When I change (only) the flash size to 8MB (leaving partitions.csv unchanged) , copy build/sdkconfig to boards/sdkconfig.base, run make and make deploy, the boot process of the ESP32 gets into a loop, ..... I haven't tried your suggestion for the partition change yet. Well, you absolutely need to c...

False alar, pilot error.

With recent uploads of GENERIC esp32 firmware., gc.collect() can cause panic and lead to a hard reboot. I have observed this with all esp32 GENERIC firmwares since and including esp32-20210222-unstable-v1.14-80-g75db0b907.bin, using a standard esp32-WROOM. An issue has been raised https://github.com...

@robh: With a properly set-up IDF4 environment, idf.py menuconfig will (well, should) take you into a menu structure that allows you to make various settings before the compile. “Serial flasher config” for instance allows you to choose FLASH size up to 16MB. Menuconfig produces an sdkconfig file in ...

Thank you, @Jimmo

I think this is the case. You will need to copy whatever menuconfig generates for you into sdkconfig.board Thank you. I have copied the menuconfig file to .../ports/esp32/boards/GENERIC_SPIRAM/sdkconfig.board (I guess that's where it's supposed to go) which contains the proper instructions: # CONFI...

Live ad learn, and unlearn ... So the reason that MicroPython on the Pico is special isn't that _thread behaves differently, rather that it runs without a GIL. If you turned off the GIL on the ESP32 port (and disabled core pinning) then it would behave the same way. Interesting. Could you provide so...

I found what is happening, but I don’t why: /esp32/boards/sdkconfig.base is being used instead of the sdkconfig file produced by menuconfig. In /esp32/boards/sdkconfig.base, if I make this edit, the compile finishes successfully: #CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y CONFIG_ESPTOOLPY_FLASHSIZE_16MB=y Th...

I am still (see my comment in https://forum.micropython.org/viewtopic.php?f=18&t=9820 battling with the new Cmake version when it comes to larger flash sizes. It simply won’t compile for anything larger than 4MB Previously, I put these into Makefile BOARD ?= GENERIC_SPIRAM FLASH_SIZE ?= 16MB My part...

@Jimmo: Yes, the Swiss Guy is in the video. As for _threading using multiple cores on the Pico: Very confusing. It has been drummed into Python coders that with Python, multithreading is not what one would expect, and that Python multithreading uses the same core, and that for multiple cores, one ne...
