LPC812: IAP

Team, Sorry if this is a repeat question. Any one with success on IAP on lpc800max?

I understand that if I use IAP with the next restart the data may get erased. However when i move to production, I can use the IAP like EEProm

appreciate your help

Hi siva,

I did an update on IAP code.
Please try and if you have any problem, please let me know.

http://developer.mbed.org/components/IAP-In-Application-Programming/

Now this code works on LPC1768, LPC11U24, LPC812 and LPC824.
(On LPC800 series, the page-erase feature supported.)

Tedd Thanks a bunch. AFter we posted we were did something close. We will use it to make sure all is well. Will take us about a week.

One more question: If I shoudl move to produciton wtih the Mbed code then IAP shoudl work right? My understanding is that it doesnt work now becasue with every boot of the MCU the system overrides flash and puts in new code causing IAP to be overwritten. Kindly let me know if my understanding is right. Storing data is quite critical to my application

That's right. The data which is written by IAP will be kept.
If your system doesn't have the "mbed-interface" chip, no body erases the contents of the flash.
