Hello
Please try using the SD card demo image (it has .sdcard file extension).
i.MX 6 Series Software and Development Tool|NXP
You may apply Win32DiskImager to copy the image to SD card
under Windows host.

Dear Yuri

Dear Yuri
Thank you very much. found problem!! I unintentional setting fuse (boot mode is change), can I read fuse status via command or tool?
Hello,
Good starting point is to read IMX6 RM (fusemap, system boot, and
on-chip OTP Controller) and AN4581 (Secure Boot on i.MX50, i.MX53, and i.MX 6
Series using HABv4)
https://cache.freescale.com/files/32bit/doc/app_note/AN4581.pdf
then you can use command ‘fuse’ of u-boot.
Also, after Linux kernel boot /sys/fsl_opt may be used to review the fuses.
Regards,
Yuri.
Thank you help, this helpful.
