Ciao

I have a problem with my LPCXpresso LPC1769 and I hope someone can gently help me:

The unit worked for a month without problems, and was working the day before this problem appear. I had my problem at the beginning of a develop session and not after a modification of system.

When I launch debug, after build and some other connecting message I had an error window with this message:

15: Target error from Commit Flash write: Et: Flash driver not ready.

On console window some message flows but unfortunately they are cleared at the end when the error appear.

These are the steps that I made to try to recover
enlarging timeout editing scripts in debugger config
power cycle everything

I made also an attempt to just program the flash and this end to an error window:

05: File 'my_prog.axf' load failure: Et: Flash driver not ready

Enabling log i have this messages:

When all is working I remember a message in console or status bar about the assumed clock was 100.0MHz now I see 4.0MHz is here the problem ? Where this option can be changed ?

Thank you in advance

First of all I would always suggest to switch vector catch on and switch in ISP mode :)

See: http://support.code-red-tech.com/CodeRedWiki/DebugAccessChip

It's not unusual that a board refuses to work, but in general switching to ISP solves this problem.

If that fails, there's also a description about this error in:

Hi
I've had the same problem for a while.
I'm using a probe, not the LPC link. What I do is turn off power to the board, wait until it tries to flash the device (it shows "set timeout 6000") and then turn power back on.

If I start a debugging session when the board hangs on a breakpoint, reflashing is never a problem.

Figuring out this has been on my todo list for a while, but so has a ton of actual coding :-)

Do you have anything connected to the ISP pin?

As a first step, try starting the debug session with vector catch enabled in the Debug Configuration. From the console display, it appears the flash program succeeded, but a reset issue is preventing LPCXpresso from running your code.

As suggested I enabled vector catch and regained flash programming, after this I disabled vector catch and micro remain working.

I didn't made any further steps suggested because this first worked for me.
I will keep these other suggestion saved for the future.

Wonderful! I am again on the road.

Thank you everybody.
