Hi,
There is no specific micropython image for the N32R8 Espressif S3 board.
You have to make it by yourself with some param values you'll find on previous topics.
This board work very well and is really a speeder board ;)

[gaurav0096]

Thanks for the quick reply @sophiedegran , i am very new to micropython, can you please help me to generate micropython image N32R8 using windows 10.

Maybe try the most recent nightly from Generic ESP32-S3 (SPIRAM Octal): it's most likely the bin file you want, rather than the app-bin (though I could be wrong).

The v1.20.0 build wasn't compiled with ESP-IDF v5, while the nightlies are

[gaurav0096]

Thanks for reply, it didn't work i have tried nightly builds

[sophiedegran]

Under windows 10 you have to install wsl and Ubuntu 20.04
After that see previous post (search for N32R8)
I use git for espressif 4.4
Take your time it's very simple .. and when you've done one it's very simple to compil

[gaurav0096]

thanks @sophiedegran i have followed the instruction 10359
now i am getting below error, after selecting from menuconfig

Error:

[sophiedegran]

Ok that's good! Don't use menuconfig just edit the file sdkconfig.board and do changes by yourself ...
check also sdkconfig.spiram_sx
verify also what mpconfigboard.cmake will do ..
You are with esp-idf 5.0.2 ? seem he can't find 'partitions-32MiB.csv'

[gaurav0096]

Thanks @sophiedegran its working

[sophiedegran]

You are the boss! You make it on esp-idf 5.0.2 ?

[gaurav0096]

i have used esp-idf v5.0.3.

I can see another thread regarding this OSError: (-24579, 'ESP_ERR_FLASH_NOT_INITIALISED') message:

I have a ESP32-S3-MINI-N32R8V and I had a similar issue with the -24579, 'ESP_ERR_FLASH_NOT_INITIALISED' error when using one of the builds available from micropython.org.

I was able to compile a custom build (using IDF 5.0.2 on macOS) - primarily I needed to modify the build to have the correct amount of flash (in this case it was CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y for the mini).

I don't know these board Esp32s3 Mini N32r8. There are a lot 'clone' from espressif and that is a shame..
Normally, N32 mean 32mo so flashsize = 32MB and give the partition custom file name = partitions-32MiB.csv
and of course declare this:
CONFIG_ESPTOOLPY_OCT_FLASH=y
CONFIG_ESPTOOLPY_FLASHMODE="dout"

First thing is to determine if your board is spiram or octal or boths!
Hope that help

[andypiper]

Apologies for the confusion, and thank you for the information about the way this numbering works!

My post above was incorrect - I have a ESP32-S3-MINI-N4R2 board, which is why CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y was the correct configuration.

[Amundw99]

How do you actually edit the sdkconfig file? Notepad editor?

[sophiedegran]

Which board do you have and the micropython version you want to install?

I have a tutorial on how to create an image for the ESP32-S3 Module with 16MB of flash. To do the same for the module with 32MB of flash, repeat the steps for 32MB. Pretty sure a 'partitions-32MiB.csv' exists in the MicroPython source tree where all the partition files are saved.
