Hello .

I work with the i.MX6 SoloX SABRE-SDB and I need the M4 to boot much faster. I measure a time about 300 - 400 ms and i read it can be faster (System should be initialized after 11 ms).

The command 'run m4boot' is first at the u-boot environment variable bootcmd.

 

All I tried till now is the following:

in the File include/configs/mx6sxsabresd.h I undefined

CONFIG_VIDEO

CONFIG_VIDEO_GIS

CONFIG_SYS_LONGHELP

all USB configs

CONFIG_CMD_NET

CONFIG_CMD_MEMTEST

CONFIG_DISPLAY_CPUINFO

CONFIG_DISPLAY_BOARDINFO

 

But that didn't affect enought.

Maybe I could silent all output on serial while u-boot, but I tried and it didn't

work for all output.

I hope somebody has some experience with this and can help me.

Thank you.
