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?
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.
