Subject: i.MX25 3-stack - over-current change on port 1 - USB host port not working
Date: Wed, 16 Mar 2011 16:26:51 +0200 [thread overview]
Message-ID: <4D80C8AB.4040905@nextfour.com> (raw)
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:
