Build for ESP32-S3

[ElFishi]

I managed to build the binaries for an ESP32-S3. But only for flash_mode DIO. This post contains my latest version.

Maybe this write-up helps someone.

I use Windows/WSL/Ubuntu.
From your target directory clone the latest tag from github and change to the project dir

git clone --recursive --branch build-number-1698 https://github.com/sle118/squeezelite-esp32.git 
cd squeezelite-esp32

S3 needs a bespoke sdkconfig.
I used the version from @anabolyc and set the flash size to 16MB.
sdkconfig.s3.txt
Copy this to be your sdkconfig (see below).
If you want your build to get a bespoke name, also modify version.txt.

To build use the docker image by espressif

docker run --rm -it -v $(pwd):/squeezelite-esp32 -w /squeezelite-esp32 -v /dev:/dev --privileged espressif/idf:v4.4.7

4.4.8 does not produce a working squeezelite app for me (edit: it does, see below).
Inside the docker container install the dependencies and remove any prior build

pip install --upgrade pip
pip install protobuf==4.25.6 grpcio-tools==1.62.3
rm -rf build sdkonfig
idf.py set-target esp32s3
cat sdkconfig.s3.txt >> sdkconfig
idf.py menuconfig 

in menuconfig change the flash_mode to DIO if you want to avoid the issue linked to above.

idf.py build -DDEPTH=32
idf.py flash

In menuconfig you can change parameters like flash size etc. I found you have to run it and the subsequent fullclean even if you do not change anything.
In build you can set depth to 16 or omit it for 16-bit.

Insteead of flashing from the WSL you can use the Espressif Flash Download Tool.

To find the binaries exit the docker and run explorer on the build directory

exit
explorer.exe build

very cool - going to try

CORRECTION:
I edited the recipe above and removed my changes to the partitions.csv
Initally I had problems switching to squeezelite from recovery:

Booting to Squeezelite
I (29096) messaging: Rebooting to ota_0
I (29106) esp_image: segment 0: paddr=00210020 vaddr=3c160020 size=aa330h (697136) map
I (29186) esp_image: segment 1: paddr=002ba358 vaddr=3fc971f0 size=04fa4h ( 20388) 
E (29186) esp_image: invalid segment length 0x5f676e69
E (29186) messaging: Unable to select partition for reboot: ESP_ERR_OTA_VALIDATE_FAILED

I concluded that the partitions were overlapping but that was wrong.

I fell back to the original partion table and reduced the flash options to 40M frequency, DIO mode and 115200 baud.

With this configuration I now have a working squeezelite-ESP on an ESP32-S2-WROOM1-N16R8.
Maybe the flash chips on the cheap aliexpress devkits I have are not up to more speed in flashing.

CORRECTION 2:
again I edited the recipe above.
I went back to flashmode QIO and frequency 80Mhz in sdkconfig.
But this only works if you run idf.py fullclean after idf.py menuconfig.
Whenever I missed this step I ran into the validation issue mentioned above.
Same with idf 4.4.8, only 4.4.7 works for me.

CORRECTION 3:
only DIO produces reliable results. For QIO I have this issue

[anabolyc]

I was able to produce a working build using the latest master commit. It flashes and runs, but when I try running Spotify Connect it crashes every time

Ideas?

[anabolyc]

LMS works well by the way, tested with Music Assistant. Airplay also running without issues

[ElFishi]

I don't have a spotify account anymore. I guess that means I can't test it, can I?

[anabolyc]

Yes, I think you have to have premium account

[anabolyc]

I got it now. It was missing clientid and secret for Spotify. I'll update installer today and release for testing. It seems to be working well for S3. Classic ESP32 hasn't tested yet.

[ElFishi]

Great.
Make sure you test cycling between squeezelite and recovery.
Iirc I once tested a version from your web installer which wouldn't switch to recovery.

[ElFishi]

I did some edits to my sdkconfig.
Deviating from the above recipe I copy it to be my `sdkconfig.defaults' and just start building after removing the build directory.
sdkconfig.defaults.txt

Also I now use idf:v4.4.8 at the end of the docker command.

This sdkconfig is set to CONFIG_ESPTOOLPY_FLASHMODE_QIO=y.
You can change that to DIO in idf.py menconfig or you can tweak the binaries like this.

Seems to work now with both ESP32 and ESP32-S3, everyone welcome to test it: https://sonocotta.github.io/esp32-audio-dock/
