Hello, I successfully started the Linux system using arty100t branch and the SD card configuration tutorial in VCU118. But the file system of partition 2 cannot be identified in the system. I searched the media and mnt directories and found none.

In addition, I also tried to format partition 2 as Linux (8300 code is used in gdisk), and the system cannot recognize it also.

Hi,

You need to mount the SD card to see its contents everytime you boot the FPGA prototype. You can use the `mount` command (something like `mount <name of the device> <folder to mount to>`). The name of the device should be `mmcblk0` I think (you might also be able to look it up using `fdisk -l`). Once you are done with the SD card contents you should unmount it (`umount <folder used to mount>`) otherwise it might get corrupted. Hope that helps.

I successfully mounted the SD card, but mmcblk0p2 was used because the second partition needs to be mounted. Thank you.

Hello, I found two problems:
First, when writing data to partition 2 of the SD card, I can use the command copy to write data after using the mkfs.hfs command to format each time. However, if I do not use the mkfs.hfs format, when using the copy write command, partition 2 will be displayed as read-only and not writable
Second, after formatting partition 2 and writing the file test, sometimes the file test disappears after I mount partition 2.

Hello!

Can you please share the command you used? I am unable to get "PrototypeData" to mount on the fpga running linux.

TIA!

This is my error. I am also unable to view the mounted partition on /mnt
