LoPy4 Firmware upgrade impossible

[dicktonyboy]

@robert-hh grand kids have arrived - must play grandpa for a moment -will get back to you with the results Thanks for all of your help.

This board will NOT flash. Even trying lower speeds it does not correctly switch modes. The blue heartbeat led stops as it should when the pin is grounded but nothing more.

@dicktonyboy So did you see the message "waiting for download" in Putty, if you do the download preparation steps, or not?

[dicktonyboy]

@robert-hh No just the original message I posted - repeated several times and can you remove this annoying restriction that pops up each time I reply please

Error

@dicktonyboy If you do not see the message, then something may be wrong with P2 aka GPIO0. The sequence of messages you see is also strange.

Remark. I gave you 3 reputations. So the delay should be gone.

@robert-hh Well this is very weird as to all intents and purposes everything else is functioning correctly. I am new to this - and this is my first LoPy project. I'm running TTN Cardiff and wanted to provide the locals with a signal strength mapping project. https://youtu.be/-H-W76OMkyY?t=16s I feel so much cleaner with my new-found reputation - thank you for that!

@robert-hh I've no ideaa whether this is of an help but the response to:-

C:\Users\dicktonyboy>ampy -p com7 ls
flash

and the response to:-
C:\Users\dicktonyboy>ampy -p com7 ls /flash
main.py
sys
lib
cert
boot.py
Location History.json
AdafruitIO.py
filer
umqtt.py
project.pymakr
lopylcd.mpy
micropygps.mpy
micropygps.py

I can't delete the bottom three files or Location History.json (probably due to the space in the name)

@dicktonyboy If you have the REPL prompt, you can always reformat the internal file system with uos.mkfs().
But updating requires the device to be in upload mode. Sorry if I'm asking the obvious again, but are you sure that you connected P2 to GND. That's the 4th Pin from the edge close to the reset button, next to TX. Strapping it low sometime causes the RGB LED to switch colors.

[dicktonyboy]

@robert-hh double and triple checked - correct. :)

[robert-hh]

@dicktonyboy You could check, whether P2 is connected at least to the RGB Led. It is one of the connections faced to the LoPy Shield, opposite to P2.
