Linux Embedded specialist of Petalinux 2019.2, ARM and Xilinx architectures

Hi

I'm new to Linux Embedded environment and looking for a specialist in ARM and petalinux environment who able to support and guide me when I need some help (like now) or some theoretical / technical questions will popped up. This session is going to be for at least a few months, so I’d like to share with you one of my challenges and see if its fit to you.

My current project: Bringing up on my custom board a Linux Image, my custom board very similar to the ZCU 106 Ultrascale+ MPSoC board.

What I've already achieved:

I’ve generated the [login to view URL] which contains: fsbl, uboot, bl31, pmufw, [login to view URL], u-boot and image.ub.

When I program the flash with this [login to view URL] the [login to view URL] start running, but than an Error occurred:

[ 4.421147] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

seems that kernel doesn't find the rootfs.. any ideas? I work thru QSPI flash only.

Extra Info:

1. My costumed board is working properly and there is no any HW issue since I'm able to run on it a vxWorks 7 image.

2. I use petalinux 2019.2 version and Vitis 2019.2

3. I use the Xilinx tool: Platform Cable USB II for programming and debug.

But please! I’d like to get bids just from a fellows who has a strong knowledge and experience with such a technology: Yocto project, Xilinx boards, petalinux 2019.2 and Platform Cable USB II.

If you think you can help me and you are available for this mission in the next few days - I'd like to hear from you.

Thanks!
