Hai
we have a custom board same as iMX6SLEVK.
we downloaded Yocto 4.1.15 and compiled fsl-image-gui.
Then by using Mfgtools flashed compiled fsl-image-gui images to sdcard successfully.
But at the booting time it is getting stop at "cpu cpu0: dev_pm_opp_get_opp_count: device OPP not found (-19)" without any errors.
if we use the same sdcard in iMX6SLEVK it is booting properly.
when we compare custom board & iMX6SLEVK logs "cpu cpu0: dev_pm_opp_get_opp_count: device OPP not found (-19)" is coming in both of the logs.
for reference we attached custom board logs and iMX6SLEVK logs .
Thanks & Regards,
D.Jansirani

Hi Jansi
behaviour is correct as "same sdcard" works for iMX6SLEVK but may not work
for new board, so ddr test should be run and new calibration coefficients
should be entered to uboot *.cfg file, then build new image for custom board
uboot-imx.git - Freescale i.MX u-boot Tree

Thanks for the reply,
But we already tested Marshmallo Demo images in our custom board ,board is booting properly.
But Yocto4.1.15 is not booting.
if it is a ddr problem Marshmallo also should not boot in our custom board .
is this correct or not?
So you did not tested memory with ddr test ?
I do not think that this is right.
In general one can debug it using apnote AN4553 Using Open Source Debugging
Tools for Linux on i.MX Processors
