Part Number: AM625
Hi TI community,
Thank you for all of your support. I am using AM625 on our board and I have a question regarding the mmc1(sdhci1).
I want to mount eMMC on mmc1(sdhci1).
Here is the situation I have met,
1. I'm able to successfully read from the SD card during u-boot and rootfs , but eMMC is not able to detect.
2. When I short the SDCD pin to GND(pull low) , eMMC can be detected and read in rootfs.
3. Then I tried to modified the setting in the device tree of kernel & uboot, I failed. The eMMC can not be detect.
The modification is as follows,
1. add "on-removable;"
2. add "no-1-8-v;"
A lot of SDHCI register dumps logs getting printed continuously,

3.After that, I tried to remove "non-removable;" and add "gpios = <&main_gpio1 48 GPIO_ACTIVE_LOW>;" and the pin D17 set to the mode 7 as follow:
main_mmc1_pins_default: main-mmc1-pins-default {
pinctrl-single,pins = <
AM62X_IOPAD(0x23c, PIN_INPUT, 0) /* (A21) MMC1_CMD */
AM62X_IOPAD(0x234, PIN_INPUT, 0) /* (B22) MMC1_CLK */
AM62X_IOPAD(0x230, PIN_INPUT, 0) /* (A22) MMC1_DAT0 */
AM62X_IOPAD(0x22c, PIN_INPUT, 0) /* (B21) MMC1_DAT1 */
AM62X_IOPAD(0x228, PIN_INPUT, 0) /* (C21) MMC1_DAT2 */
AM62X_IOPAD(0x224, PIN_INPUT, 0) /* (D22) MMC1_DAT3 */
AM62X_IOPAD(0x240, PIN_INPUT, 7) /* (D17) MMC1_SDCD */

};But now SD card is not able to get in uboot as follow,

I feel confused . Why is it not detecting the eMMC but SD card can do that?
It seems to be related to SDCD pin detect problem.
How can I detect eMMC during uboot and rootfs with correct setting?
Here's the relevant dts file.
