 256MB only! I tried 
several sticks of size >= 512MB and they don't work. BTW my hardware is 
TQM5200 based (pre B) also.

Maybe that explains why it worked for denx but not for TQ.

I used Sticks <= 256 MiB for testing.

Hm, I'm skeptic. Do you know wich OHCI driver is used in your
U-Boot? The newer generic one or the older mpc52xx specific?
IFAIK the generic one is used since U-Boot v1.3.0-rc3. I only had
problems with the generic one. No stick I tested does work with
this driver - but I haven't tested sticks >= 512 MiB, though.

Martin Krause

You are right, the problem with >=512MB sticks exists on u-boot version 
1.2.0 and it uses the older mpc52xx specific ohci driver. Actually this 
is not a problem for me!

I think the problem is on the FAT.
Did you check?
