LPC1830 lpcopen flashiap sample code

kensu — Thu, 04 Feb 2021 01:59:10 GMT

I have a question about flashiap.c

/* Start signature address of the last sector*/
#define START_ADDR_LAST_SECTOR 0x1A070000

Why does the last sector is 0x1A070000, how to calculate this address?

In my understanding, flash base is 0x14000000, I don't know hwy the sector 14 is 0x1A070000

Please teach me.

Regards

Ken

Hello kensu,

This address is for LPC18xx with on-chip flash, for LPC1830, this space is reserved.

For on-chip flash, yes, the start address of last sector is 0x10A70000:
