Hi We are using the iMx6ULL IT 512M DDR 512M Flash Col on Volia EVK.
Following Yocto build instructions on your site (with latest v5 BSP) and using EasyInstaller to write the image I get the following Kernel crash.
Is there issue with this latest BSP?
Using Toradex build of latest console image things boot fine.
