Linux Embedded specialist of Petalinux 2019.2, ARM and Xilinx architectures
Budget: $25 – $50 USD
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 BOOT.BIN which contains: fsbl, uboot, bl31, pmufw, system.bit, u-boot and image.ub.
When I program the flash with this BOOT.BIN the image.ub start running, but than an Error occurred:

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!
