Can anyone help me to resolve this?Its urgent!

Note:  I tried with MFG tools and gets  otg works for loading u-boot and other binaries to ram . Its just mfgtool after "Jumping to OS" it stays at No Device connected"so tried using fsl-sd-card-partition.sh.

Thanks,

Richu

Hi igor,

Thanks for your prompt reply.

Actually the board was booting  with out any issues with the same images in another sd card.Unfortunately i lost that sd card and brought another sd card.

• Boot hangs after "random: crng init done"(log attached above) what that line means.
• Is there any difference in flashing using MFG tool and fsl-sd-card-partition.sh script(attached above).
• Is there any changes has to be done in fsl-sd-card-partion.sh

working sd card log

new sd card log

both are part of logs of two sd cards(full log is attached along with this)

as you can see filesystem is not getting mounted in mmcblk2p5 in new sd card.

Is that flashed properly??

Please help me to resolve?

Thanks,

Richu

Hi Richu

one can try with other sd cards, preferably brand new.

Best regards

Hi igor,

I finally got this work when execute commands in fsl-csrd-partition.sh manually.

Hi Richu,

I am also facing the same issue now, executing the script commands manually means do we need to partition the sd card manually using the gdisk command and copy the respective files to the sd card partitions?

Regards,

Parvathi.

Hi RICHU

one can try to run latest ddr test

i.MX6/7 DDR Stress Test Tool V3.00 

and rebuild image with updated ddr calibration coefficients found from ddr test

in uboot ..freescale/mx7dsabresd/*.cfg file

Best regards
igor
