Flashing command

[markpeletier]

At #building-squeezelite-esp32 the following flashing command is given:

<path_to_your_python>/python.exe <path_to_your_esptool>/esptool.py -p %ESPPORT% -b %ESPBAUD% --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x150000 build/squeezelite.bin

If I try this on a WROVER that had previously been flashed with the Arduino IDE with a standard Blink example, then the ESP boots into the Blink example.

The Blink example has an esptool command line that contains four parts: two boot loader files, a partition list, and the Blink executable itself (at least, this is what I think they are). Also the example at https://docs.espressif.com/projects/esptool/en/latest/esp32s3/esptool/flashing-firmware.html#flashing shows multiple parts (three, in that case).

How should this work in the case of squeezelite? Is the command line above missing some parts?

It's not visible in the README, but there is more detail here: https://forums.slimdevices.com/showthread.php?112697-ANNOUNCE-Squeezelite-ESP32-(dedicated-thread)

There are two notable things:

1. The ESP used must have 4MB or RAM and at least 4MB of SRAM. The post mentions that WROOM modules are no good, and WROVER must be used instead. esptool does not seem to throw an error if it fills the module's RAM and there's still more file to write.
2. The command is now python ${IDF_PATH}/components/esptool_py/esptool/esptool.py --chip esp32 --port ${ESPPORT} --baud ${ESPBAUD} --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0xd000 ota_data_initial.bin 0x1000 bootloader.bin 0x10000 recovery.bin 0x8000 partitions.bin (Done from withing the build folder inside the zipped release)

And an update: As of #144, there is a web installer that does not need any of the esptool commands

You are correct. The web installer can be used to flash the initial firmware and from there, updates will be performed via the web interface
