Details:
avrdude fails to flash some of our hex files. A sample project (without
Nut/OS libs) is available for download:
http://www.ethernut.de/arc/inetq-spduo.zip
avrdude -p atmega2561 -P com2 -c stk500v2 -U flash:w:inetq.hex
fails with
avrdude: verification error, first mismatch at byte 0x10000
0x90 != 0xff
avrdude: verification error; content mismatch
We use the SP Duo Programmer
http://www.ethernut.de/en/isp/spduo.html
AVR Studio works fine.
The inetq-spduo.zip archive contains three hex files:
inetq.hex - the original hex file
image-spduo.hex - image of the failed avrdude programming, read back with
AVR Studio and JTAGICE
image-jtagice.hex - image of correct programming (at least this one runs
fine)
