Problem solved!!! All my stupidity! Never assume anything.
My Problem was that JimStim? that I have been using in my MegaSquirt projects didn't have the same ground connections that MegaSquirt has. When I checked the JimStims? chema and corrected my connections everything looks fine at the moment. At least I'm able to connect the bord with megatune.
Sorry to everyone that I have troubled with my stupid user error.
Soldered EC36 and EC18, EC18-pins14&15 to MAX232
and EC18-pins14&15 to serial cable
Exact pin-pin end-end connections ? (obviously very important. Measure)
- DSUB9/2 ... Measured to SV2/2 OK!
- DSUB9/3 ... Measured to SV2/1 OK!
- DSUB9/5 ... Measured to GND OK!
- SV2/3 ... Measured to GND OK!
Soldered eight FETs, six IGBT-s and lastly the inductor 1R5 (from the rescue kit).
EC36/26 -> DB37/19, Corrected to DB37/1
EC36/5 -> DB37/18, Corrected to DB37/2
EC36/21 -> DB37/9,
EC36/22 -> DB37/10,
EC36/32 -> DB37/11,
EC36/25 -> DB37/28 ,
At this point I tried to get first connection with GenBoard.
Tried several methods to connect but didn't get any answer.
- Exactly ?'
- baudrate, command ?
At least try these:
- 19200,8n1 'S' command Shorted SV2/1&2, tried and nothing happened
- 9600,8n1 'Man' command No responce
- 9600,8n1 'S' command No responce
Loopback tested my serial port successfully.
To be sure that board is powered I measured the MAX232 and the processors Vcc voltage which was high as 10volts.
10 Volts ?? compared to what ? It should be 5 Volt compared to ground.
I made the assumption that when measuring voltage it's done compared to ground. Actually I tried several. GND on the chips and GND pins on the EC36.
It is measured, and tested (bootloader is uploaded via ISP, than several tests made via serial).
Bit curious about this. If the board doesn't have any connectors how is this done. How do you connect and power the board?
- with a special connector that has flexible needles, we call it "Pintester"
