Hi,
I downloaded the Qt Demo Image from here and install it on eMMC and after Linux boot up I can’t access SD Card! It is not detected after inserting and removing!
What should I do?
What exact hardware and software versions of things are you talking about? A complete serial console boot log as a textual file may be helpful in analyzing what’s going on.
Thanks for the bootlog. How did you format the card?
Could you stop in uboot and provide the output after the following commands:
#mmc dev 1
#mmc info
Thanks for prompt reply,
I formatted it on Windows 10 with FAT32.
This SD Card is detecting on lxd-demos but on qt-demo It is not detecting.
The output:
Apalis iMX6 # mmc dev 0
switch to partitions #0, OK
mmc0(part 0) is current device

Where is this card inserted?
This SD Card is detecting on lxd-demos but on qt-demo It is not detecting.
It looks like it is detected in U-Boot?

I mean that the SD Card is OK and It is detected and I can use it when I use lxd-demo image instead qt-demo image on my board.
The problem is qt-demo image that don’t detect SD Card after boot up.
when run ls cmd I have only the following in my dev and none of then is my SD Card!
root@b2qt-apalis-imx6:~# ls /dev/ -l |grep "mmc*"
brw-rw---- 1 root disk 179, 0 Jan 1 00:00 mmcblk0
brw-rw---- 1 root disk 179, 8 Jan 1 00:00 mmcblk0boot0

brw-rw---- 1 root disk 179, 2 Jan 1 00:00 mmcblk0p2

U-Boot?
yes it is detected in U-Boot.
How can set it to detect after boot up too.
Thanks
Hi
You are using an Ixora V1.0 with the device tree for an Ixora V1.1. This explains the issues your are seeing.
For your HW version use the imx6q-apalis-ixora.dtb file for the fdt_file U-Boot environment variable.
