LPC55S69 EVK - Wire ACK Error during Debug

SrinathVelavan — Thu, 08 Jun 2023 05:28:16 GMT

Hi,

I am getting the following errors while debugging using LPC55S69 EVK. I am running the B2B SPI example from the SDK for testing. Build process clears without any error but I get this error during Debug.

Any solutions? Also is there a way to factory reset the LPC55S69 EVK board like reflashing to factory new settings?

Hi @SrinathVelavan

Could you please try to download led_blinky demo code. Is the problem the same?

Thanks,

Jun Zhang

Hi,

We solved the issue. Just needed to change the Jumper settings on the EVK to ISP mode and the led blinky code compiled and debugged.

Thanks for your help

Thanks for the sharing. Good to know the problem got solved.

If the problem can be resolved by entering ISP mode, the reason should be your onchip application disturbing debug connection. eg, program in low power mode, watchdog reset, etc.

Entering ISP can bypass the running application.
