According to the reference manual, the main flash memory (cortex-M4) can be programmed 16 bits at a time. Is the generated Intel hex file from Keil compiler already in even number of bytes?
Just a note here - the cortex core is irrelevant to this because it isn't the processor core that owns the flash memory.
Well, if Keil (an ARM company) hasn't got this right, their tools would be useless - wouldn't they?!
