Tf cards cannot be mounted automatically

Products Support DragonBoard410c
#1

Currently, I’m working on a redesign based on db410C hardware.Compared with the standard version of DB410c, the current board does not have CODEC, DSI, etc., and some function values retain WiFi.Now the tf card cannot be mounted automatically after power-on is inserted and some regulator will be printed. After adding some power supply to the drive, it still cannot be detected automatically.Have you ever encountered this kind of situation or given some advice.Below is a partial error log.
thanks.

Could you please add the custom board tag.

Which software release are you running? what is the format/filesystem type of the partition?
At least the SDCARD seems detected:

Are you able to mount the partition manually?

#3

Yes, I can manually mount the tf card.In essence, the current running system is the 17.09 release,The current partition format should be vfat.There is no other difference between the tf part schematic diagram and the standard db410c.thanks!

#4

In the early days of the 410c we did have difficulties reading some SDcards. If I remember correctly, the root cause was the power supply voltage level being either too low or too late (or both?).

Go back to the basics: Use a scope to ensure that there is enough voltage to supply your SDcard, and that the supply is actually turned on before you try to communicate with the SDcard.

I would also check that the supply to the ESD protection diodes is turned on.

#5

Ok so seems the issue is just about auto-mounting the sdcard, AFAIK, this is done via udev and udisk2. check that you have mmc/udisk rules in /lib/udev/rules and check that udisk2 daemon/process is running. I suggest to use udiskctl monitor to monitor activity/events.

#6

I try to use udiskctl monitor to monitor the changes of mmcblk.Hot-swap sd card will indeed generate logs, but now want to insert sd card at any time will be automatically mounted.In addition, I added content in /etc/fstab, but if I did not insert the sd card during startup, the system failed to log in, prompting a partition error.The act of inserting the sd card can be done at any time.
The following is the content of /etc/fstab:
/dev/mmcblk1p1 /media/linaro/SD vfat auto 0 0
The following is the startup status of the unplugged SD card:

Now I have no idea, give some advice, thank you

#7

Please attach the output (e.g. using pastebin).

Yes, don’t use fstab for removable medias.

#8

The following is the log generated by a hot plug process, thanks

This means it should be automatically mounted by udisk, but it’s not, for unknown reason…

This is a very old release, please update.
