Hi Team
We made one customized board based on imx6 solo, when we are trying to flash pre-built yacto image available online (Nxp website ) very first time in bare board through mfgtool it is getting stuck after loading uboot and kernel with message " flashing os image "
Please help to understand following
1) Does DDR stress toll should be run before mfgtool or after flashing image ?
2 ) Does mfgtool will store images in RAM of processor or eMMC/SD
card?
3) Which clock source will be used for this process, external crystal / internal?
4)How i should proceed for debugging if problem exist in DDR3 or eMMC?
basically i don't have proper understanding of complete flow of process?
Regards,

1) DDR stress tool is a calibration tool which is used to check DDR performance. It is not dependent on mfgtool, you can use it before or after flashing image . As your custom board , you can run the DDR stress tool for checking DDR performance after that you can flash the image using mfgtool.
2)The mfgtool stores the image in eMMC/SD . This you can verify from Profile/linux/Os firmware/ucl2.xml file.

Hi Karan
Thanks for update .
Basically we are trying to upload image in SD card through MFGTOOL by putting in serial download mode .But can't succeed.
During process it load initramfs , then loads uboot, after that it stuck . When i am checking sd card manually i can't see uboot inside .
Does it loads initramfs and uboot inside internal RAM / external DDR3 / SD card ?
2) What could be possible reasons for hanging at programming OS.
3) Please let us know which document i can refer to have details about MFGTOOLS, so that i caould have understaning how it works ?
