I didn't have any problems with the (older) ELDK 4.1 gcc compiler.

Hello Stelian and others, I have made some progress here, and I would like to inform you all: But I have a question here: Does USB-storage devices work in U-boot at your place? (e.g. 1GB USB memory stick) I use U-boot 1.3.4-rc1 You're correct, USB support on the AT91SAM9 boards has some unknown issues. I can reproduce the behaviour you're seing easily here. Nicolas Ferre (added in CC:) confirmed the problem too (with both the current U-Boot version and the atmel specific 1.1.5-atmel_1.5 version). But he is very certain that it did work at some time in the past, with some USB storage devices. I have done a lot of debugging/testing etc. and I noticed that binary deliverables of U-boot for the evaluationkit work properly with USB-storage devices on the AT91SAM9261-EK kit. They were all based on U-boot 1.1.3, 1.1.4, 1.1.5 Atmel versions. But, I was not able to get a working version when I build such a code tree myself. I use gcc version 4.2.3 (Sourcery G++ Lite 2008q1-126) An hour ago I got the stupid idea to get an older compiler: gcc version 3.4.2 (release) (CodeSourcery ARM Q3D 2004) And this one delivers a working usb-ohci in u-boot.bin :-)) Even u-boot-1.3.4-rc1 now works with USB-storage devices on these at91sam9261 cores. I also tried GCC 4.1.0, but that one delivered also a broken binary Compiling without optimisation (-Os) resulted in a binary that did not boot at all... (not debugged yet why) So, with GCC 4.2.3 everything in U-boot seems to work, except the USB-OHCI driver... For the USB-OHCI driver we apparantly need a GCC 3.xx compiler. Now, we need to debug why GCC 4.x is a problem... Kind Regards, Remy So it may be a matter of hardware (lo or hi-speed USB storage devices ?), or a matter of timing somewhere in the driver, I do not know. The Linux USB stack works perfectly, so this is not a hardware problem on the AT91SAM9 chip or board. Somebody needs to debug this, but I didn't found the time to investigate yet.

Hello Stelian, You're correct, USB support on the AT91SAM9 boards has some unknown issues. I can reproduce the behaviour you're seing easily here. That is at least some good news. It confirms that I did not introduce this problem myself :-) Nicolas Ferre (added in CC:) confirmed the problem too (with both the current U-Boot version and the atmel specific 1.1.5-atmel_1.5 version). But he is very certain that it did work at some time in the past, with some USB storage devices. I am very certain that it worked on 1.1.5_atmel_1.4 version, with exactly the same USB memory stick as the one that does not work on thecurrent releases... So, I can rule the USB stick as well... So it may be a matter of hardware (lo or hi-speed USB storage devices ?), or a matter of timing somewhere in the driver, I do not know. The Linux USB stack works perfectly, so this is not a hardware problem on the AT91SAM9 chip or board. I agree Somebody needs to debug this, but I didn't found the time to investigate yet. If you badly need it to work, well, you're welcome to try debugging it :) I hoped someone already had a solution, that why I asked you ;-) and yes, it _must_ work here, and I believe I have to dig in this myself. Maybe next week...

[U-Boot-Users] AT91SAM9261-EK USB storage not working...
Hello Stelian, Thank you for adding support for the Atmel AT91SAM9261-EK to U-boot. But I have a question here: Does USB-storage devices work in U-boot at your place? (e.g. 1GB USB memory stick) I use U-boot 1.3.4-rc1 I first ran into this problem on our custom board from which I derived the BSP from your patchset, but I noticed that it does not seem to work either on the AT91SAM9261-EK kit. So, I am curious if I broke something, or if something else fundamental is wrong here... When I do a usb scan, It recognises 2 devices, but when it starts looking for usb-storage devices, it takes a while, and finally it ends up with this error: Device NOT ready Request Sense returned 0 0 0 Kind Regards, Remy - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
