i.MX6 Solo 256MB ram - Unable to allocate framebuffer memory

[marconnl]

Hi all,

Im trying to get the core-image-sato to work on a (Seco) i.MX6 Solo with 256MB ram with a 480x272 LCD touchscreen. Linux boots succesful and during boot I see a little pinguin in the left top corner of my screen and after that a Yocto loading screen. But when Xorg starts I get the follow error:

[    8.724708] mxc_sdc_fb fb.18: Unable to allocate framebuffer memory
[    8.724715] detected fb_set_par error, error code: -12

Why does it fail to allocate framebuffer memory?

Below my kernel boot log.

Thank you for any help regarding this issue!

[marconnl · Accepted solution]

I have solved my framebuffer memory issue. And in case anyone else runs into this problem here's how I solved the memory issue.

By default the GPU driver reserves 132MB. With only 256MB ram this is a whole lot and didn't leave enough left over for the framebuffer.

To solve this issue I have changed the value in gc_hal_kernel_platform_imx6q14.config to 32MB. Now my imx runs fine with my 4.3" and 10.1" LCDs with resolutions of 480x272 & 1280x800.

Hi Marco

one can try to run core-image-minimal image to test if this is caused by

insufficient memory. In general it can be debugged in

linux/drivers/video/fbdev/mxc/mxc_ipuv3_fb.c
function mxcfb_map_video_memory(), which allocates the DRAM memory for the frame buffer

use AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors
