Hello Team,


We are using LPC54628 chip into few of our industrial products in which we are facing one issue while accessing flash of LPC54628.


Flash Memory was working fine till few days on LPC54628 Module but suddenly first 4 bytes location may be damaged after that and not able to erase first 4 bytes of Flash Memory.


Due to that we are not able to start boot loader and application image into that board. Also, We have faced same issue into 3 to 4 boards as of now in which there is no any specific steps for that. Sometimes, We flashed boot loader image and we got that issue while sometimes we got that issue runtime into development phase.


Please fine attached screen shot with highlighted 4 bytes of LPC54628 Flash Memory.


Let me know if you have any or any clue for this issue or let me know if need any more details regarding this issue.
