We are running a project with two systems based on i.MX6Q, i.e. two CPUs, two PMICs, eight DDRs...and etc. The two systems are separated and can communicate via USB and UART, power input SYS_4V2 is common for both.
All power rails are checked OK, but when we try to download image by using MfgTool, after process "Jumping to OS image", the tool stops and never steps over.
I doubt this is DDR issue but this portion is the same as FSL EVB, and has been verified on other single system projects. We've tried to use TF card boot with specific image and settings, it failed neither.
Does anyone has some experience on this symptom?
