I'm using an imx6sl-evk board with 512 MB lpddr2 som, I use yocto bsp and I've compiled and flashed the images successfully however on booting the kernel hangs at:
Console: switching to colour frame buffer device 30x40
on proper booting the next line is supposed to read
mxsfb 20f8000.lcdif: initialized
but the kernel just hangs on the previous line, what changes do I need to make to kernel source to have it boot correctly?
I've attached the log of the non working board and another log of a board that boots fine but has 1GB DRAM
Solved! Go to Solution.
Hi Sujay
for 512MB one can try to change cma size as in example
imx6ull-9x9-evk.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
also check if lcdif clock is enabled by register CCM CCM_CCGR3.
Best regards

Thanks for the reply igor,
The issue was solved by commenting the function
ret = mxsfb_overlay_map_video_memory(fbi, ofb);
