atmega1281上的avrdude错误

Question

我有atmega1281和AD-USBISP V03.6

我有编译问题写在闪存上

问题是

sudo avrdude -p m1281 -P /dev/ttyUSB0 -c stk500v2 -U flash:w:test.hex:i
avrdude: stk500v2_ReceiveMessage(): timeout 
avrdude: AVR device initialized and ready to accept instructions
Reading | ################################################## | 100% 0.01s
avrdude: Device signature = 0xffffff (retrying)
Reading | ################################################## | 100% 0.01s
avrdude: Device signature = 0xffffff (retrying)
Reading | ################################################## | 100% 0.01s
avrdude: Device signature = 0xffffff
avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.
avrdude done.  Thank you.

我猜想的第一个问题是stk500v2_ReceiveMessage(): timeout

但是我不知道如何解决这个问题。

如何解决这个问题，把test.hex写在avr的flash上？

Answer 1

您可以使用-c选项选择编程器类型，对于USBISP使用-c usbasb。因此，请尝试以下操作

sudo avrdude -p m1281 -P /dev/ttyUSB0 -c usbasb -U flash:w:test.hex:i

如果失败，请添加另一个选项-B 10来设置时钟

sudo avrdude -p m1281 -P /dev/ttyUSB0 -B 10 -c usbasb -U flash:w:test.hex:i
