Could you boot up the device and share me the result of

cat /etc/nv_boot_control.conf

please put your pinmux change to tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi instead.

[wonderkay94]

1. cp tegra234-mb1-bct-pinmux-p3701-0000.dtsi to tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi
   (tegra234-mb1-bct-pinmux-p3701-0000.dtsi has modified)
   or
2. modify tx_pins rx_pins gpio_pins of tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi
   Is it 1 or 2 ?

tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi_patch (5.9 KB)
I modified the file Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi
It is the same situation.

[WayneWWW]

please read the register from jetson of each pinmux to make sure they are really set as your expectation.

[wonderkay94]

Hi
Attached are “cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups” and “cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinmux-pins”.

Our module is of devkit. Is it correct to modify tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi ?

[WayneWWW]

If you have concern, then try to get one commercial module too.

Your finalized product will be on commercial in the end.

[wonderkay94]

We only have the devkit module now. Is the pinmux correct ?

[wonderkay94]

Hi,
In file “Linux_for_Tegra/p3701.conf.common”. There are string “chip_sku” and “chip_SKU”.
Is it typo error?

[WayneWWW]

Please just go ahead using devmem tool + Orin TRM document to check the register.

There is no need to keep thinking the file is wrong or correct. Reading the resgiter will tell you it is correct or not.

What you did is not reading register either.

Attached are “cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups” and “cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinmux-pins”.

[wonderkay94]

HI
what register (address) should i check?

[WayneWWW]

Something as below thread.

Problem with RGMII Ethernet (88E1512) with JP 5.1.0 on AGX Orin (was working with JP 5.0.1DP and on Xavier)

I did find one relevant difference. PADCTL_EQOS_EQOS_TXC_0 is set to 0x00002050 for JP 5.1, while it is 0x00002400 for JP 5.0.1. Reading the TRM, 0x2400 makes more sense. As soon as I manually set it to 0x00002400, the Ethernet starts working! busybox devmem 0x02445058 w 0x00002400 I found that the invalid configuration of a completely different module (USB) caused the GPIO controller to grab pin E.00. I was not aware of the priorities of the gpio controller vs. pinmux. Good to know. Fixing …

[wonderkay94]

I can not use devmem2 to read register.

Environment PINMUX_CONFIG=“tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi” in file Linux_for_Tegra/p3701.conf.common. Is it correct for devkit module ?
I modify it PINMUX_CONFIG=“tegra234-mb1-bct-pinmux-p3701-0000.dtsi” and file tegra234-mb1-bct-pinmux-p3701-0000.dtsi. Then rgmii can work.
But there is error when power on mb1/mb2 state and work fine in kernel.

Have you solved this problem?

[wonderkay94]

Hi,
Now it works but semms have problem. Sometime it can not get ip when booting.
If no IP, use “ifconfig” command can see RX packets and TX packets is 0.
But it always has interrupts on “gpio 39 Level 2310000.ethernet:01”.
