"Unable to load libusb0.dll" with MCUXpresso GUI Flash Tool using P&E Micro Multilink Universal

[rvigneault]

Hi!

I am currently successfully running my (Debug and Release) applications using "Debug Configurations..." but now I only want to flash the image on my board and it does not work.

I am using a PE Micro Multilink Universal with MCUXpresso IDE v11.6.1 on Windows 10 to debug and flash.

When clicking the "GUI Flash Tool" icon, I get the following window, where I select the .axf file for the image to flash. I then click "Run..."

I end up in the "Probes discovered" window, where I click "OK", which leads me to a prompt telling me that the operation succeeded.

But nothing happens on the board, and when I look at the "GUI Flash Tool console for PE Micro probes", I get this output:

I made a diff of this output with the one of a collegue for which it worked and saw that the following lines are only in my log:

Unable to load libusb0.dll

I updated "GNU ARM PEMicro Interface Debugging Support" and even uninstalled and reinstalled MCUXpresso but neither did help.

Any ideas on what the problem could be and how to fix it?

Thanks!

Just to keep this ticket updated, I don't know why but now it works.

There has been many Windows 10 and MCUXpresso SDK updates in the mean time, I guess it might have fix a setup error in my environment.

Hi @rvigneault ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To be prudent, I'd like to know the platform you tested with, further, does a similar error still happen when you try other debug tools?
Have a great day,
TIC

Hi @jeremyzhou !

The microcontroller we are using is the NXP MIMXRT1024CAG4A.

It is worth confirmation but I don't think that it should be a problem since some colleagues have the exact same setup (same MCU, same debug tool and same MCUXpresso version) but are not getting the "Unable to load libusb0.dll" log and are able to flash the MCU using the GUI Flash Tool.

Thanks!

Hi @rvigneault ，
Thanks for your reply.
Today, I try the exact same testing as you did, but I don't encounter the error you mentioned above.

Note: MCUXpresso IDE is v11.6.0
Have a great day,

Hi @jeremyzhou ,

Thanks for the attempt. You probably have the same output than my colleagues then...

I there anything I can do to give more useful information to locate the problem?

Do you know what libusb0.dll is, what it is used by and how it should be installed or found with/by MCUXpresso?

Thanks for your help!

[jeremyzhou]

Hi @rvigneault ,
1) Do you know what libusb0.dll is, what it is used by and how it should be installed or found with/by MCUXpresso?
-- No, I've not encountered the issue, however, I find the missing libusb0.dll seems to be a common issue in Windows, maybe you can try the method in the post, or search more ways via Google.
Have a great day,
TIC
