Hi,

I would like to report a little bug with avrdude 6.1.

when I write lock byte:

avrdude -p c128 -c usbasp -U lock:w:0xCC

it works fine


but when I read it or verify it, I get:

avrdude -p c128 -c usbasp -U lock:w:0xCC:m

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.03s

avrdude: Device signature = 0x1e9781
avrdude: reading input file "0xCC"
avrdude: writing lock (1 bytes):

Writing |                                                    | 0% 0.00s
***failed;

avrdude: 1 bytes of lock written
avrdude: verifying lock memory against 0xCC:
avrdude: load data lock data from input file 0xCC:
avrdude: input file 0xCC contains 1 bytes
avrdude: reading on-chip lock data:

avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
         0x0c != 0xcc
avrdude: verification error; content mismatch

avrdude: safemode: Fuses OK (E:FF, H:D2, L:FF)

avrdude done.  Thank you.







So lock fuse is correclty written but avrdude can read lock fuse correctly for
part: c128


Best regards,
