[quote="ukscone"]have a dig around in /proc/net

yes, i could do it in a clunky sort of way by using /proc/net/dev

thankyou

simplesimon

is it possible to read the network activity status via software? it would be great if there were something in /proc or /sys.

FOLLOWUP: I made some changes to my network, freeing up another usb ethernet adapter for use on the a+. all better now.

ok the pi is shot, ordered another. i disconnected the fuse, short was after fuse and open with respect to pp7 applied 5v there and led came on for a second and then the smaller die got real hot, still not sure what caused it, i actually doubt my original 5v to brass standoff conclusion the brass s...

i tried installing the kernel module with the mode=0 option, which puts the adapter in 10megabit half duplex mode. it didn't help.

simplesimon

yes, it is 9601, and therefore the cause of the problem, but a good driver module would not panic the kernel.

simplesimon

it happens when i wget kernel source from kernel.org too. i guess it is my cheap usb ethernet and the bcm2708 usb port are quarreling.

got my a+ today :) i had a problem getting it networked. the ip=x.x.x.x in cmdline.txt does not apply to my cheap chinese import usb wired ethernet adaptor. putting the address and such in /etc/network/interfaces fixed that. now it is up and running on the network but the kernel panics during apt-ge...

simplesimon

it is still doing great. i will keep an eye on it :) expect further damage to develop, the damaged card proves the negative voltage passed through the 3V3 regulator and will have damaged all that is connected to 3V3, such damage may not immediately be apparent, but I wouldn't trust the device. also,...

looking at the b+ schematic diagram I see an SMBJ5.0 transient voltage suppressor downstream from the "perfect diode" device. this operates very much like a zener diode. this is almost certainly where my 15 watts went.

simplesimon

did you clear the short circuit? if you did, did it then work properly?

simplesimon

I connected a 3 amp power supply to the 5 volt and ground pins of the header connector with reversed polarity, that supply went into overcurrent foldback and stayed there for about 30 seconds, and the only thing that fried was the sd card. I ordered a small switch mode regulator with builtin volt me...

simplesimon

i didn't know that the address and data busses are accessible. how to?

simplesimon

I'm not worried about it. My B+ plus is on the way and the schematics are too.

cbmbasic works too. the early version compiles without modification. in the later version just delete the arch lines in the makefile, the raspi's default will be used.

this might be the item of information that i need. is the only indication of a non-functioning root filesystem device a lit power led and nothing else happening? that is what i have. what does the directory of the root filesystem look like? mine looks nothing like a linux root filesystem (when i loo...
