Hi Pals,

I trying to program a custom board with JTAG programmer of my LPC1769 Stick.

If cutted the jumpers of J6 and placed a connection cable to my board.
I've checked power supply, and JTAG connections and there were ok but I get this message from IDE:
[B]02: Failed on connect
Target marked as not debuggable.
Emu(0): Connected. Was: None. DpID: EDB6. Info: WIN64HS12
[/B]
Any tips ?
Thanks in advance.
Gus

Check power.

Power is OK.
I've also read the article...

Any other clues ?
Thx in advance.

Now check it again. And again, until you find your mistake.

LOL.... :)
What does the error mean ?
[B]I also have this:
Error in final launch sequence

LPC1769 is SWD, not JTAG. Did you connect the SWD pins?

I connected the programmer like this:

[B]LPCXpresso board   -> Custom PCB[/B]
TMS (SWDIO)    (Pin 03 - J4 Connector)       -> TMS   (Pin 03) LPC1769
TCLK (SWCLK) (Pin 05 - J4 Connector)       -> TCLK (Pin 05) LPC1769
TDO (SWO)         (Pin 07 - J4 Connector)       -> TDO   (Pin 01) LPC1769
TDI (TDI)              (Pin 09 - J4 Connector)      -> TDI     (Pin 02) LPC1769
JTAG_RESET       (Pin 11 - J4 Connector)      -> TRST (Pin 04) LPC1769
GND                      (Pin 15 - J4 Connector)      -> GND

The LPCXpresso is connected and powered by the USB interface.
The Custom board is powered with its own power supply.

Wrong Reset connection :eek:

Minimal SWD is:

J4-3 SWDIO     - LPC1769-3
J4-5 SWDCLK - LPC1769-5
[COLOR=Red]J4-11 Reset        - LPC1769-17[/COLOR]
J4-15 GND        - LPC1769-GND

I've reconnected it but this seems not to be the problem...
.. but still the same prob.

Wrong Reset is a problem :) Obviously your hardware has still other problems :)

Is there any consideration to take advice for the first time you power a brand new processor ?
I mean, I just bought the LPC1769 and solder on the PCB.
For instance, does the oscillator may work the first time ?
Could I program the device via SWD for the first time or I should use ISP ?

Other Question:
The chip has 3 points over its surface (Labeled A-B-C in the photo). One of them indicates PIN 1. which one is ? (Information in the datasheet it is not precise...)

Thx...

:confused: I'm blind with this stuff....
Thx in advance to all...

Pin 1 mark is the little one, your LPC is soldered in correctly :)

A new LPC is empty, so it's starting in ISP anyway. Then it's working with IRC, so SWD and ISP are both possible. But of course using ISP via FlashMagic is a safer way to start. Just connect a Serial to USB converter and you know if your basic hardware (power supply, pullups...) is working.

If that's not working, your have a hardware problem (or used a wrong schematic):eek:

So your board is working ?

Yes.
There was a soldering problem. I've found it with a microscope :)
