I understand that your board is neither a rpxlite nor a TQM8xxL - so which board are you using then? > init_rpxlite_mtd: chip probing count 0 > request_module[cfi_cmdset_0002]: Root fs not mounted > Support for command set 0002 not present ... > RPXLITE: No support flash chips found! Seems you misconfigured your MTD sub-system, like selection CFI support when you board in fact does not use CFI conformant flash chips. Or your board does not find the correct start address of the flash memory - which in case of the TQM8xxL gets passed in the bd_info structure by U-Boot. > Where is wrong? and when I use the commmand xd ,show no command,why? Please explain where "xd" comes into play?
