因为Keil评估版编译有大小限制的问题，不得不使用其它的IDE，于是使用SEGGER Embedded Studio for ARM，芯片HC32F460KEUA，之前Keil下载更新调试都很正常，但是使用Embedded Studio后开始还可以没什么问题，但是昨天下载后，芯片无法启动，也不能再次下载，报错如下：
- Start of erasing sectors
- CPU could not be halted
- ERROR: Cannot read register 15 (R15) while CPU is running
- ERROR: Cannot read register 16 (XPSR) while CPU is running
- ERROR: Cannot read register 13 (R13) while CPU is running
- ERROR: Timeout while preparing target, core does not stop. (PC = 0x00000000, XPSR = 0x00000000, SP = 0x00000000)!

- End of erasing sectors
- ERROR: Erase failed

更换芯片后，第一次下载可以通过，也可以正常执行，但是断电重启，问题依旧。
然后使用例子efm_simple下载到RAM中执行，程序总是在EFM_SectorErase处跑飞了。
