J-Link Failed to get CPU status after 4 retries Retry意思是:J-Link未能获得CPU的状态后重试,重试4
在保证VCAP1和2都接着电容,BOOT0接着地的情况下,确保电源没有问题,接着检查jlink的线有没有接错。 当所有电路和连接没有问题时,观察jtag的灯是否每次插上都是由绿变红,如果由绿变红,说明该换一个一个jtag试…
估计是Jtag被失能了,设置boot脚从RAM启动,之后用Jlink烧写下,但是程序中不要有失能Jtag的操作,也可以先用串口来擦除下芯片。

If I start the debugging process without setting any breakpoints, the program would run and after a while IAR would prompt ' Failed to get CPU status after 4 retries. Retry?'. However, If I set some breakpoints to the program, the program execution would stop at the break...
你如有个预留了串口,那先用串口将芯片擦除。之后用jlink编译试试,一般这样可以保证,芯片的JTAG被占用了,然后再查问题。
In order to debug a hardware called Spectra, I have bought two Jlink EDU mini debuggers. However, I cann't achieve a successful download. The used integrated development environment was IAR Embedded Workbench V8.32.1. Some related documents (e.g., the…
情况二:在情况一中,查看“Interface”下的“JTAG”和“SWD”如果是灰色的,则打开IAR的"Project"--->"Options..."--->“Debugger”--->"Setup"项的“Driver”下拉项是不是“J-Link/J-Trace”,如果不是,则一定要选中“J-Link/J-Trace”。再回到情况一去选择“JTAG”或“SWD”。此时再下载...
