SD High-Speed Card Not Working on Custom Motherboard error -84 -110

I have a custom motherboard, and the SD high-speed card does not work. However, it works fine in low-speed mode, i.e., when modifying max-clk-limit = <0xc28cb00>; ddr-clk-limit = <0xc28cb00>; to below 50MHz（According to the guidance of AI）, it remains stable. Otherwise, I get error -84 and -100. I hope someone can help me, thank you. Below is the device tree configuration.

I don’t know what you want to point out in that picture. There is nothing useful from your schematic.

You basically shared nothing. No one knows where do those lines go to. Nothing there shown how the connector side is wired.

Which Jetpack release are you using?

Are you sure your device tree is matching to the board design?

4

I’m sorry, I modified the content and uploaded the picture again. I’m using the official device tree, and I just added cd-gpios = <0x85 524 0x1>; in sdhci@700b0400 . Then I removed cdgpio from sdhci@700b0000 , otherwise the SD card cannot be detected.

5

So what is “cd-gpios = <0x85 524 0x1>”? Which pin is that ?

And if you have cd-gpio there, you should not remove it. Your issue is from something else so you should not remove it.

"Hi WayneWWW,

Please excuse me, but all of this information was provided by AI. I don’t have personal expertise in these matters. The AI also suggested removing cd-gpios, and indeed, doing so resolved my initial issue. Adding cd-gpios to sdhci@700b0400 also resolved the hot-plugging issue, and now, with the AI’s assistance, I’m able to use high-speed SD cards (though I haven’t ruled out the possibility that the issue was specific to that particular SD card). The speed now reaches over 90MB/s.

Currently, the only remaining issue is that during a soft reboot, the SD card operates at 50MHz. It only operates at 200MHz after a cold reboot or hot-plugging. Here are some logs:"
