Hi,
I'm using LPC55S28-EVK for test on writing custom data to customer factory page using this function (ffr_cust_factory_page_write()) where seal argument is set to false. After doing so, attempts to re-flash the board no longer possible due to CMSIS-DAP error. Is there any way to restore this board?
Hello,
The board works well with Eclipse/GNU-based tools from NXP and other industry.The board also includes an on-board,CMSIS-DAP compatible debug probe, For more details, please visit our cancellation and returns page.LPC55S69-EVK - LPCXpresso55S69 Development Board mysainsburys.
Thanks for the reply. I set the board to ISP mode by connecting jumper at J10 and P1 and I also connect a serial port to P8. However, I have tried debug with ISP and also using elftosb-gui but nothing happen. No reply is seen from blhost. Is there any instruction on how to fix similar issue like this?
Thanks
Hi
Try if you can debug with ISP mode. If not, refer AN12283 to use elftosu-gui to refresh CMPA. normally this can solve the problem.
Have a nice day

How did you use elftosb-gui refresh CMPA? Could you please send me video or screenshots?
Thanks,
