Tool/software:
We are using SDK 10 and want to implement SPL + OSPI + UFS boot. Here's what we've done and the issues we're facing:
1 We've written boot files to norflash
2 We've modified the bootcmd
config BOOTCOMMAND
string "bootcmd value"
depends on USE_BOOTCOMMAND && !USE_DEFAULT_ENV_FILE
default "run ufs_or_mmc_boot" if ARCH_K3
default "bootflow scan -lb" if BOOTSTD_DEFAULTS && CMD_BOOTFLOW_FULL
default "bootflow scan" if BOOTSTD_DEFAULTS && !CMD_BOOTFLOW_FULL
default "run distro_bootcmd" if !BOOTSTD_BOOTCOMMAND && DISTRO_DEFAULTS
help
This is the string of commands that will be used as bootcmd and if
AUTOBOOT is set, automatically run.

Current results:
- All cores can boot
- Linux can boot
- But when executing source ./vision_apps_init.sh, we encounter errors

I'd like to confirm if my approach is correct.
If not, what should I do differently?
