ESPHome use on a Adafruit Matrix Portal M4

ESPHome

I’ve tried to setup a Adafruit Matrix Portal M4 based 64x32 display using this ESP Wrapper: GitHub - TillFleisch/ESPHome-HUB75-MatrixDisplayWrapper: Custom ESPHome component which wraps the ESP32-HUB75-MatrixPanel-DMA library into a ESPHome display component.
But I can’t seem to connect to the Matrix Portal after compiling. Has anyone used a Cortex M4 based device successfully?
Error in the log:
ERROR Please try running esptool.py --before default_reset --after hard_reset --baud 115200 --port /dev/ttyACM1 --chip esp32 write_flash -z --flash_size detect 0x10000 /data/build/info-display/.pioenvs/info-display/firmware.bin 0x1000 /data/build/info-display/.pioenvs/info-display/bootloader.bin 0x8000 /data/build/info-display/.pioenvs/info-display/partitions.bin 0xe000 /data/cache/platformio/packages/framework-arduinoespressif32/tools/partitions/boot_app0.bin locally.

I have had some success with changing the board to esp32-s3-devkitc-1
It flashes and shows up in home assistant. I only have brightness and power. I can not get anything to print on the display

I may have messed up the pin out. I’ll look into it more when I have time.

have you gotten this working? I have the same device and would like to see if I can get ESPhome working with it

I ended up not being able to get esphome to work with Adafruit’s Matrix Portal M4. I setup the Matirix Portal to receive messages over MQTT instead. I used the Arduino IDE in the Matrix Portal. Works, but on occasion the Matrix Portal stop receiving MQTT messages has to be rebooted.
