Nano Connect RP2040 - Dualbank support #7978

Open dextermarkley opened 1 year ago

dextermarkley commented 1 year ago

The Nano Connect RP2040 has 16mb of flash and may be able to support dualbank.

Does anyone know of any blockers for implementing this?

dextermarkley commented 1 year ago

The dependency rabbit hole goes a deeper than I hoped for each port.

esp_ota_ops.c looks port specific and a significant chunk of code that is beyond my C expertise.

Are you hoping to update CircuitPython over the air or the Nina firmware?

@tannewt Does the RO2040 Nano support Circuit Python over the web workflow or is that like an ESP32 thing? A friend just got one and we've been struggling to get REPL working over the web workflow.

anecdata commented 1 year ago

web workflow is supported on ports with native wifi... that's ESP32 variants (as the main MCU), and Pico W

RP2040 Nano is not supported because it is an RP2040 connected to an ESP32. (We call this an airlift for adafruit products.) We are moving to a single core solution with ESP. So, I don't expect we (Adafruit-funded folks) will ever add it.

@anecdata @tannewt Appreciate the context and information!

Very new to hardware, and community help has been very helpful.

Have a great week ahead!
