hi
i plan to have a growing list that will be needed from reset (or power off) to reset.
Each entry in list is a byte (could be a word of 4 bytes), as I need it from start up to start up, how and where should I put the new value.
I thought I could write 1 byte to flash at address 0x0c000000 and then to 0x0c000001 (or to 0x0c000004) but all the examples I have show only 256 bytes as minimum.
what is right? wher do i see it in manual?
regards,
Maccabi

Hi,
Are you uisng XMC1000 family device? The minimum size to erase the flash is one page size (256 bytes) and to write data into the flash, the minimum size is one block (16 bytes). Kindly follow the appnote
for sample code.
