Hello
I change from MQX 4.1 to MQX 4.2. But now I have trouble with the usb communication or the mfs access. At the beginning, when the function usb_msd_install() was performed, I get a unhandled interrupt. The attach and detach event was recogniced, but after the usb_msd_install() was called the unhandled interrupt stop the task. Then I changed the configuration from MQX 4.2, that it's identical with my configuration in MQX 4.1. Now the connection to the usb-stick works, but as soon as I execute a command to the USB-stick, I get the unhandled interrupt. I adapt the source-code for the change in MQX 4.2.
Has anyone an idea whats going wrong or what cause the unhandled interrupt?
Thanks
Hi Patric,
Have you solved this issue?

Hi Isaac
I had holiday and had first to work on a other project. I tried it with different types of usb-sticks. I still have the problem. I tried to adopt the source from the usb_mfs example. But I still get the unhandled interrupt. I now ordered a tower system to try the example on the tower and from there to try it on our design.
Do you have any idea what's could cause the unhandled interrupt?
Hi Patrick,
When i reviewed your code, it wasn't migrated complete and a NULL pointer was passed to a function, so it causes the unhandled interrupt. Could you please review this point? (You can check the Service Request you created and where this point was sent to you).

Hello Patric
Are you still having this issue?

Dear Patrick,
Does USB-stick works well in MQX 4.0? Because there is some USB-sticks that does not meet MSD specification and could fail.
