Try to flash Lilygo T Beam Supreme

[AlexanderGabriel]

Hi,

i try to get tiyuf2 running on a Lilygo T Beam Supreme.
I use esptool to flash downloaded release "tinyuf2-lilygo_ttgo_tbeam_s3-0.18.2.zip":
esptool.py --chip esp32s3 -p /dev/ttyACM0 -b 460800 --before=default_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 80m --flash_size 8MB 0x8000 partition-table.bin 0xe000 ota_data_initial.bin 0x1000 bootloader.bin 0x2d0000 tinyuf2.bin

after this, i reset and get errors on serial console

I would rather download the following: https://github.com/adafruit/tinyuf2/actions/runs/9785406115/artifacts/1665865293 and from this package just flash "combined.bin" at 0x0 using e.g. https://espressif.github.io/esp-launchpad/ in Chrome. After a reset your S3 will boot in UF2 mode and wait for a UF2 image to be loaded (e.g. SoftRF).

Thank you. SoftRF was my goal and your answer is exactly what i needed :)

Cool. You may then actually consider my SoftRF fork where you can modify the ICAO hex code: https://github.com/VirusPilot/SoftRF. I am providing UF2 versions as described here: https://github.com/VirusPilot/SoftRF/tree/master?tab=readme-ov-file#uf2-binaries
