Hi,

In my case i have installed breed boot loader every thing is working fine.

I have did some thing wrong while flashing from then router not responding to flash or reset.

Led status orange+blue (something like pink).

Can you suggest in this case.

In reply to BobDole. I think this depends on the status of the bootloader, check the LED status, if it accepts telnet connection, you should be fine

Can this method be used to flash stock firmware if the device is bricked? Or will this only work with OpenWRT

@scruss I found this

How much power can parallel port source
Comparision of different parallel port types
Normal UM82C11-C IEEE 1284 level II
Data output (>2.4V) 2.6 mA 2 mA 14 mA
Data line sink (<0.4V) 24 mA 24 mA 14 mA
Control output (>2.4 V) 0.5 mA* 1.5 mA ?
Signal lines (short circuit) 1 mA ? ?
Control line sink (<0.4V) 7 mA 7 mA 14 mA

but I don’t know what kind of port this is. It’s seems to be reasonable though. Second problem is that I don’t know yet how much the devices consume, but I guess I can measure it. Away from plotter now, so it’ll have to wait a bit.

above chart comes from this page which is definitely a valuable resource, but it’s talking about the host (PC) side, never about the plotter/printer side which might be a problem, or am I wrong?

In reply to scruss.

Interesting, the bluetooth isn’t exactly energy consuming, so it might work. I’ll look into it.

Just a thought: you might be able to power this from the plotter’s parallel port. It has a couple of pins that supply +5V. I don’t know if they can provide the necessary current, though

In reply to Doug. how do I test hardware handshaking? Will do the test if you want. K

Interesting, well done!
Does it support hardware handshaking?
