i will reply you here arduino/ArduinoCore-mbed#318
from docs-content.
As @pennam found out, the problem can be solved by going back to the mbed-core version 2.3.1 (instead of 2.4.1).

Hi,
Sorry for the slow reply. Due to the (not so) recent issues with supply chain we're mounting different flash chips depending on availability. While those are mostly compatible with each other, some have slight changes that require fw adjustments. In this specific case the issue can be solved by compiling sketches using the latest core which is of course backwards compatible with all other chips. If you already flashed a board with code compiled with an old core you need to recover by resetting the board while shorting the rec pin with ground. Please make sure you remove the short after reset, before flashing.

I managed to fix the issue, but other might still get the problem!

Does 'the latest core' refer to Mbed OS Nano Boards 2.4.1? I'm having the same issue, even a blinky sktech fails to boot after uploading.

You write: "...In this specific case the issue can be solved by compiling sketches using the latest core..."
:
How can I achieve this when working with a 3rd party library ?
Does the library creator need to implement the latest core first ?
Or can I do that by myself. If yes, how exactly (i.e. step by step explanation please).
I already tried:
- I connect pin GND to pin RESET (or REC as you call it)
- I power the board by plugging in the USB connector
--> I observe the RPI-RP2-drive cropping up on my desktop screen - I disconnect pin RESET from GND
- I download the WiFiManager_NINA_Lite library's Example
i.e. in Arduino IDE under Examples --> WiFiManager_NINIA_Lite --> RP2040_WiFiNINA - At startup, still the same error :
Starting RP2040_WiFiNINA on MBED NANO_RP2040_CONNECT
WiFiManager_NINA_Lite v1.4.0
[WN] Hostname=RP2040-Master-Controller
LittleFS size (KB) = 64
LittleFS Mount Fail
Formatting...
Can you please explain better, step-by-step how you solve this problem with the library of concern ? Thank you.

Hi @iKK001 regarding issue arduino/ArduinoCore-mbed#318 you have already installed the latest core, so the new flash chip is already supported. I'm thinking you are facing a different issue otherwise your sketch wont even boot. What is the return value of the mbed mount function?

Could very well be. Circuitpython had the exact same problem. When the new flash chip was added the configuration, the problem was solved.

Hi @pennam : How do I get the return value of the bed mount function ? (step by step explanation needed since I am not an expert).
I have certain sketches that work nicely with the board - but not the library of concern.
Can you please look at the library of concern - which is the library WiFiManager_NINA_Lite ? I need a solution for this particular library. And the library owner (khoih-prog) keeps telling me that it is a hardware problem that is the root cause of his library not working.
Can you please talk to each other to clarify the issue ? The library of concern is widely spread enough, I think, to consider it.
