toolchain for Raspberry PI 4 (8GB) ?

Postby jumjum123 » Wed Nov 18, 2020 11:31 am

Is there a toolchain available for ESP32 and/or ESP8266 running on Raspberry PI ?

Yes, ESP32 toolchain for 32-bit ARM is available. If you follow the getting started guides for Linux (https://docs.espressif.com/projects/esp ... index.html), it should be installed.

If you need to download the toolchain separately, the link is on this page: https://docs.espressif.com/projects/esp ... -esp32-elf

Thanks a lot for this. Tested everything and it works fine for ESP-IDF V4

And thats where my problem starts again, we are working on V3.
There are some good reasons for that, for example size of binary.
For that we need toolchain gcc_5.2 Is there anything available ?

And last not least, is something similiar available for ESP8266 ?

Yes, you should also be able to install it on v3.3. There is no documentation page for v3.3 with the list of the toolchain downloads, but the URL and SHA256 can be found here:
https://github.com/espressif/esp-idf/bl ... s.json#L46
There is no -armel toolchain for the ESP8266 from Espressif, I'm afraid. Please file an issue at https://github.com/espressif/ESP8266_RTOS_SDK/issues if you need it.
