Which SDMMC could be used for boot media on Jetson nano?

[autolabor]

I want to design a Jetson Nano carrier board, and I can not sure that if SDMMC3 can be used for boot media?

Here are some information about boot sequence in design guide:

### Boot Sequence and Sysboot Configuration Files
U-Boot functionality includes a default booting scan sequence. It scans bootable devices in the following order:
•External SD card
•Internal eMMC (Jetson TX2 series devices only)
•USB device (Jetson TX2 series devices only)
•NFS device
U‑Boot looks for an extlinux.conf configuration file in the following directory of the bootable partition on each bootable device:
<rootfs>/boot/extlinux
Upon finding the extlinux.conf file, U-Boot performs the following steps:
1.Uses the sysboot command to read out boot configuration from extlinux.conf
2.Loads the kernel Image file
3.Boots the kernel
The Image file is user-accessible in the <rootfs>/boot location after booting. The extlinux.conf file is user-accessible in the <rootfs>/boot/extlinux location. You can easily change these files to test your own kernel without flashing.
The file extlinux.conf is a standard text-format sysboot configuration file that contains all boot information. It indicates the kernel image filename, the device tree blob filename, and the kernel boot command line.

Is “External SD Card” include SDMMC3?

[WayneWWW]

Yes, if you add an extra sdcard slot on your board, it can be used to boot rootfs.

[autolabor]

ok, by the way, are VDD_EN and CD signals necessary in custom board design?

[WayneWWW]

Yes, they are necessary.

[autolabor]

I have deleted VCC_EN signal and load switch, and CD signal is reseverd.

I could not seen any message in dmesg, and can not seen any device in ls /dev/sd*.

In my opinion, It is should be OK :the 3.3v power that for SD card supply always exist.

Could you tell about the power management information of SD card ?

Hi,

Did you configure the dts file?

Jetson Nano Production Module - SD Card Interface Software Reset Problem

Hi, I have a problem with jetson nano’s Sdmmc interface. About development environment: I use Jetson Nano Production Module(P3448 rev.B01) Baseboard is own production. (We use Emmc for Jetpack Image, Sdmmc Interface for extra storage). JetPack 4.3 with kernel 4.9. I tried different brands and models of sd cards. The problem is when I try to write big chunks of data to sd card(with UI or dd command) the kernel hung and reset the board with the error below. Smaller data writes (less than 120 s…

Hi , WayneWWW

I have configurated DTS files today, but it is look like does not work(could not be used for boot or general mmc).

If SDMMC3 used for boot, the message like these:

I found that when no boot media plugged ,the result is equal(means that SDMMC3 is does not work).

Here are my “dtis” files which build from Nvidia official pinmux configuration tool.

Hi,

This is wrong.

The dts files need to be downloaded from our download center and follow the L4T developer guide to build it as a dtb.

Then, flash this dtb to your board to make it work.
The pinmux dts is not what I am talking about here. They are two different things.
