I'm running on MVBLM7 board using CONFIG_SYS_HUSH_PARSER.
While working on some scripts using env-variables holding some physical address values I stumbled over this :
my env-variables used :
loadaddr=0x400000 kernel_addr=0xff81000 kernel_len=0x200000
mvBL-M7> erase $kernel_addr +$kernel_len
................................ done Erased 32 sectors
################# -> using variable as source doesn't work. mvBL-M7> cp.b $load_addr $kernel_addr $kernel_len cp - memory copy
Usage: cp [.b, .w, .l] source target count
################# -> using addr as source works fine. mvBL-M7> cp.b 0x400000 $kernel_addr $kernel_len Copy to Flash... done mvBL-M7>
Why does $load_addr not get expanded ? Any ideas ?
Just some ideas: - Mixed up "loadaddr" with "load_addr"? - And do "loadaddr" resp. "load_addr" really exist? - Tried using ${variable}, instead of $variable?
Kind regards, Jens
