my borad base on imx6qsabrelite

it work well with 1GB ram.

now i want to check it's performance with 512MB.

so i set the RAM size to 512MB in dtb and uboot(physical memory is 1GB in fact),

but kernel boot will hang at :writel_relaxed(1 << CCM_CCGR_OFFSET(0), base + 0x7c);

this can reproduce very boot.

is there someone have any idear ?

Hi,

Iam also working on a board with 512MB and facing the same issue that it is getting stucked at:

writel_relaxed(1 << CCM_CCGR_OFFSET(0), base + 0x7c);

    writel_relaxed(0, base + 0x80);

Can you give me some idea, how you have resolved this issue with 512M. Please help..

Hi hu

reason may be insufficient memory, one can try core-image-minimal

O.S. Systems

or for example decrease cma:

imx_v7_defconfig <---- change CONFIG_CMA_SIZE_MBYTES size

Best regards

igor

Hi Igorpadykov:

thanks for your reply.

you are right. my CONFIG_CMA_SIZE_MBYTES reserved 256M memory.

after set it to 0, now my board can work well with 540M memory, by set mem=540M in cmdline.

but kernel still hang with 512M memory. i think maybe there is something esle reserved memory

as CONFIG_CMA_SIZE_MBYTES. now i will try to find it out.

also i will take try core-image-minimal as you suggest.
