Verdin Am62 MMC2 Configuration Not working

Technical Support
,
1

Hi all,

We are trying to connect an SD card to the MMC2 Port on our system, we have enabled the sdhci2 on your device tree, but it seems it is not working , i mean when card is connected we are not able to detect in the linux. we are able to see mmc2 driver is loaded in the kernal boot logs, but whenever we connect the SD card, it is not detected.

below are the Device tree added in our system:

by default 3.3v is provided to the SD card. we are able to see 1.8V on the SD_CD when the card is not connected and when connected it goes LOW.

	sdhci2: mmc@fa20000 {

Hi, I’m the Toradex AI Assistant. The Toradex Support team will follow up with you shortly!

Did you like my answer?

:+1: :-1:

It looks like you’ve done a good job setting up the device tree for the MMC2 port on your Verdin AM62 module. However, there are a few things you might want to check and try to resolve the issue:

  1. Check the Pin Configuration:
    Ensure that the pin configuration in the device tree matches the actual hardware connections. Double-check the pin numbers and their configurations.

  2. Voltage Levels:
    You mentioned that 3.3V is provided to the SD card and you see 1.8V on the SD_CD pin when the card is not detected, which goes LOW when connected. This seems correct, but ensure that the voltage levels are stable and within the expected range.

  3. Driver and Kernel Logs:
    Since the MMC2 driver is loaded, check the kernel logs (dmesg) for any error messages related to the MMC2 interface or SD card detection. This might give you more insight into what is going wrong.

  4. Device Tree Status:
    Ensure that the status property for sdhci2 is set to "okay" and not "disabled". From your provided device tree snippet, it looks correct, but double-check for any typos or inconsistencies.

  5. GPIO Configuration:
    Verify that the GPIO used for card detection (cd-gpios = <&main_gpio0 71 GPIO_ACTIVE_LOW>;) is correctly configured and functioning. You can test this GPIO separately to ensure it is working as expected.

  6. Clock Configuration:
    Ensure that the clocks are correctly configured and enabled. The clock-names and clocks properties should match the hardware specifications.

  7. Additional Properties:
    Sometimes additional properties might be required for proper operation. Refer to the TI AM62 documentation and the Toradex device tree reference for any additional properties that might be needed.

  8. Testing with Another SD Card:
    Try using a different SD card to rule out any issues with the card itself.

  9. Kernel Configuration:
    Ensure that the kernel is configured to support the MMC/SDHCI interface. Check the kernel configuration (.config) for the relevant options.

If after these checks the issue persists, you might want to reach out to Toradex support with detailed logs and your device tree configuration for further assistance.

Any update on this issue?

Hi @naveenkumar.muthusam ,
Is it a custom board that you are using along with Verdin Am62?

5

Hi @sahil.tx ,

yes it is a custom board developed which is using the Verdin am62 SOM

Below are the schematics of the SD card MMC2 connector

is there anything missing in Device tree configuration shared above?

please let me know.

we are still facing issue in mmc2, SDCARD is not detetced on this port, but we have verfied that the SD CARD is working on the EVM in MMC1.

Hi @naveenkumar.muthusam ,

Thanks for sharing schematic and modification but with provided information it is not clear where and which file you have made modification. So kindly share git diff so as we can see all changes.

Additionally please also share below information to help us understand your setup

  • BSP/OS version
  • dtb you are using.
  • dmesg logs

Finally please note we have not tested MMC2 as same is not populated on our development board. That said if you check device tree for k3-am62-verdin-nonwifi.dtsi « ti « dts « boot « arm64 « arch - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules sdhci2 is already defined and is disabled. I suggest you to enable and test.
May be based on your requirement you need to tweak pad settings but that’s for another test.

Best Regards
Ritesh Kumar

Hi @ritesh.tx,
we have made changes in the k3-am62-verdin.dtsi. As MMC2 pin configurations were already provided in this file CMD,CLK,D0-D3, we have added only the CD for the MMC2.

The file k3-am62-verdin-nonwifi.dtsi file is completely commented and we are not including this file in the k3-am62-verdin-nonwifi-dev.dts.

we are able to use the UART5 but MMC2 we are facing issues in detection.

Hi @ritesh.tx ,
any updates in this issue?

Hi @naveenkumar.muthusam,

Thanks for sharing logs, upon checking we found that some activity is being done for mmc2 and driver is being loaded.
Can you also test add “ti,fails-without-test-cd” to sdhci2 node and see with this you are able to detect card.

Now please note that we don’t have custom hardware with us to test and for some reason you didn’t share complete changes. It is difficult to suggest anything remotely that why sd card is not detected.

I will suggest to please try with default device tree and bsp with simply enabling sdhci2 and see if this work.
You can also try to probe MMC and CD signals to further check for any activity.
Also please share complete schematic to verify pins and git diff output to understand all changes.

Best Regards
Ritesh Kumar
