I need help with the LAN7430 chip. I have Jetson nano baseboard and I would like to use my own card with key E connector.
So… why this IC. Because of price, and future compatibility with PCIe 3.1 devices, also we hope in long term support
Yesterday I backported the driver for LAN7430 to the kernel 4.9.140 that Jetson uses (because support for this IC is as i know from kernel 5.0). I am able to compile and load the image into jetson, device normally boot as always.
I can see driver and module in /lib/modules/4.9.140-tegra/kernel/drivers/net/ethernet/microchip as lan743x.ko.
If i use command zcat /proc/config.gz
i can found see this line: CONFIG_NA743x=y
Unfortunately I don’t see anything with use lspci -vv except NVIDIA Bridge and Realtek ETH, dmesg is also clean.
We are using this schematic copied 1:1 (without EEPROM side):
My opinion is this must work. I have Intel wifi card for KEY E and it works fine. So i checked Intel pinout and compare it to pinout on my card. No differences.
All voltages are correct, clock is ok, so I’m very tired at this moment and i found this thread as my last chance to know something new, what can help me.
I will be glad for any tips.
