Increasing CMA in imx6dq scm

[zafriry]

Hi,

I am using the SCM-i.MX 6Quad (imx6dqscm-1gb-qwks board), I am trying to increase the CMA (Contiguous Memory Allocator) from the default of 320 to something bigger, say CONFIG_CMA_SIZE_MBYTES=640.

To to this, I did the following:

1. In the .config (menuconfig) changed the CONFIG_CMA_SIZE_MBYTES=350 to CONFIG_CMA_SIZE_MBYTES=640

2. in /include/configs/mx6sabre_common.h, added cma=640M to bootargs. by applying this patch:

---
index 424189a..f59e8e1 100644
--- a/include/configs/mx6sabre_common.h
+++ b/include/configs/mx6sabre_common.h

-        "root=${mmcroot} ${dmfc} \0" \
+       "root=${mmcroot} ${dmfc} cma=640M \0" \  
--
1.9.1

3. In the dts of the image, I applied the interleaving address, this was based on the imx6dqscm-1gb-interleave.dts ( did not see any difference between :

/ {
    memory: memory {
        linux,usable-memory = <0x10000000 0x40000000>;
    };

};

4. I am using a quick start board, so I modified the BOOT_CFG pads to boot up in interleave mode

           1                                                  8

SW1: ON OFF ON OFF ON OFF OFF ON

After doing these, the board boots up but stops while starting up the Linux OS.

Here is the output after the u-boot:

At this point the boot stops.

Am I missing something? Has anyone been successful in increasing the CMA on this board?

Any help will be appreciated.

Thanks,

HI Zeph

boot may stop due to non-existing drivers or peripherals, like (from log):

sema4,rpmsg,mcc drivers - these only for i.MX6SX, not for i.MX6DQ
mag3110, IR NEC and other IR** drivers - do you have these real sensors

attached to board

One can try fresh build from scratch using below official patch,

starting from minimal configuration:
