Subject: [PATCH v2 0/1] arm64: tegra: enable SDIO on Jetson Nano M.2 Key E
Date: Mon, 2 Dec 2019 22:51:59 +0100 [thread overview]
Message-ID: <20191202215200.9656-1-tszucs@protonmail.ch> (raw)
It turns out SDMMC3 on the Jetson Nano module is wired to respective pins of
the carrier's M.2 Key E socket. However, it is not enabled. I see no reason
why. This block is functional and has a fixed 1.8 V I/O supply. Perfect for
SDIO cards nowdays. I think it would make sense to enable this feature. PCIe
could be used for something else.
Kind regards,
Tamas
