烧写程序相关

我写了一个程序烧进HC32F460JEUA后，再次烧写程序就烧不进去了，Jlink那里还能发现器件，我核对过芯片引脚没有占用Jlink相关引脚，如果占用的话，Jilink设置页面应该是发现不了器件的。但是实际下载程序时，感觉器件在一直复位，Jlink输出的信息如下：
* JLink Info: Reset: Core is locked-up, trying to disable WDT.
* JLink Info: Reset: Halt core after reset via DEMCR.VC_CORERESET.
* JLink Info: Reset: Reset device via reset pin
* JLink Info: Reset: VC_CORERESET did not halt CPU. (Debug logic also reset by reset pin?).
* JLink Info: Reset: Reconnecting and manually halting CPU.
* JLink Info: Found SW-DP with ID 0x2BA01477
* JLink Info: DPv0 detected
* JLink Info: AP map detection skipped. Manually configured AP map found.

但是在下载程序的时候，如果我用一根线把NRST引脚置低，还是可以下载进去的，但是这样麻烦，重要的是不能硬件仿真。
