我可以用 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

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.
我在 /etc -directory 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;

但现在我又遇到了一个错误
avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may not be reliable.

这里有一些带有“-vvv”的调试信息：
