Re: Keil MCB2100 platform port (LPC2xxx based)


That would be great. Apart from the Synth target no hardware has
support for this, so it would be good to see it used for real. There
is probably some bugs still lerking in there for bootblocks.

If/when this port ends up in CVS I'll look into that.


first block where it actually boots from and the rest of redboot into
a large block higher up in the flash. This then leaves the smaller
blocks available for configuration information.

These parts (the ones with 256K flash) have two 64Kbyte blocks in the middle of the flash the rest are 8K so they're not like what I've seen before with top/bottom bootblocks.
The LPC flash is unusual in a few more ways: it is operated on by calling code in its bootloader software, so it does not expose the hw details;writes happen in 512,1K,2K and 8K chunks only IIRC. Anyway I am waiting for a board with 64K of RAM before doing flash programming, the one I'm working with has 16K.
