The actual size isn't important is it? Your program area size is fixed by the firmware version.

MM.INFO(HEAP) is important as it directly concerns the operation

Any spare RAM is allocated to A:/ automatically IIRC. You don't get extra program area to play with.

There is also MM.INFO(OPTION FLASH SIZE) if that's of interest, but you can't do much about it. :)

I think that when Bill says RAM he actually means flash memory. There is no function in the PicoMite firmware to control the amount of flash memory used and it will probably stay that way. This is because, when the firmware is first loaded, it checks how much flash is present and uses anything not needed by the firmware for the internal flash drive (A:). You cannot subsequently change the amount of flash used without corrupting the flash drive (A:).

I tried to keep it simple with the PicoGamer by offering constructors an image that included everything (MMBasic, menu, games, etc) in the one file. However, it would be handy to also supply these components as individual files (as Volhout and Peter suggested). Then you could use whatever firmware you liked. This is still on my list of things to do real soon.

Hi,

I couldn’t resist and went ahead and got the parts for the PicoGamer. Flashing the Waveshare RP2040-Plus with 4MB went smoothly, but I can’t get access via Tera Term.
The COM port is there, the heartbeat LED is blinking, but nothing comes through via Terminal or Tera Term.
A test with the standard Picomite firmware runs perfectly, and Tera Term works.
I used “PicoGamer_V1.0_4MB_Flash.uf2”—am I doing something wrong?

I assume that the PicoGamer works normally (ie, it starts up showing the PicoGamer menu on the LCD panel). This is because the firmware image is configured to automatically start running,

To see something on the console (ie, TeraTerm on the USB console) you need to interrupt the running program with CTRL-C on the console. Does this work?

Thanks, Geoff, for the quick reply.
That would explain it. I haven't soldered the board yet because I'm still waiting for some parts.

Yes, pressing Ctrl-C works!!
