micropython-stubber mpflash: Failing flash without --serial

reported by @wovo

The unneeded firmware scan is done when --serial is not specified ( either explicit or as '?') in this case there is a pile-on effect as the board is not correctly identified and tha flash fails.

mpflash v0.7.6 has been updated to interactively ask for the serial port if --board ? has been specified but no --serial has been specified. in addition the list of serial ports has been improved by adding the comports description (if available) .

mpflash flash --board ? Should allow you to select the serial port ,Micropython Port , and Board and then continue to flash the esp32/esp8266

@wovo, @beetlegigg Could you verify if this version works for you ?

Below a sample run

BTW This looks as if it will be a very useful tool and thanks for your efforts. No luck with the install on my macOS yet. I post the terminal output so you can see the commands I entered.

Thanks for testing - I understand the error you are experiencing on the rp2. the flash process for the rp2 and other .uf2 boards is :

get the board details
run the mpremote bootloader command. This causes a rp2 to restart and it should show up as a drive
on linux this may not be the case ( depending on lots of things) - and thus I use the pumount utility to mount / unmount the drive to the filesystem
I assumed this would also work on mac , but alas this works different on macos

the ignore is for all commands - to it should be like this: mpflash --ignore cu.Bluetooth-Incoming-Port list or mpflash --verbose --ignore cu.Bluetooth-Incoming-Port list to show more info

What I can do is make a change so at least the pumount tool is not used on macos. Ill post an update here If I have something to test.

as far as I am aware this now works as expected, but I have no hardware to verify first hand. Please feel free to re-open if this this is still a problem
