An internal slot does not necessarily mean the card is non-removable. I don't think its location alone justifies keeping card detect asserted: GPIO88 would report a card present even when the slot is empty. > We check the vmmc-supply is p3v3.

Could you confirm from the schematics that the SD power wiring matches CoM260 and that the card's VDD is actually connected to ALDO4? If so, this supply reference is fine. The same SDK configuration alone does not establish the wiring. If the card instead uses a fixed, always-on supply with no software power control, vmmc-supply is optional for the MMC core; it should not point to an unrelated ALDO4 rail. --=20 Troy Mitchell --1d5c24782d6347cbf5fcdf0c6fbf3eaef92642292ff9818598bdb521dc6b Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iIMEABYKACsWIQSL4Ay2cExaPXAQcU2YCe+A+TM0LwUCarN5dA0caUB0cm95LXku b3JnAAoJEJgJ74D5MzQv0SkBAJoTYlHEntw6qzTvJySy6HApBMRe5LlDuAd7JRLO XP9NAP0XoDVs3rpymXWxOxY0Su4MGjNUGi1VGG4nipsub909DA== =Ux3W -----END PGP SIGNATURE----- --1d5c24782d6347cbf5fcdf0c6fbf3eaef92642292ff9818598bdb521dc6b-- --===============4258157916033218566== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv --===============4258157916033218566==--
