LPC55S69 - nxpdebugmbox crashes on Ubuntu 20.04

[elibenami]

Hi,

An attempt to connect to with nxpdebugmbox ends with segmentation fault.

My system:
- Ubuntu 20.04 LTS
- MCUXpresson IDE v 11.40 (mcuxpressoide-11.4.0_6224.x86_64.deb)
- spsdk, version 1.4.0.post2
- LPCXpresso EVK rev 2a

Following execution of nxpdebugmbox, my LPCXpresso EVK board is successfully identified and I am able to select it from the textual menu.

However, following that the execution ends with segmentation fault (core dump).

On Ubuntu 16.04/18.04, nxpdebugmbox does not even reach to that point and ends with python errors.

Here is my exection log from Ubuntu:

Has anyone encountered this issue?

Many thanks,

Hello Elija,

How about this issue now? 

How about change to another usb and USB line.
