Enabling SDIO on 32.6.1 on Nvidia Nano B01 Board

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

I am using Nvidia Nano B01 Board. I am trying to connect Murata uSD-M2 Adapter to connect Nvidia Nano SD card port on uSD interface and wifi module connected to M.2 on Murata Board.

I am using 32.6.1 LFT

Following are the dts changes in b00 dts and iin porg-p3448-common.dtsi in the below node.

  1. Here the issue i am seeing is that the mmc1 clock is 0 and also power is zero.
    Do we need to any specific device tree parameters in b00 dts or common dts for it to work?
  2. Has SDIO worked on 32.6.1 on Jetson Nano B01 board before. If yes please share the working b00 dts where sdio has been brought up?

Sorry that I think I need to clarify one point here before helping you out.

I am using Nvidia Nano B01 Board. I am trying to connect Murata uSD-M2 Adapter to connect Nvidia Nano SD card port on uSD interface and wifi module connected to M.2 on Murata Board.

What is the exact thing you are trying to say here? What is Murata board? A custom carrier board for jetson nano? While it sounds like you are still using devkit board but not custom board?

Do you know what hardware pin you are using here?

5

Murata board is a uSD to M.2 Adapter.

I intend to connect 54591 cypress wifi module to murata board’s M.2 Interface and uSD slot of murata board will get into the SD card slot of Nvidia Nano 01 board.
I am using Murata uSD to M.2 Adpater revision A
https://community.murata.com/s/question/0D55F00009gs9WQSAY/murata-1zm-question-on-usdm2-adapter-rev-b2-rev-a

The intention is to load 54591 cypress module using SDIO on a Nvidia Nano B01 development kit as host.
Please let me know if i was clear.

Yes i am using a Nvidia Nano B01 development kit board bearing board version 180-13449-DAAF-B01
Does SDIO/ SDMMC3 work on Nvidia Nano B01 development kit?

6

Hi,

What is the interface that jetson nano devkit provides here for this Murata card?

I mean which slot does this Murata connect to on devkit? To the M.2 slot? The SDIO function on jetson nano’s m.2 slot is not enabled.

7

Hi,
One end of the Muratha board is plugged into the sdcard slot on the B01 board and on the Murata Board there is a M.2 Slot where i connect the 54591 wifi board.

Hi,

The sdcard slot on the module is for the booting sdcard to use…not for your usecase…

How did you boot up the device if you already occupied the sdcard slot…

9

I have created a USB bootable filesystem disk from which i am booting.

10

This usecase is still not acceptable… The sdcard slot on the module is not sdmmc3…

sdhci@700b0400 is for the sdmmc3 pin which are these pins mentioned here. We don’t support to customize or change the configuration on the sdcard slot of the original module.

11

To support this use case do i need to use any other Nvidia board?

12

Hi,

You may need to get some jetson nano custom carrier board from other vendor.

Our devkit does not have sdcard slot which uses sdmmc3. Only some of our partners/vendors’ carrier boards have.

13

Could you please help me with from where i can buy the custom carrier board i need to use for SDMMC3

14

As part of this table it says “SDMMC3_” signal right. So in this case Jetson Nano B01 Board does it not support SDMMC3?

15

Need to clarify this first.

The “Jetson Nano B01 board” has two parts:

  1. The module which has a sdcard slot on it
  2. The base board, or we call it carrier board. If you are using the one from NVIDIA, then it is called the NV devkit. If this is from other vendors, then it could be their custom board.

What I am talking about here is, the NV devkit does not have a sdcard slot that is based on SDMMC3.
But the module has pinout. So some vendors would connect those pins to their own carrier board. In such situation, we only sell module to them.

16

Hi
I want to just clarify that i am speaking about Murata board on which 54591 is mounted is connected to J501 Micro SD Slot.
Is SDMMC3 supported on J501?

17

No… if you are using NV devkit., then I can tell you that slot is not sdmmc3 without checking the photo…

“SDMMC3” is not some kind of “software feature”. This is the hardware pin.

Jetson SoC has sdmmc1 ~sdmmc4 pins and only sdmmc3 has pin out to the module.

The sdcard slot on jetson nano module is the sdmmc4. But we don’t support to change the configuration on that slot…

18

Thanks Wayne,
Could you please suggest us a custom Nvidia nano board where sd card slot supports SDMMC which would fit our requirement

19

Is sdhci@700b0400 supported on J501?

20

Hi,

sdhci@700b0400 is equal to sdmmc3… So my previous comment already answered your question…

sdhci@700b0400 is the software register address, and sdmmc3 is the hardware pin…

21

Thanks Wayne.
Request you to refer a few vendors from whom i could buy custom Nvidia Nano boards suiting my requirement.
