Experiences with IAP

2004-08-24 by embeddedjanitor

Part is an LPC2129 week code 0350 at 12MHz with boot fimware 1.53.

The protocol I use for my boot monitor can only transfer up to 128 
data bytes per message so I thought I'd use the partail page 
programming discussed in various threads. This kinda worked but not 
properly and some corruptions were occuring.

I know that the corruptions were not my doing because they were 
random bit errors. ie. most bytes are right and in the right place 
but every now and then a bit was flipped. 

I eventually gave up on partial page programming and instead download 
512byte pages as 4x128byte transfers then when a full 512byte page is 
available the whole thing gets written. Works fine....

In summary, the partial page programming is not reliable (unless the 
new bootloader code fixes this issue), but full programming looks 
fine.
