Missing xtensa-esp32-elf when install on Raspberry Pi

[whizzCoder]

When I followed the instruction for Linux to install on Raspberry Pi, the xtensa-esp32-elf folder is missing. Is it supported on Raspberry Pi?

Thanks.

Not officially yet, but you can build the toolchain on it and use it.

Thanks for the advise.
is there any instructions somewhere? :)

[me-no-dev]

I think on the esp-idf repo readme/docs. On the phone currently so its hard to find :)

[whizzCoder]

Thanks ... I'm still searching for the doc. :)

Hi everyone else, if you happen to know any place that I can download the toolchain for raspberry pi 3, or instruction on how to build the toolchain, please let me know. Million thanks. :)

Pre built binaries for rpi3 but it's not recent, also this video

Thanks for all the help.
I've started to compile the toolchain.
Almost 2h passed, likely many more to go. :)

The toolchain build took 170mins to complete.
I'm able to compile and upload a blinking LED sketch to my ESP32 dev board successfully.
Thank you all for your help.
Happy weekend!

Hi guys, I trying to do this but my knowledge in linux is not the best. When compile IDF, terminal return something similar

make all -j4 /home/pi/mcu/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc: 1: /home/pi/mcu/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc: Syntax error: "(" unexpected expr: syntax error /bin/sh: 1: xtensa-esp32-elf-gcc: Exec format error /bin/sh: 1: xtensa-esp32-elf-gcc: Exec format error Toolchain path: /home/pi/mcu/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc WARNING: Failed to find Xtensa toolchain, may need to alter PATH or set one in the configuration menu

What I need to do? I not understand "crosstoll-ng"...

ESP32 toolchain is not available readily for the Raspberry.
Some time ago someone compiled the toolchain for the RPi, but I do not know if it still works:
Building ESP32 toolchain on ARM (Armbian Raspbian)

@beegee-tokyo I followed the video tutorial a couple of weeks ago, and it worked just fine.

Well, sucess! I use crosstool-NG to recompile toolchain for arm (raspberry), worked perfecly in most recent master branch of IDF and last toolchain. Followed tutorial:https://docs.espressif.com/projects/esp-idf/en/latest/get-started/linux-setup-scratch.html.

140 Minutes to build toolchain
~7-12 Minutes to recompile /build of an project (when change menuconfig)
~5 Seconds to compile generic changes in code.

Really usefull and nice to "portable setup"

Hello
on a Raspberry Pi 4 with Buster is there a easy way to solve the problem!
