Hello Team,
Actually I am trying to use sdk example for sd_card_polling and porting to SDHC2.
But not able to detect and communicate with sd card.
I am attaching pin configuration details and code changes details. So, you can identified what i made changes.
Could you please suggest if i missed anything to use USDHC2 as sd mode with attached configurations.
Its working properly if i use all pins as GPIO and operating as spi mode.
Thanks in advance,
Kishan Patel

Hello Team,
Its working now, the issue was pull-down register connected to the data3 line.
We removed that register and able to access sd-card via sd-mode interface.
Thanks & Regards,

Hi @KishanJPatel,
I do not see any attached files. Could you make sure to attach them on a reply? Also, take a look into this other community post. It also talks about the configuration for using uSDHC2 : https://community.nxp.com/t5/i-MX-RT/Problem-to-use-USDHC2-with-fatfs-sdcard-exemple/m-p/1004795

Hi Edwin,
Thank for the suggestion, I seen that conversation and they are trying to default(different) pin configurations for uSHHC2 compared to pins which I am trying to use.
I am attaching the pin detailsuSHHC2 pinout and updated code(changes in code)uSDHC2 interface to MIMXRT1062DVL6A .
Please let me know if I missed anything or is it possible to access microSdCard using those pins.
Thanks,

Hi @KishanJPatel,
Could you please attach the files directly on one of your replies on this post? I am not able to access Google Drive files. Or if you do not wish to attach these files on a public manner, you can also open a ticket to get support via email, and therefore maintain these files confidential.
BR,

Hi @EdwinHz
Sure, I am attaching file here.
I hope now you can get my concern to access the sd card via usdhc2.
Let me know if you still required any inputs from me.
Thanks,
