From Wokwi to a real device
- Compile the code and on the code editor press F1 to download the firmware. It is a .bin file, let's name it sketch.bin file
-
esptool.py --chip esp32 --port "/dev/ttyUSB0" --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode keep --flash_freq keep --flash_size keep 0x1000 "bootloader.bin" 0x8000 "partitions.bin" 0xe000 "boot_app0.bin" 0x10000 "sketch.bin"Once partitions and bootloader are uploaded, you can simply upload the sketch. To upload for the first time the partitions and the bootloader you can simply used arduino IDE -
esptool.py --chip esp32 --port "/dev/ttyUSB0" --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode keep --flash_freq keep --flash_size keep 0x10000 ./sketch.bin
In principle you can even use a Web tool
