Arduino MKR Vidor4000 problems!!!!

try plugging in a lipo battery to its battery port. it might be that your usb port is providing insufficient power to power up the board

Hi Robert,

All that seemed to make sense and I couldn't see anything in your printout to argue that.

I plugged my Vidor 4000 into my USB and ran up the IDE (installed version) and got identical print out to yourself (albeit with a very slightly different flash time) and the LED did indeed blink. You could try weiwei2 point and try a LiPo or plug the USB into a quality USB charger to see if that is the problem.

Please let us know how you get on.

Although this post is over a month old, if you are running with the Desktop version of the Arduino IDE, I would suggest using the latest Hourly Build of the Arduino IDE instead of the current released one.

You can get the hourly build part way down the page on the following link:

https://www.arduino.cc/en/Main/Software

There may be a firmware update for the board as well so you might want to look at that.

Under File->Preferences on the Arduino IDE you can enable "Show verbose output during: upload and compilation.  This should give you more details and may point to an issue.

After the CPU reset, the next phase should have been a Read back but from what is posted that does not seem to happen.  I wonder if the board is going offline after the Write so it can't do a read back.  Have you tried resetting the board from the reset button to see if the Sketch runs after manual reset?  You could try to reset the board by pressing the Reset button and then applying power to it.

The Blink Sketch should blink the LED_BUILTIN, so if that is not set in your Sketch, then use that instead of any other defined pin.

Hello,

I see that it is an old post but I'm running in the same trouble, my MKR4000 boards (3 different boards) are all running much slower than my MKR1010 with the same code !?!  Why ...?

No idea yet - I'm comparing the startup.c files and the other places where clocks are configured but I still cannot find the root cause...

... if somebody solved this issue ?

Thanks, Jean

Could you attach a zip file of the code in question? Just a footnote, looking at https://hackaday.com/2018/07/30/hands-on-with-new-arduino-fpga-board-mkr-vidor-4000/  it would seem the hardware may be interesting. The support in software though lacks any polish or a good following.4452.contentimage_53.png

Have you updated the firmware on the board via the Arduino IDE yet?  I would suggest using the latest or the hourly build of the Arduino IDe to ensure you have the latest code for the board.

Example(see Update MKR WiFi 1010 Firmware. Should be the same for the MKR Vidor 4000):

Update the bootloader (See BootLoader):

Also, have you posted this on the Arduino forums.  I would suspect that would be your best best for Arduino support.

https://forum.arduino.cc/index.php?PHPSESSID=5b92peas320gpb4ulggfje1tk0&board=125.0

I found that the speed trouble comes from 'print.client(data);' => sending 'big' chunk of data (~ 1.3 kB)  to the WiFiNINA module takes much much longer on the MKR4000 than on the MKR1010

If I check the firmware version it says that I use 1.1.0 and I should upgrade to 1.2.0 but where is version 1.2.0 ?!

Not in stable 1.8.10, not in the beta and not in the latest hourly build !?! Only 1.1.0 available...

This issue was filed against WiFiNINNA mid last year by me and someone else but it looks like it was closed with no resolution.

Perhaps you would have better luck with the Arduino folks, but it does seem like they are not really interested in providing much support for this board.

According to Arduino, look at https://www.arduino.cc/en/Reference/WiFiNINA .

Utilities

You find these two utilities under Examples - > WiFiNINA -> Tools.

• CheckWiFiNINAFirmwareVersion : Reads the required firmware number required from library and matches with the one installed on the board or the shield.
• WiFiNINAFirmwareUpdater : The sketch that must be loaded to allow the firmware and certificates update process through the integrated plugin of Arduino Software (IDE) rel. 1.8.5 or later.

Can you find WiDiNINAFirmawareUpdater? Note IDE must be 1.8.5 or later.

Oh maybe the later versions is not working. Save off your working one and install a back level version. I have heard upgrades may drop function or introduce new problems...
