flashing bcAI:esp32 gets stuck

[vihaanb-v]

I am unable to flash the firmware to esp32 in aideck. It gets stuck at "Deck bcAI:esp, reset to bootloader"

bitcraze@bitcraze-vm:~/Downloads/aideck-esp-firmware$ cfloader flash build/aideck_esp.bin deck-bcAI:esp-fw -w radio://0/80/2M Reset to bootloader mode ... nRF51 has: sd-s130 and requires None and upgrade provides None. Current bootloader version is [2024.10.0] and upgrade provides [None] No need to flash nRF soft device Could not save cache, no writable directory Could not save cache, no writable directory Deck bcAI:esp, reset to bootloader

Can you please suggest how I can resolve this issue?

Ok, I want to report that I was able to solve this using JTAG (when you cannot do it over the crazyflie radio). I was able to write the firmware to esp32 by doing the following:

1. Used Olimex ARM-USB-TINY-H to connect to the correct ESP32 JTAG (right side) pins. Follow the link https://www.bitcraze.io/documentation/repository/aideck-gap8-examples/master/development/jtag-programmer/#jtag-connectors carefully.
2. Then follow the README in this GitHub page to flash using the JTAG, namely:
3. docker run --rm -it -v $PWD:/module/ --device /dev/ttyUSB0 --privileged -P bitcraze/builder /bin/bash -c "source /new_home/.espressif/python_env/idf4.3_py3.10_env/bin/activate && make"
4. docker run --rm -it -v $PWD:/module/ --device /dev/ttyUSB0 --privileged -P bitcraze/builder /bin/bash -c "openocd -f interface/ftdi/olimex-arm-usb-tiny-h.cfg -f board/esp-wroom-32.cfg -c 'adapter_khz 20000' -c 'program_esp build/bootloader/bootloader.bin 0x1000 verify' -c 'program_esp build/aideck_esp.bin 0x10000 verify reset exit'"

Glad you managed to work around the issue, but let's try to see if I can reproduce it all the same. Are you using a regular Crazyflie 2.x or a Brushless version? Were you on latest release firmware?

I also seem to have the same issue with one of my AI deck where I must use a JTAG programmer to flash the ESP32 because it refuses to work with the cfloader.
While for 2 other AI deck flashing with the cfloader works as expected.

Does the flashing through cfloader still fail after you flashed it with JTAG once?

Yes
