Details:
ISSUE:
avrdude -c arduino-ft232r -p atmega88p -e
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e930f
avrdude: erasing chip
avrdude: Device is not responding to program enable. Check connection.
FIXES in patch:
- main issue: after some instruction (presumably chip erase) the SCK is H,
so in that case, the consequent enter programming mode was of no success
- the timing does not reflect the datasheet of the cpu (20ms!)
Daniel.
