I have config sdmmc3 in the dts to support sdcard,
and it was worked success.

but when I try to use another sdcard,it was failed.
log is below :
dmesg_sdcard_failed.log (254.8 KB)
please try to format all the cards to ext4 and try again.

thank you for reply!
I 'll try it soon.

I change the format to EXT4, but the same error happened again.
this is the method how I switch the format
sudo umount /dev/sde
sudo mkfs.ext4 /dev/sde
Do you have AGX Xavier devkit that can reproduce this issue?
Xzz

This is a nice direction, I never think it bofore.
I will try it tomorrow, thx u!

my devkit is Jetson Xavier Nx , it doesn’ t have a sdcard slot on carried board but on the SOM.
Do we have another method?
I said Xavier AGX devkit…
Xzz
10
our machine structure is Jetson Xavier Nx SOM + cusomer carried board .
I’m not sure if we can flash Xavier AGX devkit in it.
No, I mean go get one AGX Xavier devkit and see if you can reproduce this on that…
What device tree change did you update for your carrier board?
And do you have schematic to share?

ohhh… I’m sorry for misunderstanding!!
I dont have a AGX Xavier devkit.
this is my change:

Do you have schematic to share?

Hi， WayneWWW，
do u have any suggestion?
Could you share the schematic that has every pin in use here?
Xzz
18
please check it
23-0321 sdcard.rar (253.3 KB)
Could you measure the 3v3 is really enabled by the EN pin when you plug in the sdcard?
Xzz
21
before I plug in the sdcard, 3v3 is always high.
after I unplug the sdcard，3v3 is being pulled low and high in a short time
Xzz
22
so I can make sure that 3v3 is really controlled.
and this is the plug sdcard and success log.
