Trying to get SPI2 working on Jetson NANO Production Module

busch.johannes · September 20, 2023, 2:13pm

Hello,
I am trying to get our SPI working on Jetson NANO Production Module.
This thread was pretty helpful on getting started:

So basically I tried to change the device tree to the right pinmux and removed the GPIOs from the input fields.

I flash my new device tree using the ./flash DTB command.

I made sure my changes were effective since the REG dump changed.
Since above post is about SPI1 I cannot compare directly since I try to make SPI2 work.

Please note I am using this version: # R32 (release), REVISION: 5.0, GCID: 25531747, BOARD: t210ref, EABI: aarch64, DATE: Fri Jan 15 22:55:35 UTC 2021

PINMUX Changes:

spi2_mosi_pb4 {
				nvidia,pins = "spi2_mosi_pb4";
				nvidia,function = "spi2";
				nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

			spi2_miso_pb5 {
				nvidia,pins = "spi2_miso_pb5";
				nvidia,function = "spi2";
				nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

			spi2_sck_pb6 {
				nvidia,pins = "spi2_sck_pb6";
				nvidia,function = "spi2";
				nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

			spi2_cs0_pb7 {
				nvidia,pins = "spi2_cs0_pb7";
				nvidia,function = "spi2";
				nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

			spi2_cs1_pdd0 {
				nvidia,pins = "spi2_cs1_pdd0";
				nvidia,function = "spi2";
				nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_DISABLE>;
			};

GPIO changes:
Removed GPIO BB.0, B.4-7 and DD.0.

Are you using the custom carrier board for Jetson Nano?
Could you use the latest JP4.6.4(R32.7.4) to verify?

Please refer to the following thread for SPI loopback test.
Jetson Nano SPI Bus Not Working - #10 by KevinFFF

busch.johannes · September 21, 2023, 10:25am

I am doing exactly as in the thread. :/
I am just not doing Jetson IO Tools but instead I modified device tree like this. But I have the same reg dump now as in the thread.

We are also testing on devkit, since custom carrior board should be compatible.

busch.johannes · September 21, 2023, 2:03pm

If you can, please let me know which values you would expect from reg dump and gpio for Jetson NANO production module on nvidia devkit.

KevinFFF · September 22, 2023, 3:14am

The expected value for pinmux should be like the following.

$  sudo cat /sys/kernel/debug/tegra_pinctrl_reg | grep -i spi
Bank: 1 Reg: 0x70003050 Val: 0x0000e044 -> spi1_mosi_pc0
Bank: 1 Reg: 0x70003054 Val: 0x0000e044 -> spi1_miso_pc1
Bank: 1 Reg: 0x70003058 Val: 0x0000e044 -> spi1_sck_pc2
Bank: 1 Reg: 0x7000305c Val: 0x0000e048 -> spi1_cs0_pc3
Bank: 1 Reg: 0x70003060 Val: 0x0000e048 -> spi1_cs1_pc4
Bank: 1 Reg: 0x70003064 Val: 0x00006044 -> spi2_mosi_pb4
Bank: 1 Reg: 0x70003068 Val: 0x00006044 -> spi2_miso_pb5
Bank: 1 Reg: 0x7000306c Val: 0x00006044 -> spi2_sck_pb6
Bank: 1 Reg: 0x70003070 Val: 0x00006048 -> spi2_cs0_pb7
Bank: 1 Reg: 0x70003074 Val: 0x00006048 -> spi2_cs1_pdd0

Could you refer the steps and get it work on the devkit?

Bank: 1 Reg: 0x70003074 Val: 0x00006048 -> spi2_cs1_pdd0

This is my output. Using my JETSON NANO production module on devkit does not work with this REG dump.
I did not use jetson-io-tools, but do I understand it correctly that Jetson-IO-Tools will make this reg configuration automatically, nothing else, correct?

KevinFFF · September 22, 2023, 3:22pm

It seems the pinmux for SPI pins have been configured as expected.
Yes, Jetson-IO would do the same thing for SPI pinmux configuration.

Could your SPI loopback test work?

busch.johannes · September 22, 2023, 3:52pm

No. It didnt work. You have any idea what could still be the problem?

KevinFFF · September 25, 2023, 4:21am

Could you short MISO/MOSI and share the result of the following command?

$ sudo modprobe spidev
$ sudo ./spidev_test -D /dev/spidev0.0 -v -p "HelloWorld123456789abcdef"

Please also share the full dmesg for further check.

Do you connect PIN22(SPI1_MISO) and PIN37(SPI1_MOSI) on 40-header pins?

Are you using the following commands to get and build spidev_test?

$ wget https://raw.githubusercontent.com/torvalds/linux/v4.9/tools/spi/spidev_test.c
$ gcc -o spidev_test spidev_test.c

busch.johannes · September 26, 2023, 8:54am

It seems I used another executable from another thread. But result stays the same. I attached another picture showing the pins better. These are the correct pins, am I right?

Are you using Jetson Nano with eMMC or SD module?

Could you share the /boot/dtb/kernel_XXXX.dtb on you board?

busch.johannes · September 27, 2023, 9:00am

I am using eMMC Jetson Nano production module.
Here is the device tree zipped.

kernel_tegra210-p3448-0002-p3449-0000-b00.zip (40.9 KB)

KevinFFF · September 27, 2023, 9:41am

Could your Jetson Nano eMMC module work with Jetson-IO?

busch.johannes · September 27, 2023, 11:32am

I thought Jetson-IO is only for development boards, am I wrong?

busch.johannes · September 27, 2023, 4:31pm

On a newly flashed development board with Jetpack 4.6 after using Jetson-io, I got positive results.
I will try newly flashed production module with Jetpack 4.6 next.

KevinFFF · September 28, 2023, 7:22am

If your custom board design is similar as the devkit, you could also use Jetson-IO.
But it seems Jetson-IO is not compatible with Jetson Nano eMMC module so that you might need to configure the pinmux spreadsheet and apply them manually.

Okay, please verify with the latest JP4.6.4 (R32.7.4).

busch.johannes · September 28, 2023, 5:53pm

I made many tests now.

Devkit 4.6.4 using jetson-io
→ working.
EMMC 4.6.4 using jetson-io
→ jetson-io not working. Manually applying device tree changes did not have effect on spi register, so did not work. (I did not find out, why) BUT using compiled dtb from this thread About using spi on Jetson NANO - #69 by ShaneCCC
did work. I could not figure out what was different to mine, but there are many “diffs” but around spi it seems very similar.
EMMC 4.5 is the actual version I need.
→ I tried resetted dts to original nvidia. Then I applied the spi pinmux and gpio changes again. Pinmux changes do take effect, but spi_test is still not working. I tried to flash compiled dtb from above thread, but flashing device tree fails, because of the version missmatch I guess.
Is there any chance, you can provide me with such device tree for Jetpack 4.5? Or maybe even better: how to reproduce this device tree from original sources, since it seems doing something really good.

Thanks for your help so far!

busch.johannes · October 2, 2023, 8:24am

Do you still have ideas about what I could try next?
