Hello, I was experiencing slow Kinetis K60 writes using Olimex and Amontec FT2232-based dongles on a custom board I designed around a PK60N512VMD188, and looked into it a little bit. The question deals with the kinetis NOR flash driver.
I found that bypassing the logic which always causes program-flash writes to fall back to the slow longword flash-write command resulted in a significant increase in flash writing speed (470 bytes/sec to 52 kB/sec) and does not appear to introduce any problems, though to be fair, I've only done it maybe 10 times now. Unless I'm confused, the Freescale K60 datasheet (p. 677, section 28.4.12.8) describes the "Program Section" command as indeed being valid for program flash, and of course performing full 2kB page flash-write operations is much faster than a sequence of single longword writes. I just wanted to toss this observation out there and see if others have noticed this. I am happy to submit a patch if there are no objections.
