avrdude 和 atmega48pa

Question

我可以使用 avrdude 对 atmega48pa 进行编程吗？我的签名有问题...

% avrdude -pm48 -cavrisp2 -Pusb -V -U flash:w:main.hex

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e920a
avrdude: Expected signature for ATMEGA48 is 1E 92 05
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

我已在 /etc 目录中的 avrdude.conf 中添加了一些新行

[...]
part
    id               = "m48pa";
    desc             = "ATMEGA48PA";
     has_debugwire = yes;
     flash_instr   = 0xB6, 0x01, 0x11;
     eeprom_instr  = 0xBD, 0xF2, 0xBD, 0xE1, 0xBB, 0xCF, 0xB4, 0x00,
                     0xBE, 0x01, 0xB6, 0x01, 0xBC, 0x00, 0xBB, 0xBF,
                     0x99, 0xF9, 0xBB, 0xAF;
    stk500_devcode   = 0x59;
    signature        = 0x1e 0x92 0x0a;
[...]

，但现在我收到另一个错误

avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may not be reliable.

问题

有人可以帮助我吗闪存 atmega48pa aith a avrispmkii

Answer 1

只需使用 -F 选项即可覆盖检查。它对我来说编程没有任何问题。这不是最优雅的解决方案，但比无法运行程序要好。

Answer 2

作为参考，这是您在 electronics.stackexchange.com 上提出的问题的链接（带有答案）
基本上

​，正如您所展示的，您可以将芯片配置添加到 /etc/avrdude.conf - 事实上，在您的最后一个示例中它可以正常工作。
