Hi All,

IDE: LPCXpresso v7.5.0
board: Custome board
OS: Windows 8
Actual MCU : LPC1759

When I try to debug I have the following error : No source available for "0x1fff0ba4"

The debug log is :
LPCXpresso Debug Driver v7.5 (Oct 21 2014 12:21:39 - crt_emu_cm3_nxp build 26)

Executing in bootloader.

The Pin P2[10] is pull-up with a 10K resistor.
I have tried also to regain control of debugging with the vector catch method, but unsuccessfully.

Does anyone have an idea what is going on here?

Thanks

I replaced the MCU and voilà, everything is now working.  ;-)

Thanks a lot.

Any idea?



Yes  :O

Connect a pull-up to the Pin (not the pad), ground the Pin and start a Debug Session.

Now you should be in ISP mode and after pausing the session MCU should stop somewhere in Boot ROM (0x1FFFxxxx).

In ISP mode P2.10 is an input, so release the ground connection. Now P2.10 is input and pulled high (with weak internal pull-up and) strong external pull-up.

If P2.10 is still low now, your MCU is damaged and it's time to use the next board  :)

Note: Of course I assume that you have checked all your supply voltages  :exmark:

If after a reset your code is not run (the processor remains in the boot loader), this can mean
- ISP is asserted (or floating)
- the boot checksum is incorrect (this is normally set automatically when the debugger downloads your code into flash, but if you are not using the debugger, you will need to write the checksum using the utility)
- there is no code in flash to run (have you checked that your code has been programmed into the flash?)

It sounds like a short cut but I have checked it.
I have desoldered the pin from the PCB and the pin is always low level.

Any idea?

... P2.10 ... is always low...



Sounds like a short circuit to GND on your board  :O

Hi R2D2.

I am scoping the signal at P2.10 and this pin (with a 10K Pull-up resistor to 3V3, with no more connections) is always low,
Regardless of the later configuration (input, output low, output high), sometimes I gain control with the debugger , sometimes (the most) not.

Thanks.

You're in Boot Rom (0x1fff0ba4)  :)

Check your project setup / code or use a simple sample...
