Hello,
I have been using avrdude with my STK500 for some time now. Today I wanted
to try the ATtiny11 in high voltage serial programming mode. For this I had
to upgrade avrdude from 5.1 to the latest 5.3.1 (also tried 5.2). Most of
the times the programming failes with the error 'stk500v2_command(): unknown
status 0x81', while after a view tries it often succeeds and then the
software in the microcontroller seems to be running fine. When 5.3.1 did not
work I have also tried 5.2 and tried upgrading my STK500 firmware, both kept
the same error. The flash.hex contains 52 bytes, the command I run is:
avrdude -p t11 -B 10 -c stk500hvsp -P /dev/ttyS0 -e -U flash:w:out/flash.hex
The ATtiny11 is connected into the STK500 and wired according to the manual,
no additional hardware is connected when the chip is being programmed.
What could I be doing wrong or is this a bug in avrdude?
Thanks in advance,
Lourens
