Re: [Gumstix-users] Robostix Modifications ...

[Cesar P. <ces...@gm...>]

Dave, I put th 10K Resistor on pin 4 of the gumstix connector to pin 3
of the UARTS, I then boot it up all three boards together and I was
able to ssh into it. I then went to the directory RS and did insmod
robostix_drv.ko and got no message back just the prompt again. I then
did ./uisp and got the following message:

NetFeed 1.0 >./uisp
Probably the AVR MCU is not in the RESET state.
Check it out and run me again.

In the wiki it says that probably forgot to install the jumpers
connecting the STUART port to UART-0, I cant find where these two pins
are located. Could you tell me where they are so I can connect them
together.

One more thing once I get the robostix "on" and do uisp --erase
--upload if=Flash-LED.hex, will that make the LED's in the robostix go
on and off right away? I have to re-boot it? I have to execute
afterwards in the robostix? Thanks!!
