We have iMX6 Solo board designed based on SABRESD design. We ported Linux Yocto Morty and working as expected. We also ported Yocto ‘Rocko’ build but supported kernel version looks quite old (kernel 4.1). As per FSL Community release document 2.4 Rocko, it seems SABRESD board is not supported. Due to this we cannot upgrade to Chromium 67 for Rocko build with HW acceleration support.
Note – On Morty build, Chromium 52 is working as expected with HW acceleration.
