Debug probe ethernet connection

Catherine — Mon, 24 Feb 2025 01:59:07 GMT

Hi expert,

Customer is using S32DS on physical ubuntu 22.04, and found problems on connecting the debug probe. Here is the screenshot.

It seems that there is something error in connecting by the usb. So my question is

(1) Is it an issue of connecting usb? If yes, how to solve this issue?

(2)Is there any hands-on tutorial of connecting debug probe by ethernet?

Hi,

with older probes on some PCs is issue with the USB - the USB on older probes acts as Ethernet over USB and in some cases OS can't handle it.

To use debug probe with Ethernet connection you can simply connect probe to network with DHCP server and use probe's domain name (or assigned IP address). If you need static IP for probe (for example with missing DHCP server) you can use this HOWTO document - https://community.nxp.com/t5/S32-Design-Studio-Knowledge-Base/HOWTO-Setup-static-IP-address-for-S32-debug-probe/ta-p/1103006

It depends what's the cause. Most usually is the reason that OS security settings (like our NXP PC Image) allows only one ethernet connection and OS disable second Eth - which is Debug Probe's Ethernet over USB interface.

It may be also some driver issue (but in this case it looks that driver is okay), user privileges issue - can user access /dev/ttyACM0 device?

I suggest to focus on OS settings.
