Flash an example of espressif with jtag programmer on ai deck board

[mvtkurd]

Hi everybody,

I want to flash tcp example of espressif on ai deck . I used these commands $ source ~/path/to/idf/export.sh $ idf.py build as you referred in the esp32 repository and I built the binary file but I don't know how could I flash this binary file with ARM-USB-OCD-H jtag programmer on the board. Thanks.

Hi,

There's more information on how to build and flash the ESP32 via JTAG in the repository readme. You can use the docker builder image for the flashing (you can do this even if you're not building the firmware with the builder):

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'"

@evoggy I got this error using the mentioned command:

Ok, strange. It seems to identify the targets but it cannot reset it the ESP32. Is it just the AI deck connected to the Crazyflie? Could you try to push the connector a bit in case there might be a glitch?

[mvtkurd]

yes only aideck is attached. I've checked the connections with multimeter and seems everything is fine but for one time I got this error(attached picture) instead of previous one.

Just a question here as I have experienced this before: From which OS are you trying to flash the ESP? Ubuntu, Windows, WSL?

[mvtkurd]

I'm using Ubuntu. In fact , the bitcraze virtual machine.

Hmm interesting. I've had the same issue when I connected my programmer's usb to WSL which is also a virtual machine ... but on a native install of ubuntu I didn't had this problem. I wonder if the virtual machine USB is suitable for a programmer but I can't find anything online that supports this.

This requires more investigation probably. It's an annoying problem.

Do you perhaps have a different programmer like a j-link to try? or a computer with a native install of ubuntu?
