Copy and execution of a routine at runtime for cortex-m0 architecture

angelocalabrese — Fri, 07 Dec 2018 09:21:52 GMT

I'm developing a bootloader. I need to receive the flash erasing and writing routines from an external channel (via CAN). So I need to copy and then perform these routines in RAM. The prototypes of these routines are as follows:
uint16_t FLASH_Program (uint32_t wNVMTargetAddress, uint8_t * pData, uint16_t sizeBytes);
uint16_t FLASH_EraseSector (uint32_t wNVMTargetAddress);
How can I do it?

I posted some of the related Flash code in this thread a while ago:

The 'Copy' code is in the attached startup and linker files.

Real Soon Now I'm going to write a book with all of this stuff in it,

that should have been in Freescale/NXP documentation in the first place...
