Yocto Kernel 3.10.17 bad CRC

[vasileiostzizil]

Hello all

I am trying to load the yocto with the kernel 3.10.17 through the sdcard.

I followed the instructions and through the dd command I wrote the image to the card.

The sambresd imx6 starts but after some seconds I am getting the message Kernel ... bad CRC and then it gets me to the Uboot console.

If there any isssue with that kernel?

Thank you

Vasilis

Probably you need check the u-boot parameters, the ones listed in the section 8.2 of the user guide document is somehow wrong. I can boot the device by making the following changes:

• "root=/dev/mmcblk0p2"  should be "root=/dev/mmcblk0p1" in my case since the guide only created one partition on the SD card;
• "mmc read ${loadaddr} 0x800 0x2000" should be "mmc read ${loadaddr} 0x800 0x4000" actually since 0x800000bytes means 0x4000 blocks if each block has 0x200 (512) bytes

Please try it and let me know if this helps.

vasileiostzizilonis problem has been solved already. It was the uSD card or card adapter.

Usually this type of error is a bad uSD card or card adapter.
