Esptool Instructions? #1

Closed jouellnyc closed 1 year ago

jouellnyc commented 1 year ago

Hello.

I've just gotten the "LILYGO T7-S3 ESP32-S3 board with 16MB flash, 8MB PSRAM"

Are there steps for using esptool to flash?

I've tried:

esptool.py --chip ESP32S3  --port /dev/ttyACM0 write_flash -z 0x0000 ~/esp32/firmware/esp32spiram-20221111-unstable-v1.19.1-660-gc8913fdbf.bin  --force
esptool.py v4.3
Serial port /dev/ttyACM0

On boot gtmkterm will show:

Build:Mar 27 2021
rst:0x7 (TG0WDT_SYS_RST),boot:0x8 (SPI_FAST_FLASH_BOOT)

Invalid chip id. Expected 9 read 0. Bootloader for wrong chip?
ets_main.c 329 
ESP-ROM:esp32s3-20210327

Most options give errors regarding the chip id, that's why I tried --force:

esptool.py --chip ESP32S3   --port /dev/ttyACM0 write_flash -z 0x0000 ~/esp32/firmware/esp32spiram-20221111-unstable-v1.19.1-660-gc8913fdbf.bin

Unexpected chip id in image. Expected 9 but value was 0. Is this image for a different chip model?

A fatal error occurred: /home/john/esp32/firmware/esp32spiram-20221111-unstable-v1.19.1-660-gc8913fdbf.bin is not an ESP32-S3 image. Use --force to flash anyway.

Where is this firmware obtained from?

jouellnyc commented 1 year ago

Hello. Thanks for the reply. I've tried the firmware here: https://micropython.org/download/GENERIC_S3_SPIRAM/ and tried files like "GENERIC_S3_SPIRAM-20220618-v1.19.1.bin"

lbuque commented 1 year ago

There is currently no micropython firmware for the T7-S3.

you can try this firmware.

Thank you!

I have tried:

esptool.py --chip ESP32S3  --port /dev/ttyACM0 write_flash -z 0x0000 LilyGo-MicroPython_esp32s3_LILYGO_T-DisplayS3_MPY-d7919ea71_IDF-1b16ef6cfc_B20221024_a07409ec59.bin

It works now and I use it with Thonny IDE.

Thank you @lbuque !!!

This is the micropython firmware for T7-S3.

This is the board micropython configuration code of T7-S3.
