[U-Boot] [PATCH] Default to HOSTARCH if ARCH isn't specified
by Kumar Gala 20 Apr '09

20 Apr '09

Its possible to build natively on several platforms so we might not explicitly set ARCH but detect it via HOSTARCH. As such there are some things that expect ARCH to be set to work correctly.

Done Erasing old environment... Done Writing environment to /dev/mtd1... CRC write error on /dev/mtd1: Invalid argument Error: can't write fw_env to flash ~ # can anyone help me to clear this problem? Regards, B.V.Srikanth Reddy
