Try using it as gpio. Export it, set as input direction and check it's value when pressed to see if it actualy works before using with generic-uio

When u-boot tries to load image.ub the following error ocurs
Verifying Checksum ... Bad Data CRC
Ramdisk image is corrupt or invalidAfter that it tries to boot over network thus the other errors.
Make sure to regenerate image.ub and retry.

Hi @amd,
If you just want to load a bitstream at boot time then a BOOT.BIN file containing fsbl and bitstream It is sufficient. you can use Xilinx bootgen tool for that. https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841976/Prepare+boot+image
On SD card make sure to use FAT32 for first partition where BOOT.BIN is placed. https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841655/Prepare+Boot+Medium
Otherwise:
1. Config files for PYNQ-Z1 board are added by patch files that can be found in https://github.com/Xilinx/PYNQ/tree/master/boards/Pynq-Z1/petalinux_bsp/meta-user/recipes-bsp/u-boot directory2. By applying the patches found in above directory.
3. PYNQ build system uses petalinux internally which in turn requires Xilinx bootgen tool to generate the BOOT.BIN. ($ petalinux-package --boot --u-boot --fpga --fsbl --force)
This file contains:
a. fsbl;
b. bitstream.bin;
c. u-boot; (this u-boot contains a dtb)
To boot the board up to second stage bootlader[ssbl](u-boot) you need BOOT.BIN and boot.scr|uEnv.txt (I am guessing it is optional for only this however u-boot needs a boot script|environment)
The boot flow is as follows:
A. zsbl searches for BOOT.BIN from which fsbl is loaded and run.
B. After that fsbl will load the bitstream (found in BOOT.BIN) [Also this step can be performed by u-boot; command `fpga` is required for this]
If it fails throws a short error message on UART(when you build the fsbl you can add the debug flag for more output.)
C. In the end u-boot(found in BOOT.BIN) is loaded and started: u-boot prompt is available on UART.
Using petailnux to build all this is way more easy but it depends on what you want to accomplish. If you still want to run the PYNQ OS|distribution in the end or you just want to use the board for stand alone application.So if you manually compile u-boot then make sure the fsbl is actually working if included in BOOT.bin

Seams like you sysroot is missing some files
How was the sysroot generated?run following command in sysroot directory and check if the file is really missing : find ./ -iname "crtbeginS.o"

XC7Z007S has only one core however in your device tree there is a node for a second core "cpu1". File pcw.dts enables nodes in reference zynq dtsi. Also make sure in your user-system.dtsi file there are no references to cpu1 node.

What dmesg says on your laptop when you power the board with usb pluged in ?
You can run "dmeg -w" on your laptop to watch kernel messages as you power on the board.
-
Not sure what else is stated in the context of the quoted text but it looks like it is about a kernel module which can be included in petalinux by 1) configuring the kernel if the module is already included in the kernel sources. 2) patch and configure the kernel if not. 3) create a petalinux (yocto) recipe* for building the respective module out of tree then add it to the rootfs.
*This recipe may already exist.
It is possible other software are reqired for the final image to properly work with matlab.

If you want to use version 2022.1 of petalinux/vivado you should know there is no bsp yet.
However it is not that hard to create a basic design in vivado then create a petalinux project using zynq template acording to ug1144. Import your hardware design(.xsa file) using petalinux configure command.
board specific configurations can be found for erliear versions of vivado/petalinux here: https://github.com/Digilent/Zybo-Z7-OS you can use branch 20/Petalinux/next (petalinux 2020.1) as a reference.
-
Check this https://github.com/Digilent/Zybo-Z7-OS and try branch 20/Petalinux/next.
If you choose to use this updated version then after a succesful build you can replace hardware desciption with yours also make sure to change the device tree to match your design.
-
It is an old build. The source branch history was changed. You can check for that specific commits on other branches and fix the recipes to point to new branch. You may also like to take a look at this repository https://github.com/Digilent/Cora-Z7-OS.

For a quick test you can use the sdcard. Place boot.bin, boot.scr and image.ub files on the sdcard and set bootmode to sdcard (not jtag).Then watch the boot process on serial port(UART over USB).
boot.bin file can be generated using petalinux-package command. Check command output to be sure bitstream(.bit) file is included. "petalinux-package --boot --u-boot --fpga --fsbl" Check ug1144 for more details on petalinux.
Regarding your test for booting using jtag/debug mode, did you reached step 10.4 bulet point 5 where you stop boot process by pressing Enter key on serial console(not the xsct console)?
QuoteI expect to see the u-boot menu on my console (zedboard USB console port), but don't. I don't see anything ever on my console.
As mention in instructions [10.4 bulet point4] on serial(usb) console you will receive a message to press a key to stop the boot process. By doing this you can reach u-boot CLI. At this point in xsct console you are instructed to suspend the boot process load image.ub file in RAM the resume the u-boot process and run a boot command to continue into next boot stage: loading linux kernel, device tree,rootfs etc..Q1: It shoud be ok for this test.
Q2: It should just work no chages are needed.
There are two parts at work: board UART over USB and your tool/software that conects to the UART(serial) [I personaly use picocom].There are some software that do not work as expected for example you can not send but you can receive. In short you should know your tool.
Q3.a:It's ok.
Q3.b: u-boot can be dependent on the bitstream (bitstream == hardware) . Bitstream should be loaded since it is part of the hardware(Step 8). Anything else at the apropiate time.
Q4: No. bootm command is suficient to use image.ub you loaded in RAM at step 10.4. Bulet point 7.

The binary files is temporarily stored in <proj-dir>/build/tmp/work/<arch>/<app-name>/build
to have access to it you should run petalinux-build -c <app-name> -x compile -
`system-user.dtsi` is used to extend/overwrite device tree nodes generated by petalinux. For this file to be almost empty it is expected in this case.

The user guide(UG1144) for petaliunx is a good starting point. And start with creating a new project. Also this may help https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842250/PetaLinux
Or using this project for ZedBoard. However since you have a custom IP you may need to change various aspects of the project like the device tree and creating a custom kernel driver for your IP or a using uio for a driver in user-space.
-
Please use petalinux/yocto to build the kernel.
Additionally if you intend to manually build kernel you can use this instructions for reference. -
@Gumesh
You may want to take a look at this projectVivado 2020.1 project for Zybo-z7-20 https://github.com/Digilent/Zybo-Z7-HW/tree/20/Petalinux%2Fnext
Petalinux 2020.1 project https://github.com/Digilent/Zybo-Z7-OS/tree/20/Petalinux%2Fnext
Currently there is work done to port to Vivado and petaliunx 2021.1
In newer version the xilinx linux kernel (5.4 for petalinux 2020.1 and 5.10 for petaliunx 2021.1) is used instead of digilent linux kernel. -
@Mikek
Have you tried a different terminal ? for instance teraterm ?
Or in linux something like picocom?

Probably term `functions` is misleading it should be commands.
Petalinux 2020.2 - how to include other components/yocto/layers
in Embedded Linux

There are recipes that have unmet dependencies/requirements which can lead to build problems. That is why not all recipes listed by `bitbake-layers show-recipes` are included in `project-spec/configs/rootfs_config` and need to be added via `project-spec/meta-user/conf/user-rootfsconfig`
You can try adding package groups however in this situation you can not enable only one package in a package group.
