正在用UC3B256的板子开发RS485的过程当中,一开始可以将程序烧进单片机,正常运行,但是突然就不能再烧写程序了。。。
出现如下错误
Connected to JTAGICE mkII version 6.6, 6.6 at USB:0700000024B3.
No device detected. Tried both JTAG and aWire.
Failed to initialize AVR32 aWire mode.
setParameter:
The command was not understood by the JTAGICE mkII unit.
Failed to initialize AVR32 JTAG mode.
Got unknown JTAG ID: 0x0000.
如果是读取单片机信息,有如下错误
Connected to JTAGICE mkII version 6.6, 6.6 at USB:0700000024B3.
The chip is protected. Perform a chiperase command to enable programming.
于是我进行chiperase, 又会有如下错误
Connected to JTAGICE mkII version 6.6, 6.6 at USB:0700000024B3.
JTAG chip erase failed. IR=0x15.
真是奇怪了,之前一直都挺好的。。。突然就不行了,难道是单片机坏掉了?
求解答,哪位大侠知道原因啊。。。非常感谢!!! |
