Hi

Planning to implement firmware upgrade for M4 Core . Is there any method to keep two M4 images in eMMC (one is factory image) and change boot location to factory image from A35 Linux when the current image fails.i.Mx8QXPlus M4 image is starting before uboot.

Thanks

Hi Jithesh

 

unfortunately I am not aware of such special procedures, in general one can look at

sect.5.8.2.2.1 High Level eMMC Boot Flow  i.MX 8DualXPlus/8QuadXPlus Applications Processor Reference Manual

 

Best regards
