I have a program that has several 16x16 tables that are stored in fixed locations in flash memory. I'm using Keil's compiler and using the _at_ attribute to do this, it works great. My tables change quite often but the code does not change at all. I'd like a way to be able to reprogram just the tables in flash and not touch the code section. I was wanting to use Philips Flash Utility (PFU from here on) to program JUST the table locations I want to change. I generate a hex386 file of just the table data and fire up the "Flash Buffer Operations" in PFU and load the hex file. My new tables show up exactly where they are supposed to be, but when I hit the "Upload to Flash" button PFU programs the entire flash memory. I have the "selected range" button selected with the proper range in it. The only way I've gotten this to work is to open the orginal hex file into a text editor and append the new table hex file to the end of it. Can I not just program certain pages in flash and leave the rest alone? Thanks...

Anyways, I'm using a LPC2194 and Martins web page said that LPC21ISP did not support the newer chips like the LPC2194 with 256K of flash. I've never tried it for that reason. Thanks for the reply!

You can try to programm small programm, but the newer chips have a different page structure. Usually you don't break anything, but it just reports an error. Regards, Martin

It should be straight forward, but apparently those with an interest haven't had either the time or a chip to work with. Robert " 'Freedom' has no meaning of itself.

Try using Keils JTAG loader. I have had to do the same sort of thing to test IAP erase rotines and I was able to fill the flash with a pattern and load code through the JTAG without disturbing the extra flash space. Make sure that, in the Utility settings that the flash loader is set to erase sectors, not the entire chip.

Yes I can do it that way, but the guys in the field don't have a seat of Keil's CKARM and JTAG loader. Was looking not to purchase another seat of CKARM :) It's no big deal appending the new table hex file to the end of the code hex file. The guys who are updating the tables or VERY non-techi and asking them to do this with a text editor is asking for trouble. I'll have to come up with a program or script that does it form them, then fires up the flash utility with the file loaded. Then all they have to do is push "Program". Thanks for the reply...
