Jetson Nano Production Module - SD Card Interface Software Reset Problem

Hi,

You need to add this to the sdhci controller dts and you have to specify the GPIO according to your schematics.

Hi,
In our schematic label SDMMC_CD is connected to GPIO_PZ2(GPIO08 pin208). It is tachometer GPIO, I guess. Because of that I asked it on the previous post. My plan is: Commend tach_gpio = <0x56 0xca 0x1>; in pfsd node then i will add cd-gpios = <0x56 0xca 0x1>; to sdmmc3: sdhci@700b0400. But i am not sure is the “0x56 0xca” and GPIO08 same.

Hi,
Yes, that phandle is probably the GPIO_PZ2. Actually, I don’t know the answer either.
This is not how we modify dts. Please download the dts source and check how other files include a GPIO instead of directly using the hex of a phandle.

cd-gpios = <&gpio TEGRA_GPIO(Z, 2) 0>;
