[yocto] Seeking recommendation for low cost dev board with Gigabit Ethernet that as a Yocto BSP

[Dimitris Tassopoulos]

Hi Bob,

I don't think that there's a JTAG but I guess you can use the serial port
for debugging. Personally, I'm just printing messages to UART with pr_info,
not even kgdb. But you may have different needs and I think that kgdb is
just a kernel option.

Regards,
Dimitris
