Hi,
I have Freescale i.MX25 3-stack development board + debug board attached
to it. I have built barebox-2011.03.0 using
freescale_mx25_3stack_defconfig with some modifications to support NAND
booting (see below). I have used buildroot-2011.02 to create 2.6.38
kernel (CONFIG_MACH_MX25_3DS=y etc.) and rootfs images.
When I boot these images from barebox, dmesg displays the following
error message constantly and USB host port does not work:
mxc-ehci mxc-ehci.1: GetStatus port:1 status cc001020 102 ACK POWER
sig=se0 OCC
hub 1-0:1.0: over-current change on port 1
hub 1-0:1.0: enabling power on all ports
hub 1-0:1.0: state 7 ports 1 chg 0000 evt 0002
If I try to use Freescale RedBoot (mx25_3stack_redboot_TO1_1.bin from
L2.6.31_09.12.00_SDK_images_MX25 package) with the same kernel and
rootfs, USB works. Is there some initialization that is missing from
barebox?
Here is my barebox diff to freescale_mx25_3stack_defconfig:

if you don't need USB in barebox don't enable it. I also have problems with
OTG port under Linux when it's enabled under barebox. I didn't yet found time
to investigate.

Disabling USB in barebox did not help.

Dear developers!
what is the status of the barebox for Atmel? Anyone tested it with any
SAM* devkits?
I see a big potential of barebox, I like it's structure and design and
I'm interested in sam9m10g45ek support.

Yes.

We have Barebox running on the G45 and on several other older AT91SAM9
chips. Note that not all features might be supported, but it boots :-)

It seems that USBH2_PWR signal is not powered. The following patch for
barebox-2011.03.0 seems to work, using it as GPIO:
