Hello, The U-Boot version I am using is 1.1.2.
I forgot to mention my sector sizes: they are as given in the AT49BV163D data sheet. Sectors up to address 0x0000ffff are 8KB in size, while all others after 0x00010000 are 64KB. And the commands I use are: * tftpboot 20000000 uimage * cp.b 20000000 10020000 fe4bc # my uimage is 0xfe4bc (1041516) bytes, the copy will always fail here I tried to copy in chunks of smaller sectors each but I cannot copy if the range written to crosses the "special" byte 10102000: * cp.b 200e0000 10100000 2000 # works, copies to 0x10100000 - 0x10101fff inclusive * cp.b 200e0000 10100000 2001 # fails, even though it is writing to the same 64KB sector as the previous copy I tried erasing the problematic sector but it appears to be only half erased - everything after 0x10102000 is intact.
