Flash Write Rate, Section Statement

Started by rf_equip May 1, 2008
Hello All,

I have two questions:

1 - What is the LPC21xx Flash programming speed? I am thinking about
using the a portion of the interal flash for "mode storage" I am aware
that I can wear out the part if I end up writing to the same location
but I am going to use a rolling memory scheme.

2 - I am writing a In Application Program Loader. I can write to
flash now. Next thing I like to do is to take my loader code and
locate it high address in the flash. The application program will look
for a particular command from a UART or a CAN port and then call my
loader code. I am not sure how use the .section command with C code
and Cross Works. I know how do this with Green Hills. I'd like to my
my loader code location absolute at link time. Any examples will be
appreciated.
