We use lpc1857.
We can download code to internal flash successfully but it is stopped after download. We set "reset and run", but why it can't start the code?

What type of reset are you using? Typically a Vectreset or Core reset works best.

We are waiting for solutions now. I may give so little information about this case. Here is more details.

Programming Done.
Verify OK.
Application running ...

Even it displays "Application running...", but nothing happens.

We can make it work in ULINK2 mode (code is starting at 0x1A000000).

Someone may experienced with this internal flash.

We set Vectreset.

Which board are you using? BOOTFAST in the PDL blinks an LED on the Hitex board. If you are usin g the Keil board you might have to change the LED port pin settings.

We designed our develop board. this code is running in RAM mode.If we start from debug mode, it is normal to start to run at 0x1A000000.

The problem is that we can't let it do "reset&run", after reset, it does nothing.

Before CGU_Init() try to insert this in your code.

LPC_CGU->BASE_M3_CLK = (0x01 << 11) | (CLK_SRC_IRC << 24) ;

Hi all,

I am new to NXP. I am using LPC Xpresso and MCB1800 development board.

I have compiled sample project for LPC1857 by changing the MCU settings under LPC xpresso.

I have change the GPIO setting as per MCB1800 board schemtic.

I am trying to run program from internal flash memory, but i am not able to achieve the same.

Regards,
Lalit Shah

Are you sure you have the boot mode jumpers set correctly?
