Hi, I am using Xilinx AVNET 2020.2 BSP to create a petalinux project. Link to BSP : https://avtinc.sharepoint.com/teams/ET-Downloads/Shared%20Documents/Forms/AllItems.aspx?id=%2Fteams%2FET%2DDownloads%2FShared%20Documents%2Fprojects%2Fpublic%5Frelease%2F2020%2E2%2FBSP&viewid=dba68156%2Dce4b%2D4ebb%2Db7a7%2Dec03b27b013d
When i create the project, the BSP provides me with a pre-built-/linux/images/* folder which contains all the boot images which can be used to boot using SD card. I am trying to replicate the pre-built/linux/images/BOOT.BIN by using the following command :
petalinux-package --boot --fsbl ./pre-built/linux/images/zynqmp_fsbl.elf --atf pre-built/linux/images/bl31.elf --kernel pre-built/linux/images/image.ub --pmufw ./pre-built/linux/images/pmufw.elf --psmfw no --u-boot ./pre-built/linux/images/u-boot.elf --dtb ./pre-built/linux/images/system.dtb --force
The above command ideally should create an identical BOOT.BIN in the images/linux/ area since i am using the pre-built *.elf files (boot loader files) to package. But when i try to boot using the generated BOOT.BIN the FPGA hangs at the kernel boot stage. Whereas the already existing BOOT.BIN in the pre-built/linux/images area does not cause this hang issue and boots successfully, I am not able to understand where I am going wrong.
I am trying this debug step, inorder to debug another similar boot hang issue which is related to boot from SD card where in i modify the device tree to enable GEM0 ethernet MAC , do a petalinux-build and then finally package the generated boot images into a BOOT.BIN. To clean up the flow i was trying the above but I am stuck here. Kindly help.
