Web flashing tool: Make a single action to flash firmware and nvs at the same time.

[SmittyHalibut]

I use the web flasher to program boards in bulk when I have them fab'd. Right now, I have to:

• click flash firmware
• select the serial port
• tell it to flash
• yes really
• wait for flash
• click next
• close that window.
• Then click NVS for my PCB version and band
• select the serial port again
• click Install manifest
• next without erasing
• click install
• wait for NVS
• click next
• close that window.

...for every board...

I would prefer a single process that goes roughly like this:

• Click button to select PCB version and band (similar to current NVS options)
• Select serial port
• Click Install
• Confirm install
• Exit all the way back out to the main page without having to close any "Install complete" windows or anything. Or, if there's an "Install complete" modal, give it a button to "Do it all again?" where it restarts at selecting the serial port.

Let me know if you have any further questions.

I’ve been doing bulk programming with a tiny esptool script instead of the web UI.

esptool can flash multiple address/file pairs in a single write-flash, so the workflow becomes: plug board → run one command → unplug → repeat.

Example:

esptool --baud 900000 write-flash  \
  0x1000  android-src/KV4PHT/app/src/main/res/raw/bootloader.bin \
  0x8000  android-src/KV4PHT/app/src/main/res/raw/partitions.bin \
  0x9000  pcb/v2.0d/board-config-vhf.bin \
  0xE000  android-src/KV4PHT/app/src/main/res/raw/boot_app0.bin \
  0x10000 android-src/KV4PHT/app/src/main/res/raw/firmware_v15.bin

Example output:

esptool v5.1.0
Connected to ESP32 on /dev/cu.usbserial-210:
Chip type:          ESP32-D0WD-V3 (revision v3.1)

Heh. Fair 'nuf. Can someone make that a script in the repo (if it isn't already)? Worst case, I'll do it the next time I have to flash up some boards.
