Can't get Micropython to reinstall

[codiak6335]

I successfully built and installed the Micropython, boot, and partition bin files.

While playing around with the logo py example I set up a while true loop that blicked the backlight off and on with a 1-second sleep cycle. The code worked great.... too great... as I could not break the loop and stupidly had modified boot.py

Nothing I seemed to do would break the loop.
I did manage to use esptool to erase the flash but attempts to reinstall the 3 binaries never restored function. Thonny can not reconnect...

Thinking I bricked the device I shifted to Arduino IDE 2.0 and was easily able to get the C "Progress" demo running. With a sigh of relief, I then attempted to reinstall Micropython... again, success messages... no Thonny connections , and if I wait long enough the Progress demo restarts (like a bad penny it keeps turning up)

so the chip works, just not for MP... and I am at a loss how to progress

I was able to reinstall the generic ESP32 Micropython and it seems to be working as expected. No success in reinstalling the lilypad repo yet

Good success getting Mpy stable! If you are interested in getting your T-Display S3 running can I suggest my own repo?

https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples

I had a bad time at first and was convinced I’d bricked it, so I detailed what works for me. My setup text is very procedural, I’m afraid, but it will get you to a running Arduino T-Display with a demo program and you can branch off and go from there.

Don’t hesitate to contact me.

Cheers ! Terry

Thank Terry, I visited your repo over the weekend, and while informative didn't resolve this issue.

I finally found a solution and have recovered with the display working. I had upgrade esptool.py to version 4.4 something after originally getting the MCU working.

This command line was actually failing: esptool.py -p /dev/ttyACM0 -b 460800 --before default_reset --after no_reset --chip esp32s3 write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x0 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/bootloader/bootloader.bin 0x8000 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/partition_table/partition-table.bin 0x10000 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/micropython.bin

However, installing each bin file separately works fine:

esptool.py -p /dev/ttyACM0 -b 460800 --before default_reset --after no_reset --chip esp32s3 write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x0 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/bootloader/bootloader.bin

esptool.py -p /dev/ttyACM0 -b 460800 --before default_reset --after no_reset --chip esp32s3 write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x8000 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/partition_table/partition-table.bin

esptool.py -p /dev/ttyACM0 -b 460800 --before default_reset --after no_reset --chip esp32s3 write_flash --flash_mode dio --flash_size detect --flash_freq 0x10000 ./build_dir/esp32s3/build-LILYGO_T-DisplayS3/micropython.bin

Thanks for getting back to me. I am an Arduino C guy, and do not know python.

Cheers ! Terry Stainton
