Uncompressing Linux... done, booting the kernel. stoped after this.

I am trying to boot the kernel through sd card, and sticking into following problem:

MX6Q CAMARO U-Boot > source boot

is there any mistake in u-boot environment setting, or something else??

Hi Sagar

Uncompressing Linux... hanging may mean ddr errors, so one can try ddr test

https://community.freescale.com/docs/DOC-105652

and rebuild uboot with new calibration coefficients placed in uboot/../mx6qsabresd/*.cfg file.

Best regards
igor
