MCU-LINK Debug Probe

Hi ,

I have a MCU-LINK which i have used with windows, recently i switched to Ubuntu and after installing the MCUXpreesso ide (mcuxpressoide-11.5.0_7232.x86_64.deb , MCUXpresso IDE v11.5.0 [Build 7232] [2022-01-11]) and MCU-LINK (MCU-LINK_installer_2.250_Linux).

MCUXpresso IDE (redlinkserv) can not detect the probes.

The redlinkserv starts normally, and i killed redlinkserv after each try.

The MCU LINK gets detected bu the OS :

I have tried to update firmware on MCU LINK. Reinstalled MCUXpresso IDE and MCU LINK software.

Regards,

Hi @4Rawi :

- Can you tell us more details about this problem?

- which version of Linux are you having a problem with?

-did you see some errors when you connect the mcu-link in your dmesg terminal?

-Are you virtualizing Linux on some program like Virtual Box or VMWare? or you have a Linux as a system base of your machine?

Regards

Windows is sloppy compared to Linux.
Linux may care about the bad packet size in the descriptor for endpoint 5.

The not enough bandwidth message could be related to that, or that hub is out of capacity.
Are there different results if move to a different USB port on a different hub?

Hi @bobpaddock ,

I got the same issue when i plugg MCU-Link directly on the Laptop USB ports.

After some investigation, plugging out all USB devices from the Laptop, the machine finally enumerated MCU-Link.

When i tried to plug in keyboard and mouse while observing the syslog i saw that it could not enumerate the last USB device plugged, with that it showed that it is a kernel issue and not the MCU-Link issue.

Thank you for your help!

Hi @bobpaddock and @CarlosGarabito ,

I have inestigated further and have some other findings:

I am using Lenovo Docking. The docking station works fine with other USB devices i have but when MCU-Link come into the picture the troubles begins. The MCU-Link (Specifically, SWD) is reporting an invalid endpoint buffer size (See sudo dmesg -T image ). with that, i am not able to use more than ONE USB device plugged into the Docking station.

I changed the Docking station with one similar, i got the same error.

When i disables SWD on MCU-Link (everything works fine but i am not able to MCU-Link as a debugger probe).

Could you please help with that?

Regards,
