Hi All,

I was trying to write data in SRAM0 with value of 0x55, value has write properly but at location of 0x20002000 value not write. i am not understanding that why its happened ?

Hi,

I have tried to write SRAM0 with the address 0x2000_0000 with a pointer based on MCUXpresso tools, SDK and LPC54628 board, no problem.

AS you can see that I can write 0x2000_0000 with 0x12345678

BTW, note that the high address of SRAM2 is used as stack, pls do not try to overwrite the stack, otherwise, the chip may crash.

Hope it can help you
