| - | default_bootcmd=run uenvboot; run cp_kernel2ram && bootm ${netstart} | ||
| - | </code> is created by PetaLinux as <code> | ||
| - | default_bootcmd=run uenvboot; run cp_kernel2ram && run cp_dtb2ram && booti ${netstart} - ${dtbnetstart} | ||
| - | </code> with the typo in ''booti'' instead of ''bootm'' command.\\ \\ To fix this bug, edit the ''platform-top.h'' file (it would not be overwrite if you reconfigure the boot or kernel): <code> | ||
| - | vim ./project-spec/meta-user/recipes-bsp/u-boot/files/platform-top.h | ||
| - | </code> and add the following entry at the end: <code> | ||
| - | /* Due to a bug where having u-boot load dtb from SD card causes the boot | ||
| - | * command to default to using booti instead of bootm on Zynq, the defult build | ||
| - | * fails to boot. This boot command override is a temporary workaround. | ||
