Bootloader not working on ESP32S2 #56

Open os196 opened 4 months ago

os196 commented 4 months ago

I flashed the firmware onto my ESP 32s2. I am using the official Wi-Fi development board for the flipper zero. But whenever I open the gravity app on the flipper it gives me a invalid bootloader error . Is there any way to fix this?

You need to build the firmware yourself if you want to use the WiFi devoard. Pull the repo, delete the .vscode and .devcontainer dirs.

  1. Install esp-idf https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html#installation
  2. go to the directory of the repo and run . $HOME/esp/esp-idf/export.sh
  3. idf.py set-target esp32s2
  4. run idf.py menuconfig and select the following Components -> FreeRTOS -> Port: Place FreeRTOS functions into Flash (enable) Components -> ESP Ringbuf: Place non-ISR ringbuf functions into Flash (enable) Components -> ESP Ringbuf: Place ISR ringbuf functions into Flash (enable) Gravity Configuration -> Flipper
  5. idf.py build flash Since the devboard does not support bluetooth the precompiled binaries will break and never run. Hope this helps :)

It worked perfectly until I tried to flash it. Then it gives me a broken pipe message. Is this normal?

RoemIko commented 4 months ago

If the companion app works then yes its normal

os196 commented 4 months ago

It does not work like normal I don't think it was successful at flashing the Wi-Fi development board do you know why the broken pipe error could have been thrown?

No i do not know, if you did the steps i described above it should work. The only error i get is that i cannot use the terminal and that it says i have to use putty to perform commands (because of auto commands). But since im using the F0 companion app i ignored that error.
