Problem running an algorithm on OM13098(LPC54628)

RodrigoEngComp — Wed, 24 May 2023 13:34:51 GMT

I ported an algorithm from an OM 40003(LPC54018) to an OM13098(LPC54628), however, when recording the algorithm, apparently the 54628 first searches for something in the program flash, of 512kb, and not in the Board flash... But my algorithm is larger than 512kb in size and I can't write to this section.

What can I do to write to Board Flash and make it the first search address?

You can use this blog, where it tells you how to use the linker to record in certain areas of your lpc memory with MCUXpresso

Before starting this topic, I managed to link certain parts of the algorithm to external memory, but when calling this data, the board crashes...

And, do you have an example algorithm that uses the external flash memory from this OM13098 board?
