Hello everyone,

I try to get started the IAP-Function for programming and erasing the on-chip flash memory.

In my project I've already implemented the functions from AN10995.

On the LPC1115F/303 all the routines are working. I have no problems erasing and programming one or more flash sectors.

However on the LPC1112FHI33/202 the "CopyRAMToFlash" routine doesn't work. The return value is "IAP_STA_SRC_ADDR_NOT_MAPPED".

Does anybody know the reason for this problem?

The LPC1112 which I am using belongs to another serie. Maybe there is something missing. But I didn't find any informations.

Thank you.

Thanks for your answer.

Now it is working. I changed my source variable from local to global.

But I still don't understand the reason why it is working on the LPC1115 device with a local source variable.

Regards

Hi,
Sounds like the memory you are using is not available on the LPC1112 device.
Check the memory map between the devices and ensure the source and destination addresses exist as valid memory locations.
