VIM3 and VIM3L start from revision v14 have another DRAM configuration.

Some images and OS distros still can use old boot-loaders blobs which not compatible with new hardware revisions v14.

Solution:

• rewrite/update boot-loader
• 

This can get after writing old images into internal eMMC storage for new board rev v14

In this situation easiest way is re-flash device by right image for restore it.
