Thanks Ben and all. I really do have 1Gb / 128MB of flash - here's some quick docs:
You're right. Sorry about that.
CHIPSIZE 0x128000 ;The size of one flash chip in bytes
CHIPSIZE 0x8000000
Did you mean to say I should have 'CHIPSIZE 0x8000000' ? Is 0x128000 for 1Gb (128MB) not correct? I tried that but still get the same error.
128 MB = 128 * 1024 * 1024 = 134217728 = 0x8000000
Whenever I use the erase command, I specify the sector size and the number of sectors to erase. Have you tried:
erase 0xf8000000 0x20000 1 (erase 1 sector sized 128kB)
Tried that:
atum8548>erase 0xf8000000 0x20000 1 # Erasing flash memory failed
I think my unlocking is incorrect...
Can you read from the chip using the mdh command? Everything should be
No, I get: atum8548>mdh # SAP: read access failed
Did you try mdh 0xf8000000 ? regards, Ben
