Hi, Gentleman.

I want to make program to  write data on the flash memory.

I refer the sample program in mspm0_sdk "flashctl_multiple_size_write", and add the "over-write different data program" on the same flash memory address.

This program shall write 8bit data 0x11, 0x03, 0xff on the flash memory 0x00010000, but it doesn't change after 1st byte '0x11' is written. (I expected memory data will change 11->03->ff)

How can I write program that I want. Please advice me.
