Hello,

 

I am trying to staert the card with empty micro sdcard. The system is into eMMc. But when the micro sd card is in the Orange Pi and branch it it not start it failed with message error no system.

 

Why ? 

 

I can't start the Orange Pi with a blank sdcard ?

 

Thanks

If you plugged microsd in board is trying load system from it and when system is not present it stopped.

If you want use free space on you microsd you need to creta ext4 filesystem on it. Copy boot folder from your emmc, change root= folder in boot.scr in boot folder and compile new boot.cmd (I hope there is same filename convention) with command at the end of first file. And than you need write uboot to microsd.

But I'm nove can you explain more that ? Compile boot cmd ? when ?

 

Because When I format sdcart into ext4 and insert to orange pi after boot into emmc it not detect it ....

 

Thanks

The command is mentioned as a comment at the end of boot.cmd :

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

Hello,

 

But is normal that when I insert miscrosd card after launch system it not detect it ?

It is a bit annoying but on the other hand can you insert/remove microsd cards once the card is enclosed in a case ?

Yes, it's normal for sdc_detmode = 3 for mmc0 in fex file.
