Read Network mac address failed

#1

Hello,

is it possible to set a hardcoded mac address and not a random one?

Regards.

Kernel Log:

[ 6.832965] rk_gmac-dwmac ff4e0000.ethernet: rk_get_eth_addr: rk_vendor_read eth mac address failed (-1)

I have the same issue. (see dmesg output here: https://gist.github.com/peschuster/ffb738f5f911d35e79421c6d5a44177d)

Where is the MAC address supposed to be stored? The SPI flash is not populated on the board.
I can find 4 calls to “rk_vendor_register” in the kernel source: https://github.com/rockchip-linux/kernel/search?q=rk_vendor_register&unscoped_q=rk_vendor_register

The output from dmesg has two lines with “vendor storage”:

line 336: [ 0.466999] flash vendor storage:20170308 ret = -1
-> drivers/soc/rockchip/flash_vendor_storage.c#L306
-> _flash_read was not set…

line 431: [ 3.472590] vendor storage:20160801 ret = -1
-> I can’t find that in the kernel. The line was probably changed since then.

That’s what I got right now.

Thanks, but I don’t think that is related.
This issue is with the ethernet mac not being able to read or persist its mac address due to not initialized callbacks (see kernel output). Usual/planned address randomization is probably not going to end in kernel errors.

It’s the same with the wlan mac address. It’s a kernel problem and not a wrong network manager option.
