Other RP2040 boards • Re: RP2040 + W25Q128JW successfully programs over SWD but doesn't run code

The only difference between the two sets of code is that the pico uses the pico-sdk PICO board preset while my custom board uses a custom one where the memory size has been changed. I am going to try and do a more in depth assembly analysis to see if there are any differences in code.
So build one way for the Pico and it works on a PIco, build a different way for your board and it doesn't work with your board.

I would suggest running the code built for the Pico on your board and seeing if it works - I would expect it to.

I would also suggest running the code built for your board on the Pico and seeing if it works - I would not expect it to.

You need to determine if it's simply a build issue or a hardware issue with your board.
