[tr]IAR 用JLINK在线调试 STM32F103时出现以下错误Tue Jan 21 21:22:30 2014: Fatal error: Can not read register 15 (R15), CPU may not be halted  ；还出现以下警告Tue Jan 21 21:22:30 2014: The stack 'CSTACK' is filled to 100% (2048 bytes used out of 2048). The warning threshold is set to 90.% 。特别奇怪的是 输出不接负载时，调试一切正常，接上负载后，就出现了上面的警告，搞了两天都没找出具体是什么原因，请各位大侠协助
