Which version of GCC you are using? I noticed that "usb start" freezes after message "scanning bus for devices..." if I had memory stick connected. I used GCC 4.6.1 that comes with Yocto 1.1. Without stick I did not have any such problems. The board is very similar to M28EVK. With GCC 4.3.4 it works fine. I also tested both compilers on our Atmel AT91SAM9260 based device but I didn't have such problems. Any ideas how to debug this further? I noticed some comments related to GCC in common/usb.c before usb_set_maxpacket_ep function. I also printed out i and ii in usb_set_maxpacket. Results were something that I didn't expect: i: 0, ii: 0 i: 0, ii: 1 i: 4, ii: -30879 i: 4, ii: -30878 -- Veli-Pekka Peltola _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
