申请获得的msp430f6736片子,JTAG就没有通过,可能是多种电源使用不当的原因。请高手看看,谢谢了!
4-Wire JTAG电路如图。请核对电容电阻参数是否正确。
JTAG 8号脚 一定要连接TEST/VPP脚吗? 很多片子根本没有 TEST/VPP脚的。 如果真是这样就麻烦了, 我板子自上没有引出 TEST/VPP脚, 而且片子也焊上了, 晕!
谢谢,经过艰难跳线,像是可以连接了。但新的问题是;Wed Jun 20, 2012 13:37:53: Warning: CPU is OFF (Low Power Mode) and interrupts are disabled! Cannot excute Step/Go. 是片子故障了吗?还是我把多种辅助电源全接上的原故呢?
