The petalinux-util --jtag-logbuf command logs the Linux kernel printk output buffer that occurs when booting a Linux kernel image using JTAG. This workflow is intended for debugging the Linux kernel for review and debug. This workflow can be useful when the Linux kernel is not producing output using a serial terminal. For details on how to boot a system using JTAG, see the petalinux-boot --jtag command. For MicroBlaze™ CPUs, the image that can be debugged is <plnx-proj-root>/image/linux/image.elf. For Arm® cores, the image that can be debugged is <plnx-proj-root>/image/linux/vmlinux.
