Isn't the internal ROM on the RP2040 only 16kB and not 16MB?I now have a requirement to use up to 12MB at a time so ive switched to using internal ROM (the rom is 16MB) and I get some data but the data is being served at a reduced pace.
Can you share any of your PIO code? It isn't clear how you are reading the data addresses, passing addresses between the two state machines, or how the second state machine would read the required data and send it out over the data lines. Where do the RAM and/or ROM accesses even come into this state machine data flow?The SM configuration is setup for once SM to read the incoming data address, pass the address to the second SM and that one outputs the data over the data lines.
