Recently updated the Drive OS from 5.1.6 to 5.2.6. directly connecting the LAN connection to 1000BASE-T1 some LAN connection(1000MBbs) working and some not(100MBbs link speed). In host machine both connections work. and previous version (5.1.6) both connections works. In Host machine LAN connection which works on the 1000BASE-T1 shows link speed as 10000(MBbs) where as LAN connection which not working shows 100(MBbs) in the host machine. We like to use both connection can you give advice on that . Because of the when we connect the Velodyne lidar to 1000BASE-T1 that also not working . please help resolve this issue


Dear @balakrishnan.ayyanar,
Does that mean some of the HSD ports not working? Could you please share port details and pictures if possible for more clarity.

Dear @SivaRamaKrishnaNV

I am referring this port .

when i connect LAN cable in 1000MBbs link speed its working and 100MBbs is not working . But in 5.1.6 both are working

Dear @balakrishnan.ayyanar,
could you share the output of gethyperionconfig on aurix?

when i connect LAN cable in 1000MBbs link speed its working and 100MBbs is not working

Does that mean J9/J10 ports not working?

It is working if the link sped is 1000 Gb/s internet connection but not on Lidar sensor and 100Gbs link speed internet

Any update on this ?, even when i go back to the 5.1.6 same issue occurs

here is output of the gethyperionconfig. Ports are working , just that 100Mbs link speed is not supporting.

this are output of ethtool , might be helpful

Its very urgent , because of this our development suffer lot

As you can see from the figure , i am not using j9/j10. i want use the other (black one)

Dear @balakrishnan.ayyanar,
I tested internet connection by connecting 1&2 / 3&4 port. I expect Lidar to work when connecting to these ports. May I know how did you test lidar connection? Is it using DW sample?

Hi ,

I was checking with ROS velodyne drivers , It could not find the device . More importantly it was working before reflashing . Now Lidar connectio working on J11 (green ports ) not on the black ones


Dear @balakrishnan.ayyanar,
Does this still need support?

More importantly it was working before reflashing

What was the DRIVE OS version in working state?
