Micropython ESP32 2MB flash

Post by tcpipchip » Wed Aug 07, 2019 7:26 pm

Sir,

I want to port the Micropython to U-BLOX NINA W102 (ESP32 with 2MB flash).

Is it possible ? If yes, wich of csv partition must i change to make the build and wich values of partitions did you use ?

I got succesfully ported the AT COMMANDS to NINA W102! But not micropython yet

Can you help ?

Very topical; Alex who makes the tiny Femtoduino products worked through the same problem yesterday.

He's raised a PR and there's now a discussion on how best to integrate this in mainline, probably by creating a board concept similar to the STM32 port. In the meantime you should be able to repeat his workaround.

Thanks to the help!

I can compile now to 2Mb...

And got 4 files bin

Problem is that reseting the ESP32...(NINA W102)...looks a bootloader problem...

Btw, do you know wich address i have to select to use to burn with Flashtools for the follwing bin files ?

bootloader.bin
firmware.bin
applicaton.bin
partitions.bin
