Hi Hank,

This is what worked for me :

Open up Putty, on the first page of options :
Select 'Serial' as the connection type
Enter the COM Port you are using ( eg COM5 )
Speed : 9600

On the right click on the bottom option ( Serial ... Under category )
Set Flow control to None
The other settings should be fine by default.

Back on Session save this session.

Now comes the bit you have to get in the right order:
Connect the SRV to your USB port
Load the session you just saved ... BUT DO NOT START IT
Switch on the SRV
Quickly Open the session in Putty and keep hitting the x key
until you see a menu then hit 'Enter'

At least that worked for me

All the best.

Richard

Are you certain you have the connector from the USB board going to the right signals on the 32-pin connector ? If you're connecting the ground signal to pin 1 (3.3V), that would likely cause problems.

Can this be done through any of the below listed means 1. wi-fi 2. USB to Serial port or do we require a JTAG interface. If we can flash the new source by methods 1 or two 2 , then what is the procedure that need to be followed.

This is explained at the end of the SRV-1 Blackfin setup instructions - http://www.surveyor.com/blackfin/SRV_setup_bf.html#setup3

You use wifi. You need to transfer srv1.ldr using the XMODEM protocol into the flash buffer and then write it to flash. From linux using telnet, type 'X' followed by ENTER. You should start to see a sequence of 'CCC' characters. Exit telnet, and run the following

sx -X -k -b -v --tcp-client 169.254.0.10:10001 srv1.ldr - or -

lsz -X -k -b -v --tcp-client 169.254.0.10:10001 srv1.ldr

Then restart telnet, and make certain you see a message like this -

##Xmodem success. Count: 33792

indicating successful transfer. If not, try the upload again.

If you had a successful XMODEM transfer, type 'zZ' followed by ENTER to write the firmware image to flash. If you were successful, you will see
##zZ boot image write count: 131072

At this point, you should be able to reboot the robot, and everything should be running correctly.

Hi
I just wanted to add my experience to this in case anyone else is as much as a klutz
as I am. I have to change the SVR configuration every couple of days, generally
it works fine over the WiFi but I have noticed that some times the power saving
mode seems to set itself and occasionally I would forget to change all the parameters
and this would render the robot uncommunicative.
I tried following the instructions here but it did not work for me, my soldering
skills were ok in 1975 but seem to have faded in time, I melted a number of
the four pin male connectors. finally I got Test Clip Adapters from Radio shack
and could hook up correctly. I'm not pushing RS, Jameco seem to have nicer ones
and cheaper ones called Micro test Clip and my next order to them will include
at least 3 of them.
I connected via kermit using the following .kermrc file

set line /dev/ttyUSB0
set flow-control none
set speed 9600

sometimes it doesn't seem to work but that is the xxx <return> timeing.
If you see any character you are in good shape, you just need to do the
off/on xxx <return> a few times. If you don't see any characters probably
the wiring needs to be changed.
I don't suppose anyone knows a source of the 4 pin male things with wires
already connected?
