Error with SD Card Image on i.MX6QP

[muhammedk97]

Hi All,

I am new with the NXP and i.MX boards.

I have a MCIMX6Q-SDB board and I am trying to learn according to L5.10.52_2.1.0_LINUX_DOCS.

I bought an another SD Card, and trying to load SD Card Image to it. What I am doing is listed below, step by step:

1. I extracted the "imx-image-full-imx6qpdlsolox.wic" file from LF_v5.10.52-2.1.0_images_IMX6QPDLSOLOX.zip
2. I use terminal to load the .wic file to the sd card with the command that sudo dd if=imx-image-full-imx6qpdlsolox.wic of=/dev/mmcblk0 bs=1M && sync (mmcblk0 is the sdcard)
   
3. After I receive the message "4832+1 records in 4832+1 records out 5066931200 bytes (5,1 GB, 4,7 GiB) copied, 350,891 s, 14,4 MB/s" from terminal, I insert the SDCard to the board and make the SW6 switch: 01000010 according to section that Booting from an SD card in slot SD3 on i.MX 6 SABRE-SD from L5.10.52_2.1.0_LINUX_DOCS.
4. When I power on the board I receive the errors below:

According to the document SDCard image (.wic file) supposed to have U-Boot, the Linux image and device trees, and the rootfs. But the rror says "can't get kernel image"

If you have any idea about what I am doing wrong. Please help me.

I solved the problem with this:

I believe you need the uboot environment in the board. I am not sure how can I send the command. I don't receive any terminal in board and I cannot send any command via serial cable.

Please, advise.

I tested on my board by uuu tools successfully, maybe you can try it, my command
uuu.exe -b sd_all u-boot-imx6qpsabresd_sd.imx imx-image-multimedia-imx6qpdlsolox.wic

Dear Joanxie,

Thank you for your replay.

I plugged my sdcard to my pc and tried your command but it says "Wait for Known USB Device Appear...".

Can you tell me what should I do? How should I do run the command? Should I select the SDCard somehow? I guess what I am doing is a ridiculous mistake but I am in a very early stage. If you can help, I would be really appreciated.

Regards,

[joanxie]

no, don't insert the sdcard to the PC, to the board instead, then download the images to the board directly

[joanxie]

pls give me the uboot environment with command "printenv"
