Issue to run Petalinux application - 2

[peterjohn]

Hi, 

I have some problem in the previous post and am not able to reply. 

Here is my script. When I run this script in XSCT, I get an error that petalinux commands are only supported in Linux platform. Therefore, I just source the tcl script.

# XSCT script for zybo-7z-20-project-1
# source C:/XilinxProjects/zybo-7z-20-project-1/scripts/xsct_tcl_petalinux_script.tcl
# petalinux-boot --jtag --prebuild 3 --tcl C:/XilinxProjects/zybo-7z-20-project-1/scripts/xsct_tcl_petalinux_script.tcl

The response from ZYBO is as under. It is not able to find or read the file “image.ub” although it is placed in the same directory. I am not sure why ZC702 is returned from ZYBO.

How to find and run the hello application ?

Hi @peterjohn 

Why don't you run "petalinux-boot --jtag --kernel" if you already have a petalinux project built at your end?

I need to run the script in XSCT in Vivado SDK in Windows 10 host operating system. I have transferred the petalinux image files (zynq_fsbl.elf, u-boot.elf, system.bit, image.ub) from virtual machine to host machine. The virtual machine has connectivity issue with FTDI USB to serial. It detect multiple serial ports for the connected board and also did not did the bit file although it as placed in the directory. 

Now I would like to boot petalinux from XSCT in Vivado SDK in Windows 10 host operating system. Can you please check my script and let me know the problem ? 

[stephenm]

You are loading the image.ub here

dow -data C:/XilinxProjects/zybo-7z-20-project-1/scripts/image.ub 0x10000000

However, is this the location uboot expects this image? I guess not.

Just stop in uboot and use the command below to boot

bootm 0x10000000

I have transferred all the boot image files (zynq_fsbl.elf, system.bit, u-boot-elf, image.ub) from the virtual machine to Window 10 host machine as I need to load the files through XSCT in Vivado SDK from Windows 10 host machine. I just have put all these files in the directory of existing hello world zynq program but i can be placed at some other location.

Here is my script. 

# XSCT script for zybo-7z-20-project-1
# source C:/XilinxProjects/zybo-7z-20-project-1/scripts/xsct_tcl_petalinux_script.tcl

I am not able to run the last command "bootm 0x10000000" in the tcl script. The command reply from TeraTerm is the same as in the earlier reply in this post. I have an application which I have included in the petalinux program. How to find the run the application through TeraTerm serial commands.

bootm is a uboot command:

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842223/U-boot

Boot uboot from jtag (remove the bootm command) and stop in uboot coomand prompt, and call the bootm command (bootm 0x10000000)

@stephenm 

Yes it works. I just run last command in serial terminal instead of XSCT. It ask me login and password in serial terminal TeraTerm. I also able to run my application under 

root@zynq-os:/usr/bin# 

Not sure how "Xilinx Zynq ZC702" returned from ZYBO. I have posted earlier.

@stephenm 

How to find the USB drive connected to ZYBO ? In which directory it is mounted ? 

[stephenm]

Ok, Great. Can you mark this as solved to help others.
