AM62A7-Q1: SD card boot issue in customized board

Hi Tejas Patel,

1. The first I2C error is because SPL is still expecting the SD_EN connected to the I2C expander. This should be corrected in SPL.

2. Data lines at 3.3 V means you will not be able to support UHS cards in hardware. SPL is expecting to switch to 1.8V IOs to proceed with the UHS card but hardware doesn't allow that. Might be possible to direct SPL to work only with old cards but I'm not sure.

Regards,

Stan

Hello Stanislav Stilyanov ,

1: I was able to remove the I2c error by removing the "exp1: gpio@22" node in "&main_i2c1" inside "k3-am62a7-sk.dts"file, 
2: I tried to change the "vdd_mmc1" node by adding this followinf patch"     vdd_mmc1: regulator-3 {
        /* TPS22918DBVR */
        compatible = "regulator-fixed";
        regulator-name = "vdd_mmc1";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-boot-on;
        enable-active-high;
        gpio = <&main_gpio0 42 GPIO_ACTIVE_HIGH>;
        pinctrl-0 = <&gpio42_pins_default>;
        pinctrl-names = "default";  
    };"
Note: here i changed the exp1 with main_gpio0 42 according to our schematic change, but we have noticed that the N22 pin"VSEL_SD_SOC" does not go low resulting in 3v3 supply and not able to switch to 1v8. Maybe because of this reason my SPL throws error.
Can you please help us with relevant solutions(or dts changes) for the same

Hello Tejas Patel,

Thanks for the updates.

We are working onto this. Please expect our feedback today or tomorrow EOB.

Thanks for your patience !

Kind Regards,

Anastas Yordanov

Hello Tejas Patel,

You may want to read through the SD Card interface related checkpoints in this FAQ: Board bring-up FAQ

Please let us know if you found something.

Expect our follow-up early next week.

I appreciate your patience !

Kind Regards

Anastas Yordanov

Hello Tejas,

Can you please share part of the schematics related SD Card? It's a bit difficult to imagine the whole pictute without it.

Thanks,

Stan

SD Card: Pull up is not mounted for CLK pin. 

Hi Tejas,

Are you seeing power applied to VDD on the SD card cage?

Also, I saw an improvement that you may want to do. You can remove the pullup on the CLK since you have already pulldown on it.

Thanks,

Stan

Yes we can see 3v3 on VDD, and pullup on CLK is already removed.

This property is for the SD card power suppy. The "vqmmc-supply" controls the I/O supply. So, you would need to modify this as well according to your schematics to support the 1.8V UHS modes.

Hello Tejas, 

Here are possible steps

Step 1 

Can you please share the PDF version of the schematics to be able to search.

The MMC1_CLK pulldown is expected to be 10K

The ferrite use on the SD card pullups need to be changed to a 0R.

Step 2

Would you be able to fix the SD card interface to 3.3V to check if the SD card interface works and the issue is the GPIO.

Sreenivasa

Hello Tejas, 

Checking if you were able to make progress.

Regards,

Sreenivasa

Hello Kallikuppa Sreenivasa , unfortunately we cant share the whole schematic pdf with you because of our policy, adding to this we tried the changes that  you have suggested but we cant see any difference, i think the problem is that we have removed the IO expander that was used to send reset signal to sd card interface, we can see the voltage is constant 3v3 but i think it should switch to 1v8 to support uhs.

Hello Tajas, 

Thank you for the note, appreciated.

Kallikuppa Sreenivasa said:

Step 2

Would you be able to fix the SD card interface to 3.3V to check if the SD card interface works and the issue is the GPIO.

The below step is to test the SD card interface in legacy default speed without switching 3.3to 1.8V.

In case you have not made these changes and need support, Prashant can guide.

Regards,

Sreenivasa

Yes we have tested with constant 3.3 at our end but we are still getting same error, Prashant Shivhare  do you have any reference dts with related to "vqmmc-supply" as you have mentioned earlier, we have already did the following changes in "vddshv_sdio" node

 

	vddshv_sdio: regulator-5 {
		compatible = "regulator-gpio";
		regulator-name = "vddshv_sdio";
		pinctrl-names = "default";
		pinctrl-0 = <&vddshv_sdio_pins_default>;
		regulator-min-microvolt = <1800000>;
		regulator-max-microvolt = <3300000>;
		regulator-boot-on;
		vin-supply = <&ldo1>;
		gpios = <&main_gpio0 31 GPIO_ACTIVE_HIGH>;
		states = <1800000 0x0>,
			 <3300000 0x1>;
	};

Hello,

Could you please confirm if you are able to boot successfully in 3.3V? If yes, please share the logs. If not, please limit the SD card to SD HS mode as described in the following workaround: https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/11_01_07_05/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory-K3.html#steps-for-working-around-sd-card-issues-in-u-boot

Thanks!

I am able to boot from sd card after adding this line in uboot dts file
"sdhci-caps-mask = <0x00000007 0x00000000>;"

but now i am getting probe error because of kernel dts, i have did the same changes in it too, it runs perfectly when i copy default dtb in it
