Re: [dpdk-ci] Upgraded DTS Version for NXP

[Brandon Lo <blo@iol.unh.edu>]

Hi everyone,


Has anybody got a chance to look at this issue?

I'm not sure if the NXP system specifically needs the DTS version from 
your local BitBucket repository. It seems that there are some obstacles 
that the original DTS repository is not able to deal with. Could 
somebody point me in the right direction to get this set up?


Thanks,

Brandon
