can't connect to NINA-W102 #442

Closed br0kenpixel closed 9 months ago

I'm trying to use espflash with a u-blox NINA-W102 module connected to an Arduino Nano RP2040 Connect.

My Arduino board is flashed with the SerialNINAPassthrough example. I can connect to the module using esptool.py just fine:

$ esptool.py --port /dev/cu.usbmodem141301 --baud 115200 --before no_reset flash_id
esptool.py v4.3
Serial port /dev/cu.usbmodem141301

However, espflash can't connect to it:

Hi! Do you mind trying to use #387 and see if the issue is solved?

cargo install cargo-espflash --git https://github.com/AVee/espflash --branch add_unix_tight_reset

Hi. I tried it and still no luck.

I was thinking that maybe the issue is that espflash is trying to reset the board, which is not necessary in this case, as the SerialNINAPassthrough sketch forces the ESP32 into download mode. This is why I had to use --before no_reset with esptool.py. Does espflash have a switch for skipping the reset?

Hi! Sorry for the late reply, there is no --before no_reset equivalent in espflash at the moment. Maybe you can try using #487

SergioGasquez commented 9 months ago

Hi! Would you mind verifying if the issue still persists with the changes on main? 

cargo install espflash cargo-espflash --git https://github.com/esp-rs/espflash
