Read Me
Build the ESP32-S3 Linux Kernel
Based on the Max Filippov ESP32-S3 Kernel Linux Build Scripts and the Antonio Docker Container with a few modifications to make it work for me.
You will need:
- an operating system with Docker Support; and
- esp-idf
Build Instructions
sudo docker build -t esp32s3-linux .
Build time lasts for around an hour to be completed, you will have a 20GB docker image with the binaries needed to flash the ESP32.
Identify in your computer where is the serial port to the ESP32-S3, I will suppose it will by /dev/ttyACM0:
# give device access (ownership) to you current user
sudo chown $USER /dev/ttyACM0
Mount a container with the image you have just built from Dockerfile:
sudo docker run -it esp32s3-linux
Copy the container ID (let us suppose it is 78bdc7c38626) and copy the generated binaries to your native environment:
sudo docker cp 78bdc7c38626:/app/build/build-buildroot-esp32s3/images/ .
sudo docker cp 78bdc7c38626:/app/build/esp-hosted/esp_hosted_ng/esp/esp_driver/network_adapter/build/network_adapter.bin ./images
sudo docker cp 78bdc7c38626:/app/build/esp-hosted/esp_hosted_ng/esp/esp_driver/network_adapter/build/bootloader/bootloader.bin ./images
sudo docker cp 78bdc7c38626:/app/build/esp-hosted/esp_hosted_ng/esp/esp_driver/network_adapter/build/partition_table/partition-table.bin ./images
You may now delete the docker image and container, you won't need it anymore (if you don't want to cross compile any application).
Flash Instructions
Activate esp-idf environment wherever it have been installed, I will suppose it is installed in /opt/esp-idf:
. /opt/esp-idf/export.sh
Then navigate to images folder and run:
esptool.py --chip esp32s3 -p /dev/ttyACM0 -b 921600 --before=default_reset --after=hard_reset write_flash 0x0 bootloader.bin 0x10000 network_adapter.bin 0x8000 partition-table.bin
parttool.py -p /dev/ttyACM0 -b 921600 write_partition --partition-name linux --input xipImage
parttool.py -p /dev/ttyACM0 -b 921600 write_partition --partition-name rootfs --input rootfs.cramfs
parttool.py -p /dev/ttyACM0 -b 921600 write_partition --partition-name etc --input etc.jffs2
You will be able to access shell through serial monitor, you can use any application like putty, minicom, screen, Arduino...
minicom -D /dev/ttyACM0 -b 115200
press RST button on ESP32-S3 and enjoy!
