Curious about debugging those elusive Xilinx UltraScale+ MPSoC Linux boot errors? Dive into this post and uncover the secret behind the petalinux-boot "verbose" switch. Discover the nuances of identifying physical load addresses of each component as they're loaded, and the art of pairing it with insights from "readelf -l" and U-Boot's bdinfo. If you've ever been stumped by one component overwriting another, this is your guide to clarity. Equip yourself with the tools to troubleshoot with confidence!
Lets get into "Unraveling Xilinx UltraScale+ MPSoC Linux Boot Errors: A Deep Dive"
Environment
A PC connected to a ZCU102's USB-to-JTAG port.
2023.1 PetaLinux Tools and Vitis ( )
Ubuntu 22.04.01
PetaLinux Tools ZCU102 BSP xilinx-zcu102-v2023.1-05080224.bsp
Tools installed to ~/tools/amd/
Using the petalinux-boot --verbose Switch Output in xsct
By using petalinux-boot's "verbose" switch, saving the result, and running the output of the --verbose switch in xsct you'll see the physical load addresses of each component as those components are loaded. By pairing this with the MemSiz of each Segment listed via "readelf -l" and bdinfo from U-Boot, should boot get that far, a user can understand if one component overwrites another. If the boot fails to get to U-Boot, the script can be adjusted to "bisect the boot flow" running items up to the point of failure.
Note, you can more easily understand where things are in memory by converting hex addresses to human readable addresses using numfmt:
numfmt --to iec $(printf "%d\n" 0x87FFFFFFF)
34GVerbose petalinux-boot
petalinux-boot --jtag --fpga --kernel --hw_server-url TCP:localhost:3121 --verboseVerbose petalinux-boot output (save this as verbose_output.tcl):
