RP2040 Connect board has faulty components in newest purchase

[iKK001]

Using 8 out of the box new Arduino Nano RP2040 Connect boards, I have a problem with all of them concerning the library WiFiManager_NINA_Lite.

Two months ago I already purchased an Arduino Nano RP2040 Connect board - and this one works nicely with the above library.

Now I think that there is a different Flash-memory component (or other) on the newly purchased faulty boards.

I am already in contact with Arduino Store to return those 8 faulty boards.

But maybe somebody from the ArduinoCore-mbed team has an idea what is going on.

Running the following default-Example I get the following Error message:

--> Example --> WiFiManager_NINA_Lite --> RP2040_WIFININA :

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... 

Or running the following two default-Examples I get the same Error message:

--> Example --> LittleFS_Mbed_RP2040 --> LittleFS_Counting

Start LittleFS_Counting on Nano RP2040 Connect
LittleFS_Mbed_RP2040 v1.0.2
[LFS] LittleFS size (KB) = 64
[LFS] LittleFS Mount Fail
[LFS] Formatting... 

or respectively, --> Example --> LittleFS_Mbed_RP2040 --> LittleFS_Test

Start LittleFS_Test on Nano RP2040 Connect
LittleFS_Mbed_RP2040 v1.0.2
[LFS] LittleFS size (KB) = 64
[LFS] LittleFS Mount Fail
[LFS] Formatting... 

So same behaviour for every Example "LittleFS Mount Fail"

Here is my config:

I install the Arduino Mbed OS Nano Boards (v2.4.1) :

I installed the following Arduino libraries:

The selected Board is the Arduino Mbed OS Nano Boards-->Arduino Nano RP2040 Connect (as the official Arduino install instructions for this board type suggest)

Then I updated the Firmware to version: NINA firmware (1.4.8) (Arduino Nano RP2040 Connect)

I installed the following Arduino libraries:

and

I use the newest Arduino IDE (hourly build from yesterday) - but also the official release Arduino IDE 1.8.16 does not work.

Below are images of the old purchase board and one image of the new batch of boards. They are in a terrible state ! (and I already complained at the official Arduino Store to sell such awfully looking boards). The RP2040 is supposed to be a shiny example of IOT !

First the 2-month old working board:

And here one of the 8 awfully looking new boards that do not work !

I've got a board with the adesto flash and the example sketch of LittleFS_Mbed_RP2040 library is failing with an mbedOS Hard Fault. It's likely a software issue, but need some time to investigate.

@iKK001 i'va made a couple of test and found out that the example is working with core 2.3.1 Could you plese give it a try on your board?

You can easily downgrade the core from the IDE

Nice finding, and Yes, I will make the tests tonight (> 20:00h - since no time before that). I will get back to you as soon as have it running with 2.3.1 core, ok?

@pennam : Thank you very much Mattia, for your finding!

As for my "faulty boards", the WiFiManager_NINA_Lite is now working with the older mbed-core version 2.3.1.

I first de-installed the version 2.4.1 with the Board-Manager in the Arduino-IDE.

And then I installed the previous version 2.3.1 - and now everything works again !

Starting the WiFiManager_NINA_Lite, I now get the correct terminal printout as follows:

LittleFS size (KB) = 64
LittleFS Mount OK
LittleFS Flag read = 0xd0d04321

Do you know where to address this issue with the newest board version 2.4.1 ??

@iKK001 Thanks for testing this on your boards. Don't know yet which is the root cause of the issue, but we will take care of it. I will update this issue as soon as i have a solution.
