* i.MX25 3-stack - over-current change on port 1 - USB host port not working @ 2011-03-16 14:26 Teemu Peltola 2011-03-17 9:19 ` Eric Bénard 0 siblings, 1 reply; 6+ messages in thread From: Teemu Peltola @ 2011-03-16 14:26 UTC (permalink / raw) To: barebox 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?

We have Barebox running on the G45 and on several other older AT91SAM9 chips.
