How reported in the subject, I have two question about E310
I need that when the power connected to the board is switched on, the E310 boots.
Googling I found that is necessary to put an 1 in the file to obtain the result:
(using the command echo 1 > ....)
I tried but the board does not autoboot.
Linux ettus-e3xx-sq3 3.14.2-xilinx #1 SMP PREEMPT Thu 7 14:49:20 PST 2016 armv71 GNU/Linux
Linux; GNU C++ version 4.9.2; Boost_105700; UHD_003.009.002-0-unknow
2 DISCOVER IP ADDRESS
I used the E310 configured in DHCP.
Now, to know the ip address, I connect the console (screen /dev/ttyUSB0 etc.) and with ifconfig I obtain the address.
There is another way to proceed?
E.g. the command "arp -a", produce a list of ip address with related HwAddress of the machines connected on the same subnet.
I have a bash script that using the HwAdd of the E310 is able to report the ip address but in the list of arp -a the E310 appears only after you have connected to the board ,e.g. using the app putty.
The question is: there is a way to wake up the board in order to answer to the command "arp -a"?
Also others completely different methods are welcome!
