Are you using the NXP i.MX6 SoloX SDB board?

[Rita_Wang]

How is your download process? You can use the uuu tool to download the images to the SD card on your board.

I followed the IMX Linux Users Guide exactly,I have no problem with commands and operations in Ubuntu.

The question that has been bothering me for a long time is, which files should I burn to my development board?(IMX6 SX-SABRE SDB ),Because I want to boot from my SD card,So when I burn files into the development board, I always look for those with SD suffix, But I failed.

for example, However, after I complete all the operation steps (U-boot, Zimage, DTB, rootfs), I will have the following error:Either the development board is resetting the CPU all the time, or it's stuck in the Starting Kernel.

u-boot:

1. u-boot-imx6solosabresd_sd.imx
2. u-boot-imx6sxsabreauto_sd.imx
3. u-boot-imx6sxsabresd_emmc.imx
4. u-boot-imx6sxsabresd_sd.imx

BUT ,when I flash imx-image-full-imx6qpdlsolox.wic to my board,the development board will load normally to the login page,I just need to type root to get root privileges, without having to type a password

[Rita_Wang]

For the u-boot please use this one u-boot-imx6sxsabresd_sd.imx this is for your board sd card.

You also can use the imx-image-full-imx6qpdlsolox.wic which including all.

I used mfgtool to burn the relevant files to the development board, which was also successful.

I was able to successfully enter the login screen.As the following:

Starting atd: OK
exportfs: can't open /etc/exports for reading
NFS daemon support not enabled in kernel
Starting system log daemon...0
Starting kernel log daemon...0
* Starting Avahi mDNS/DNS-SD Daemon: avahi-daemon [ ok ]
Starting Telephony daemon
Starting Linux NFC daemon
Starting crond: OK
Starting autohdmi:
Running local boot scripts (/etc/rc.local).

Freescale i.MX Release Distro 4.1.15-2.0.0 imx6qdlsolo /dev/ttymxc0

imx6qdlsolo login: root
root@imx6qdlsolo:~# ls
root@imx6qdlsolo:~#

When I used Ubuntu to burn separately, I failed.

[guojqf]

I know that。I also tried to burn the.wic file to the development board and this also made it to the login page。

for zImage 、dtb and rootfs,Which file should I choose?
