Dear all,

I regularly have some trouble to start debugging using LPCXpresso 6.1.4 and LPCLink2.
I have different error usually something like

15: Target error from Commit Flash write: Ee(4C). Fatal Error

02: Failed on connect: Ep(01). Target marked as not debuggable

or the debug launch never finish (the run button is always disabled)

I have checked and my board is correctly powered and is working nicelly.

Do you have any idea why ?

Thanks in advance

Please check your debug/reset circuitry against:

http://www.lpcware.com/content/faq/lpcxpresso/debug-design

This ones

So we are talking about 'Design Considerations'...

I'm not sure which hardware results from this 'Considerations'.

Probably our ISP pull-up is not '10K to 100K Ohm' (or is it a potentiometer)?

Also a forgotten 'Consideration' is a Reset pull-up.

Anyway, it could be a good idea to rethink your hardware...

Hi thanks for your reply,

It's a custom board but we followed the design recommendation and debugging on it works most of the time.
Note that our firmware use the different sleep mode of the CPU.

Please find below the debug log. Nothing is missing it stop to this line and never go further...

Thanks in advance

What is your target board? Is it an off-the-shelf, standard board, or one of your own design?

What is your target MCU?

Please check your debug/reset circuitry against:

http://www.lpcware.com/content/faq/lpcxpresso/debug-design

How are you powering your board? Remember that programming flash requires additional power.

Please post the debug log from a failed connection…
