LPC54114 bricked after wrong clock configuration

[nasser_molaei]

Hi guys,

We have several boards with LPC54114J256UK49 that are bricked.

We programmed those using MCUExpressoIDE and PEMicro, and for some reason the clock configuration was not setup properly in that version of firmware. All MCUs halt after reboot and we are UNABLE to reprogram them. We can NOT erase either.

The question is, are those now-bricked MCUs recoverable, if so how?

We also have Keil and a ULinkPro in hand.

Many thanks.
