Hullo guys, I'm new to the LPC4357 , I'm using JLINK and KEIL .
Im just trying to turn on an LED with the following code :
.
.
void main ()
{
scu_pinmux(9,3,MD_PDN,FUNC0);
GPIO_SetDir(4,(1<<15),1);
GPIO_SetValue(4,(1<<15));
while(1);       
}
the problem is that after programming the flash, the code does not work and all LEDs are turned on but very dimmed . When I enter debugging mode , everything works fine . All LEDs are turned off and only the LED i chose is on .
What could the problem be ??

It worked !!
Everything was ok, except for a stupid missing pre-processing line to be written in the debugger menu.
I'm using Open43xx board from waveshare. :) :)

Hi Algorithm,
1) Are you using your own board?
2) Check reset pin
3) If frequency of operation is more than 90MHz please look into section 13.2.1 of UM. See below link
http://www.nxp.com/documents/user_manual/UM10503.pdf
4) Are you using LPCopen?
5) Can you also check TRST pin during boot?

Thx a lot mc for ur reply .
P2_7 is already pulled-up , which means it must boot from the internal flash .
I do not think its hardware issue now , when I turned on the board for the first time , it executed the demo code, which means that hardware is set properly. Im using JLINK , and i guess its software issue. When i start debugging then stop it , it keeps working fine . But still can not reset it on HW.

Hi Algorithm,
Could  you please check port P2_7. Can you pull it up if it is not pulled up?
