  • Not able to detect /dev/sda after root login

    I am working with the imx6q on a new customized board. However, it is pretty similar to the imx6q-sabresd development board.

    I've been able to configure a rocko image on the device but I am having trouble to define the nanoSSD on the dbt.

    When I boot the board the u-boot is able to recognize the SATA disk. However, after I register as boot I am not able to find /dev/sda (using fdisk -l).

    Do you know how can I configure this? It seems as if the disk it is not well defined at the kernel or at the dbt.

    Let me know if you have experience the same problem.

    PD: I have try with different boards and the result is the same. I have tested with a dizzy image as well and I was able to detect the disk. I am specifying all board pins as I did for dizzy.

    There may be many reasons and I am not expert for linux, but I would double check if all the pins are configured and initialized in linux correctly (including nano SSD reset signal if there is a separate reset for the chip). Also maybe some modules may need to be included in kernel (?)
