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?

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

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

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

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

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.

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 set Vectreset.

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

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.

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