Hi @ok 

Would you share result of these command on the console to investigate the route cause ?

ls -lA /usr/bin/

df -kT

Best regards,

Hi @watari

Hi @ok 

According you shared log file (it's not my request...), the partition /dev/mmcblk0p1 is broken.

>[ 13.424684] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Starting udev

So, would you run fsck for /dev/mmcblk0p1 ?

Best regards,

[ok]

HI @watari 

I'm new to this, what is fsck and how i can run this?

[watari]

Hi @ok 

Refer the following step, if you can mount SD card on linux host.

1. unmount SD card on linux host (ex. umount <device name> (ex. umount /dev/mmcblk0p1)

2. run fsck command on linux host (ex. fsck /dev/mmcblk0p1 or fsck.vfat /dev/mmcblk0p1)

Refer the following step, if you can only prepare Windows host.

1. run cmd.exe as administrator privileges

2. chkdsk <drive name> on cmd.exe console (ex. chkdsk d:)

Would you try it ?

Best regards,

[ok]

Thanks @watari  i will try it with my windows machine and update you.

Hi @ok 

OK.

Would you share result of these command on the console to investigate the route cause ?

ls -lA /usr/bin/

df -kT

These information is important to investigate the route cause.

Hi @ok 

Would you try dosfsck on proper linux os ?

# example

sudo mount <your device>

## verify and repair your partition

sudo fosfsck -t -a -w <your device>

# How to install dosfsck on ex. Ubuntu

sudo apt install dosfstools

Best regards,

Hi @ok 

Can you prepare VM, ex build VM by Virtual Box ?

Best regards,

[ok]

Hi @watari 

Understand , i can do but .. before that the question in my mind is.

I have installed tools size of around 28GB in my windows , Still i need linux machine to run sample example means its really bad for Xilinx. Xilinx boards are then not comfortable with windows. Its kind of failure design. Im frustrated with this board. I lost the hope.

Thanks

Hi @ok 

Here is my opinion to resolve quickly this issue.

First of all, I suspect broken VFAT table or data on SD card.

# How to fix it.

I already mentioned before, the best way is using linux to repair SD card, if you follow my suggestion.

Because I don't have enough knowledge about it on Windows.

I recommend the followings, if you hardly prepared linux environment as VM guest OS on Windows.

## Prepare linux gadget

I'm sure that "Raspbery pi" which is most famous cheaper gadget for linux is best solution to repair SD card.

You can install raspbian OS which is one of Debian (similer Ubuntu) on it.

Would you consider and try them ?

P.S.

BTW, perhaps the easy way to resolve it is you might change SD card to new one.

Hope it your helps.

Best regards,

[ok]

hi @watari 

Thank you! Let me change the SD card 1st and update you. Unfortunately raspberry pi not having here.

I had 4 Ras Pi , 3 Laptops (including Linux one), 4 Tablets everything in different place. I'm at my native, that's the reason i'm struck.. with current laptop and limitation
