Building image for esp32s3 target

[halsbox]

Hi! What branch/tag should I use for building esp32s3 images? What's the command to build for esp32s3? What env variables should be set when building image? Where in source tree (including git submodules) should I search for and add my own board .h files (e.g. to set LED type/pins) I did a brief grep through source tree (including *-sdk) on master branch and tried running cmake with ESP_PLATFORM=1 but didn't manage to get it building. Will appreciate any help.

You don't need nothing special.

If you have configured your VS Code with ESP32 plugin, the project is built smoothly.

Thanks! Got it building with custom vid/pid. On linux I had to patch pico-keys-sdk/src/esp_compat.h:

diff --git a/src/esp_compat.h b/src/esp_compat.h
index 0379c13..6266058 100644
--- a/src/esp_compat.h
+++ b/src/esp_compat.h

 #ifdef ESP_PLATFORM

 #include "freertos/queue.h"
 typedef QueueHandle_t queue_t;
 #define queue_init(a,b,c) do { *(a) = xQueueCreate(c, b); } while(0)

Also found nothing VSCode specific. Any or no IDE is OK, general instructions would be:

git clone --recursive https://github.com/espressif/esp-idf.git && cd esp-idf
./install.sh esp32s3
. ./export.sh
cd /path/to/pico-fido/
idf.py -DUSB_VID=0x**** -DUSB_PID=0x**** all

Can you show me how you do this? I would be very grateful for a tutorial video! Developer does not help!

Hi, @metabo7000! Please provide what OS do you use. I did build it using my Linux desktop. For linux you need git installed and do:

1. git clone --recursive https://github.com/polhenarejos/pico-fido.git

2. change #include "freertos/freertos.h" to #include "freertos/FreeRTOS.h" in pico-fido/pico-keys-sdk/src/esp_compat.h
3. Follow "Step 1. Install Prerequisites" from https://docs.espressif.com/projects/esp-idf/en/stable/esp32/get-started/linux-macos-setup.html#get-started-prerequisites
4. (replace asterisks with your desired vid and pid)

   git clone --recursive https://github.com/espressif/esp-idf.git && cd esp-idf
   ./install.sh esp32s3
   . ./export.sh
   cd ../pico-fido/
   idf.py -DUSB_VID=0x**** -DUSB_PID=0x**** all
   idf.py flash

@metabo7000 just checked docker build is OK. If you own any OS with docker installed you can build using docker.

1. clone https://github.com/polhenarejos/pico-fido.git including submodules using you preffered tool.
2. patch pico-fido/pico-keys-sdk/src/esp_compat.h to include case sensitive "freertos/FreeRTOS.h" as I mentioned above
3. go to cloned directory (e.g. cd pico-fido) and run:

   docker run --rm -v $PWD:/pico -w /pico -u $UID -e HOME=/tmp espressif/idf idf.py -DUSB_VID=0x**** -DUSB_PID=0x**** all

4. your build firmware binaries are located in build subfolder.
