After some investigations I found that the display could be broken (that is unrelated to the not booting issue). Also I tried to find the error about usb when running the RAM version of u-boot. ######### BEGIN console output ################ U-Boot 1.3.2-moko12 (Dec 17 2008 - 00:49:17) I2C: ready DRAM: 128 MB Flash: 2 MB NAND: Bad block table not found for chip 0 Bad block table not found for chip 0 256 MiB Glamo core device ID: 0x3650, Revision 0x0002 USB: S3C2410 USB Deviced mtdparts variable not set, see 'help mtdparts' mtdparts variable not set, see 'help mtdparts' mtdparts variable not set, see 'help mtdparts' mtdparts variable not set, see 'help mtdparts' mtdparts variable not set, see 'help mtdparts' mtdparts variable not set, see 'help mtdparts' ERROR: usbd_device_event_irq(), 613: (00000000,4) NULL device or device->bus undefined instruction pc : [<00000004>] lr : [<33f88bcc>] sp : 33ed8e9c ip : 33f88bcc fp : 34007f3c r10: 34007f60 r9 : 34007f68 r8 : 33edbfdc r7 : 00000004 r6 : 00000000 r5 : 00000003 r4 : 34007d14 r3 : 00000003 r2 : 00000000 r1 : 00000003 r0 : 34007d14 Flags: nzCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... ######### END console output ################ The strange thing is that the first argument ( 00000000 ) means the handler to the device is not initialized. That could mean a problem in the usb module. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
