I've checked that I end-up with the same DTB as you sent me off-list for this configuration, so at least this part seems to work fine on my side. I also tried the imx_v6_v7_defconfig - based kernel on my board (obviously with my custom DTB), and the kernel still doesn't boot. Further, I've found that it's enough to disable CONFIG_REGULATOR_ANATOP in my custom kernel config to get kernel to see eMMC card, and then mount it as root file-system. I still fail to see what I do (or don't do) in my DTS (or kernel config) to confuse the kernel, and how to figure that out. Any ideas? -- Sergey Organov
