my custom board is based on sabresd board. use mfg tools to download firmware, and have errors when mfg linux write file to emmc.

my bsp version is L3.14.52. dcd table is updated by ddr tester. 

some console output is below, detail output is attached.


UTP: received command '$ echo 0 > /sys/block/mmcblk3boot0/force_ro'

UTP: executing "echo 0 > /sys/block/mmcblk3boot0/force_ro"

sh: /sys/block/mmcblk3boot0/force_ro: No such file or directory

UTP: sending Non-success to kernel for command $ echo 0 > /sys/block/mmcblk3boot0/force_ro.

add something about u-boot emmc result:

i use mfg tool to load u-boot only, and in u-boot cmd, type "mmc list" or "mmc dev 2" cmd, i got no vaild message. but when i change board the .cfg file from mx6qp.cfg to mx6q_4x_mt41j128.cfg, "mmc dev 2" cmd output some emmc info, although it's not correct info because the bus-width is 1 and capacity is 1k: . so i think something is wrong in dcd cfg file.

i modify mx6qp.cfg as this:run I.MX6DQSDL DDR3 Script Aid V0.10.xlsx, get an .inc file, and then use DDR_Tester.exe to test it, chage the leveling calibration,DQS Gating,Read&Write calibration to mx6qp.cfg file. there are many differences between .inc file and .cfg file, is it right only modify part of them?
