Hi all,
I tried to burn the bootloader to a newly bought ATMEGA168PA-20AU (new version m168 chip), but I encountered a problem saying that:
C:>avrdude -p m168 -c usbtiny
avrdude: AVR device initialized and ready to accept instructio
Reading | ################################################## |
avrdude: Device signature = 0x1e940b
avrdude: Expected signature for ATMEGA168 is 1E 94 06
Double check chip, or use -F to override this check.
It seems that the new m168PA has different signature
I wired the chip with an external 16mhz crystal.
I also tried to modify the fuses in this chip:
avrdude -p m168 -c usbtiny -U lfuse:w:0x1e:m -U hfuse:w:0x94:m -U efuse:w:0x06:m -F
unfortunately, I did a wrong fuse settings (dont know how), and brick the chip.
I was used to burn bootloader for the old version mega168 chip, it worked before.
I am just wondering if anyone has used this atmega168pa-20au chip before? and if so please tell me how do I solve this different signature problem.
Thank you very much.
