Hi Wu Star,
非常感谢使用NXP产品,很高兴为你提供技术支持!
根据附件,Flash Magic建议你选择较低的波特率连接,你可以先试试,还有可以用逻辑分析仪抓取数据来分析一下问题所在。
Boot ROM是与内部Flash相互独立,且里面的代码是不会被擦除的。
Have a great day,
TIC

这个BOOTLOAD是写在flash里面的,没有写在rom里面,现在还没找到问题,能提供下BOOTLOAD文件我们烧录试下吗?非常感谢!
Hi,
感谢回复。
这款芯片太老了,我们这边找不到相关的资料,建议是你可以通过Flash Magic读取未被擦除过的P89LPC936FDH内的ISP代码,创建一个BIN文件后,在烧录到被擦除的P89LPC936FDH内。
Have a great day,
