请教高手,先用一款LPC1754开发程序,用keil uV4开发环境,JLink V8仿真器,最近几次下载程序,总不成功,速率降低也不行,Flash编程时间设的长一点还是不行(设了3000ms)。下面是提示信息,请高手给分析下从哪方面查起。

Erase Done.
Programming Failed!
=========================================================
速度设为SW 2MHz时,Erase都不成功,降为100kHz,Jtag可以Erase,编程还是不成功,降到10Khz,可以编程,Verify又不成功,请问从哪里查起呢?不胜感激! |
