- /sys/bus/mdio_bus/driver have not realtek driver.
How to add realtek driver in /sys/bus/mdio_bus/drvier ?
Please contact with Realtek which driver is for this one and check if the kernel source has it or not.
They say you can use the driver 8211F. The driver is included in nividia by default.
After talking with our hardware team, the reset pin should go from high to low, but when I took pictures using an oscilloscope, the reset pin started going low. Is there a way to raise that pin high?
Could you try to change the “0” in nvidia,phy-reset-gpio from 0 to 1 ? 1 means active_low.
I have a question.
Continuing with ./flash.sh jetson-agx-orin-devkit mmcblk0p1, the cam took too long.
So, can I just change the dtb file in /boot/dtb after ./flash.sh -k A_kernel jetson-agx-orin-devkit mmcblk0p1?
Orin kernel device tree by default is read from /boot/dtb. Flash A_kernel won’t have any effect to it.
So when replacing pinmux, do I need to flash the entire image?
When replacing “pinmux”, yes, please do full flash.
When replacing “kernel dtb”, no need to full flash. Just replace files under /boot/dtb.
I changed /boot/dtb but, It’s sill output low.
Maybe go to check the nvethernet driver and see if that gpio is got handled there.
please also check your current pinmux and gpio register of the reset pin. I already shared the address in previous comment.
I solved this problem. The cause was a hardware problem related to the PHY Chip. Thank you for your support.
