LPC1833 download error

[9218sky]

1.  ULINK is good, LED blink code download to my board run successful

2.  I add disable peripheral clock, when download the code to my board, not run!

     cancel disable peripheral clock code, build and download to my board again,  MDK clue on  JTAGE cable error!

    but download other project to other board,  as run good. so ulink and cable is good.

3. MCU start safeguard mode? other one?

disable peripheral clock function source as follows:

void PerClk_Config(void) {
Chip_Clock_Disable(CLK_APB3_I2C1); 
Chip_Clock_Disable(CLK_APB3_DAC);

return;
}

purpose: LPC1833 power expend testing

problem: download to target board, not run.  and cannot download again. I don't  why? how do came back?

You have obviously disabled too much. To recover your part, read this FAQ
