Hi,
I got my srv-1 cam last week. I only have cam and breakout board, no matchport or wifi. these are my first steps.
I try to connect with a serial level converter based on MAX3232 which is powered from the 3.3V on the break out board. I use standard com port on my pc. windows xp.
- SRV1 Console only report "wrote 'I'" But no reply, no picture.
Then I tried to connect with Terminal program, no output at boot time, no response on any command.
Then I thought baudrate in srv-1 might be set wrong.
I used your sequence:
********************************************************************************
Note that if you are doing this recovery with a direct 3.3V UART connection at 115kbps, use these instructions instead -
1. Download a special 115kbps version of SRV-1 firmware from here -
http://www.surveyor.com/blackfin/srv1.ldr.recovery 2. Download and run
http://www.dolomitics.com/downloads/ldrviewer.html Load the recovery file
3. Remove jumper on 7/8, then power up Blackfin
4. Run UART Boot, uncheck 'Evaluate CTS'
click 'Test Port'
short pins 1/2
Click Autobaud
click Send DXE
wait until you see 'done' and you see the yellow LED's cycle
5. Put jumper back onto 7/8, close ldrViewer
6. Open up a terminal program with baud rate set to 115200, type V to see the version string displayed, then type X, wait for CCCC, then do XModem transfer of correct ldr file.
Wait until done, then type zZ to save firmware to boot flash sectors
7. Reset or power cycle Blackfin
******************************************************************
I used the srv1.ldr.recovery file.
Till step 5 everything went fine. Comport tested, Autobaud response: Blackfin replied correctly. DLH=0x01, DLL=0x1F, SCLK=44,1MHz. Then I sent DXE. This also seems to went fine. Then "done".
On the camera red led went on, after 2 seconds the two yellow ones went on.
But no response to step 6. No Version string displayed.
I still don't get a any response or output on my terminal program! Hardware connection should be fine as Autobaud replies correctly. Which terminal do you use? I use AVRterm
I use 115KBaud 8Bit No Parity 1 Stop in my terminal
With srv1Console still no picture.
Power is stable at 3,3V
What's wrong??? Any hints?
