LPC55S69 Placing data at a certain location

greys_mayf — Sun, 24 Apr 2022 13:42:38 GMT

Dear NXP Community,

I am currently working on a program with TrustZone on the LPC55S69. I am trying to have an array loaded into the program as part of .data or .text, but unfortunately I cannot do that without expanding the PROGRAM_FLASH of the secure project and moving the SG_veneer_table. I tried doing this, but I was receiving bus faults. Maybe someone knows how to do this properly.

Otherwise, I would like to know if it is possible to have this array placed on another segment of memory which would accommodate the size of the array.

Best regards
