Hi André,

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
