Unable to read sd card

[bmeinka]

I have a kde ce pinephone, and I am having a problem reading the sd card. I have tried with two different cards with the same results.

The sd card is listed in lsblk, however none of the partitions on the card are listed. I thought that was strange, so I tried to open the device in fdisk, but all I got was this error:

Code:

fdisk: cannot open /dev/mmcblk0: Input/output error

It seems to me like this is a hardware issue, but I don't know for sure. Is there something I'm missing here?

Just a question because I have seen users do this before (not saying this is the case here but have to ask anyway). Is the sd card in the correct slot? It is a double slot. Top is for the sd and bottom for the sim.

Other questions assuming the above question does not apply:

Are you trying to boot from the sd? (This is what the sd slot is intended for. It is the first boot device)

Are you trying to mount the sd while booted from the EMMC?

It is in the correct slot. I am trying to boot from it, although trying to mount it while booted doesn't work either.

I have already verified that the sd card is not counterfeit and that the flashed image isn't corrupted.

Hmm. Which Distro are you trying to boot, and what was your method of imaging the card (dd, Gnome-Disks, Etcher)?

I have tried:

• Arch Linux ARM
  
• Jumpdrive
  
• Ubuntu Touch
  
• PostmarketOS edge and stable
  

I started off using dd, but switched to etcher after a few failed attempts to boot in hopes I was flashing the sd cards wrong. Got the same results either way.
