Hi,
In below, debian flasher emmc image u-boot.img and MLO output. I want to minimize (now it boots at 2.621 seconds). Currently I suppose that 1sc bootdelay when u-boot is opening, how can I close it?

There are some errors and warnings on u-boot as you seen,
1) 0.066 0.066: spl_load_image_fat_os: error reading image args, err - -1
2) ** Unable to read "uboot.env" from mmc0:1 **
3) ** Unable to read file boot.scr **
4) Error: "mmcargs" not defined
how can I fix them?
Is there any way to optimize u-boot? (I also read sitara boot time reduction wiki but it doenst help me)
Best Regards,
Umit
