PROCESSOR-SDK-AM64X: Issue while running create-sdcard.sh in Processor SDK of AM64x

Amey P

Tool/software:

Hello Team,

I am encountering issue with the create-sdcard.sh script provided in the Processor SDK Linux for AM64X. I have been following the steps outlined on your documentation page:

Processor SDK Linux Create SD Card with Custom Images

I chose Option 1 to create an SD card using the pre-built images from the SDK. However, I am facing a problem where,
instead of creating both the boot and rootfs partitions, only the boot partition is being created. The rootfs partition is not being executed or created as expected.

I am getting error messages as "mount: /home/diana/rootfs: wrong fs type, bad option, bad superblock on /dev/sdb2 ,missing codepage or helper program or other error"

I have verified the following:

    The script runs without any visible errors during execution.
    I am using the latest version of the Processor SDK Linux and have followed the provided documentation carefully.
    I have attempted the process multiple times, including reformatting the SD card between attempts.

Could you please provide guidance on what might be causing this issue and suggest any troubleshooting steps I might take?
Additionally, if there are any known issues or updates related to this script, please let me know.

Thanks

Hi Amey,

did you try multiple SDcards already? Maybe the SDcard has an issue. In such cases I always try with a new card first.

We are talking about RT-Linux SDK 10.0, correct?

Hello Frank

After changing the memory card. the issue was resolved.

FYI: The earlier card was Sandisk Ultra 32GB (which didn't work) and the new one is Sandisk Edge 16GB card

Thanks

Thanks for the update. Then we will close here.

(I have quite a few "bad" SDcards... usually it is cheaper to throw them away than to bother...)

Hello Amey,

This is unrelated to your experience with creating an SD card, but I'll document it here just in case:

For a while, we had trouble getting the AM64x SK EVM to work with some brands of SD cards. The issue was related to EVM design, and is now documented in the users' guide:
https://www.ti.com/lit/spruiy9

5.7 Issue 7 - uSD Boot Not Working
Affected Version: E1, E2, E3, E4, Rev A Severity: High uSD boot does not work with certain brand SD cards. The EVM does not have the pull up resistors populated on the MMC1 interface. This is causing marginal failure with some SD cards.

Solution: Installing 10K resistor on R68, R69, R70, R84, R85 and R466 in the top side of the EVM resolve the issue.

Regards,

Nick
