I'm using an iMX6 sabreSD board, SCH-27516 Rev B5, 700-27516 Rev X5

  • sabreSD board boots fine with NXP i.MX Release Distro 4.14-sumo (sumo)
  • The issue is when loaded with Kernel v4.19 (warrior release) and the latest release, NXP i.MX Release Distro 5.4-zeus (zeus)! L5.4.3_1.0.0_MX6QDLSOLOX, the kernel goes to panic, see below logs.

 

Supposedly, this is a memory issue only appears on older sabreSD boards, kindly point to some solution to run the latest kernel on older board revisions, also mention board revisions which are currently supported by NXP to run the latest sources.
