Hello.

1)Download LPCOpen examples. Run example simple webserver - it's work, but dualcore/dualcore_freertos examples not work.

These examples are made under lpс4330, I configured MCU settings settings changed to lpc4337 in LPCExpresso, but it did not help.

How do I start these projects?

P.S. Use NGX Xplorer LPC4337 board, lpcxpresso v6.1 and 7.

2) Are there examples of the FTP server for lpс4337?

Before running the example please make sure you have no valid image in your iflash [LPCOpen examples for NGX Xplorer is built for LPC4330 SPIFI Target], and the boot switches are set to SPIFI boot mode, power the board by connecting USB cable to USB0 [not USB1]. Note that the dualcore examples need images for both the cores [programming flash with only M4 or M0 will not work]

To run dualcore freertos webserver please follow the steps given below [Uses USB mass storage as the M0 image]

[list=1]
[*] Download the latest lpcopen package for NGX Xplorer 4330, from http://www.lpcware.com/content/nxpfile/lpcopen-software-development-platform-lpc43xx-packages
[*] Open LPCXpresso v7.0.2 and import [dc_freertos_webserver, dc_sa_msc_ram_m0, lpc_board_ngx_xplorer_4330, lpc_chip_43xx, lpc_board_ngx_xplorer_4330_m0 and lpc_chip_43xx_m0]
[*] Build project dc_sa_msc_ram_m0, click the Program Flash button on the toolbar and program the image generated "dc_sa_msc_ram_m0.axf"
[*] Build project dc_freertos_webserver and start the debugger
[*] Skip to step 10, if you have a working UART console [IP Address information is printed on UART, press Resume button in toolbar to continue]
[*] Open file dualcore_webserver.c and set break point inside function ip_addr_changed at the line that prints NET_MASK
[*] Use resume button in the toolbar to resume execution
[*] Once the board acquires IP address the execution will hit the breakpoint
[*] The IP address can be obtained by adding tmp_buff in expressions window, use Resume button in toolbar to continue
[*] Open a browser in the host machine [connected to the same subnet] type in http://[board IP address]
[*] You must be able to get the web page from webserver
[*] USB mass storage code running in M0 wil give access to index.htm which could be modified
[/list]

Note that you can run dc_sa_blinky_m0 as the M0 image in which case the webserver running on M4 will provide you with the default html page. It is also possible to run sa_freertos_webserver_m0 in the M0 core and dc_sa_msc_ram as the M4 image [in this case you must connect the UART to obtain the IP address or assign static IP address].

By searching internet for lwip ftp server I found http://www.crowproductions.de/lwipdev_en.php/ftpd.zip, we have never used this or tested you might have to use it at your own risk.

Can you explain better step 3 and 4 (if it is necessary to set the starting memory address for the Program Flash or other change we have to do). Because I have followed your steps but I get a Hard Fault when is starting the M0.

if (M0Image_Boot((uint32_t) M0_IMAGE_ADDR) < 0) {
while (1) {
__WFI();
}
}

hello
I am a beginner in lpc4337 and trying to make a project by this processor...
I want to blink the LEDs connected to P6.9 & P6.10 with core M0 and blink the other tow LEDs connected to P6.11 & P6.12 with coreM4.
I am working by keil 5 and registers without using of CMSIS standard function. my programmer is j_link and I have work on OPEN18xx/43xxB1 training board(fabricated by Wave Share).
by using your post and others I don't understand how to configure my program :((
I write this code for core M0 :

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#include <LPC43xx.h>

void delay_ms(int Del)
{
long int i;
for(i=0;i<Del*8000;i++);
}
int main(void)
{

//LED4 P6.9   GPIO3[5] FUNC0
LPC_SCU->SFSP6_9=0x00000028;
LPC_GPIO_PORT->DIR[3] |= (1 <<5);
//LED3 P6.10 GPIO3[6] FUNC0
LPC_SCU->SFSP6_10=0x00000028;
LPC_GPIO_PORT->DIR[3] |= (1 <<6);
while (1)
{
LPC_GPIO_PORT->SET[3]=1<<5;       // GPIO3[5] :   (LED D4)
delay_ms(500);
LPC_GPIO_PORT->SET[3]=1<<6;       // GPIO3[6] :   (LED D3)
delay_ms(500);
LPC_GPIO_PORT->CLR[3]=1<<5;       // GPIO3[5] :   (LED D4)
delay_ms(500);
LPC_GPIO_PORT->CLR[3]=1<<6;       // GPIO3[6] :   (LED D3)
delay_ms(500);
}
}

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
and setting for M0 core like this:

image1

image2

image3

image4

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

and this code for core M4 in the other project:

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#include <LPC43xx.h>

void delay_ms(int Del)
{
long int i;
for(i=0;i<Del*8000;i++);
}

/* Boot the M0 core */
void lpc43xx_m0_boot(void)
{
/* Make sure the M0 core is being held in reset via the RGU */
LPC_RGU->RESET_CTRL1 = (1 << 24);
}

int main(void)
{

//LED2 P6.11 GPIO3[7] FUNC0
LPC_SCU->SFSP6_11=0x00000028;
LPC_GPIO_PORT->DIR[3] |= (1 <<7);
//LED1 P6.12 GPIO2[8] FUNC0
LPC_SCU->SFSP6_12=0x00000028;
LPC_GPIO_PORT->DIR[2] |= (1 <<8);

while (1)
{
LPC_GPIO_PORT->SET[3]=1<<7;       // GPIO3[7] :   (LED D2)
delay_ms(1000);
LPC_GPIO_PORT->SET[2]=1<<8;       // GPIO2[8] :   (LED D1)
delay_ms(1000);
LPC_GPIO_PORT->CLR[3]=1<<7;       // GPIO3[7] :   (LED D2)
delay_ms(1000);
LPC_GPIO_PORT->CLR[2]=1<<8;       // GPIO2[8] :   (LED D1)
delay_ms(1000);

}
}

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
and setting for M0 core like this:

image5

image6

image7

image8

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
i should say that i use wizard project in keil 5 to make these tow project & i want to run all of these project by using any new heeder file or lib :~
i want to do all the necessary work like releasing M0 core from reset just by basic registers.
i read all of corresponsive post in this site and in internet, but i just confused !!!
thank you for attention
