Please Help...

I have a LPC1768 soldered on my PCB. For the first time, when the device was blank, it was programmed correctly. After that, JLINK cannot connect and program flash.

The error is as below:

Could not power up debug port: Control/Status register reads 00000F03

Failed to connect


I use "J-FLASH ARM V4.34a".

The external clock frequency is 8MHz.

The PLL setting is : M=150 , N=8
