Bootloader not working

Postby radek » Thu Sep 02, 2010 5:46 pm

I need to put standard Boarduino bootlader into new chips. These are ATmega328P.
I build ISP from one working 328P, attached it to Boarduino with blank chip and burn with:

make TARGET=adaboot328 isp328

that command I found on http://www.ladyada.net/library/arduino/bootloader.html.

Result is. I'm able to burn bootloader. It also flashes red LED when reset. But I'm not abble to use it. Trying to burn some sketch from Arduino IDE, I got
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

Programming through the ISP connector can be done. I burn a sketch which actively use serial console to test the serial connection. It runs. But the bootloader does not. I try to modify the bootloader. I change the number of flasshes after reset. Well it flashes as much as I changed in source. But I'm still not able to program via serial.

Under the same condition, the original 328P from Adafruit works great.

Problem solved.
I just get another bootloader from http://www.wulfden.org/TheShoppe/freedu ... BOOT.shtml
And now it burns nice.
