AM335x EVM-SK: touchscreen is not working

Hi,

Did you try using the create-sdcard.sh script to create a new SD card? Perhaps something went wrong to this one.

The create-sdcard.sh script is located in <sdk_folder>/bin/

Best regards,
Miroslav

Thank you for your reply Miroslav,

I run the create-sdcard.sh and the output on the terminal is

ege@ege:~/ti-sdk-am335x-evm-06.00.00.00/bin$ sudo ./create-sdcard.sh


################################################################################

This script will create a bootable SD card from custom or pre-built binaries.

The script must be run with root permissions and from the bin directory of
the SDK

Example:
 $ sudo ./create-sdcard.sh

Formatting can be skipped if the SD card is already formatted and
partitioned properly.

SD Card is not correctly partitioned

################################################################################

    Select 2 partitions if only need boot and rootfs (most users)
    Select 3 partitions if need SDK & CCS on SD card.  This is usually used
        by device manufacturers with access to partition tarballs.

After this operation, when I insert my microsd card to my starter kit, touchscreen still is not working.

Hi,

Try a new SD card. Judging by the "dd" operation error output, your SD card may have a hardware issue.

Best regards,
Miroslav

P.S. Please, when posting logs to the forum, attach them as a log file, so that the post is clean and easily readable.

I've had formatting errors on micro sd cards before.  You may want to check your SD adapter or make sure the card is inserted properly in your PC's SD slot.  You can also run Ubuntu's disk utility: System->Admin->Disk Utility.  Click on the sd partition and run an error check. 

Sometimes, the sd create script will fail to reformat the card, but with Ubuntu's disk utility, you may be able to delete the partitions and reformat the card.  Then try the create script again.  I have been able to 'restore' some sd cards this way. 

However, an engineer's time is valuable, so you'll have to decide whether it is worth trying to keep restoring a possibly defective card or buying new ones.  I've tried class 4 thru class 10 cards, kingston brand with a noticeable difference in speed with class 10s but no difference in reliabilty, ie, equal 'corruption' rates for each class.

Thank you for your answers.

@Miroslav: I will buy another micro SD card, if I can't solve the problem with the method argeebee suggest. Thank you for your interest.

@argeebee: I opened the disk utility and I choose the mass storage device but unfortunately there is no option with error check.  When I choose my local hard disk, I have the option with check filesystem but for the mass storage device I have no option with this. I am sending the printscreen of my disk utility. When I select format drive, the system faced with error. What should I do to restore the disk? By the way, thank you for your interest.  

Best regards,

Ege

"When I select format drive, the system faced with error."

Even a fresh blank card out of the box should allow a format.  The capacity of your card can be obtained, so its controller may be working.  Check the lock tab on the SD adaptor and make sure it is not locked.  Also, to make sure the adaptor is ok, try another SD card and see if the disk utility can see it.

You can only do an error check on a formatted partition.  I suggested an error check after a format to verify that the format could write the card properly.  If you can't recover the card, a new card is relatively cheap.  Another alternative is to boot via NFS, but that can be difficult on the SK's usb/serial port.
