AM4376: MMC-utils problems

Gunter Schmer

Part Number: AM4376

Hi,

a customer is using Processor SDK 5 and has pulled in mmc-utils from Yocto and trying to run it. They are seeing that the mmc-utils responses are empty, so somehow it is not working well.

Is there an mmc driver dependency for mmc-utils?

Do we have mmc-utils working inside of our PSDK in a test maybe?

The customer is trying to get some EMMC diagnostic utilities in place.

Additionally they are seeing that the /sys/devices health files are also missing.

Thanks,

Hello Gunter,

In the past, I have helped a couple of customers with mmc-utils and here are the reference threads:
1.https://e2e.ti.com/support/processors/f/791/t/788489?Linux-AM4372-How-to-add-mmc-utils-package
2.https://e2e.ti.com/support/processors/f/791/t/751085?Linux-AM3352-eMMC-5-Health-Reporting-Functionality-using-eMMC-4-3-Software

Please keep in mind that TI did not develop the mmc-utils tool and based on the code, I do not see any dependencies on the mmc driver.
