Hi everyone,
I want to test LPC4357 blinky. But when i downloaded my code, I got nothing from the board.
I used LPC43xx CMSIS in my code. my code is as below:

#include "lpc43xx_gpio.h"
#include "lpc43xx_scu.h"
#include "lpc43xx_libcfg.h"
#include "lpc43xx_cgu.h"

int main(void) {
unsigned long del=0;

SystemInit();
CGU_Init();

scu_pinmux(0xE, 7 , MD_PDN, FUNC4);
GPIO_SetDir(7,7,1);
while(1) {
GPIO_ClearValue(7,7);
for (del=0;del<15000000;del++);
GPIO_SetValue(7,7);
for (del=0;del<30000000;del++);
}
return 0;
}

I download my code on Flash Bank A. I appreciate if someone can help me

Hi ah1986,
Which tool are you using? You need to set checksum when booting from internal flash. In Keil tool chain
open options dialog box
Go to user tab
and run below command in "Run user command after Build/Rebuild"
Run1:
$K\ARM\BIN\ELFDWT.EXE !L BASEADDRESS(0x1A000000)
Run2:
fromelf --bin -o "$L@L.bin" "$L@L.axf"

Dear mc,
I put those command but nothing changed. I still don't see blinking LED.
I use Keil 4.70 for developing code & J-Link Ver.7.0 for programming and debugging

Hi ah1986,

Please try the examples from this link, it also contains a blinky which works out-of-the-box when running on an LPC4357-EVB board.
You should download examples1.zip and examples 2.zip, unzip examples1.zip to a folder (e.g. C:\LocalData\LPC4357-EVB), then unzip examples2.zip to C:\LocalData\LPC4357-EVB\Examples2.
Then open C:\LocalData\LPC4357-EVB\Examples2\GPIO\Gpio_LedBlinky\Keil\Gpio_LedBlinky.uvproj, build and download.

The project already has the signature generation configured.

Regards,
Wouter

Hi,

Try this ,

              GPIO_ClearValue(7,1<<7);
             for (del=0;del<15000000;del++);

      GPIO_SetValue(7,1<<7);
             for (del=0;del<15000000;del++);
