including old header file in new source file causes errors?

ECamino — Tue, 18 Jun 2013 21:08:12 GMT

Hi,

Suppose I have file a.c and file b.c. Both files include "file.h" Everything builds fine. There is a prototype in file.h I want to use in a new file, c.c. So I add #include "file.h" in c.c When I build, all the sudden the compiler doesn't like file.h anymore, which is an example file supplied by NXP/Code Red!

The errors mainly look like this:

error: expected '=', ',', ';', 'asm' or '__attribute__' before (prototype for func xyz)

Also, sturctures are flagged with an error.

Why does this happen? I'm probably overlooking something simple, but then the other two files using the same header build fine?

Sorry, not an expert at this!

LPC1769 Debugger/LPC1850 Target/LPCXpresso Error: Target Marked as Not Debuggable

janderson — Tue, 18 Jun 2013 15:55:50 GMT

Hello,

I'm attempting to burn some sample code I pulled down from the LPCOpen websire to my Hitex LPC1950EVA-A4 board via the LPC1769 debugger platform, but I keep getting the following error message within LPCXpresso:

I've seen users with similar issues, but their solutions either involved correcting a solder lead or something unrelated to my issues. These are pre-built evaluation boards I'm working with, not something that I've put together.

Any helpful input is appreciated. Thanks!

How do I create a clock using RTC internal LPC1768 by the CMSIS libraries?
Can anyone help me?

Hardware for programming lpc1769 using UART

karanmehta93 — Tue, 18 Jun 2013 11:05:58 GMT

Can any one help me to build a hardware to program the lpc17xx devices using UART0? The IC that I want to use is PL2303HX. Also can I get some procedure like the commands the the way to send it to the IC etc..
Thanks in advance.

Pin interrupt on Port 1, pin1

tyassin — Tue, 18 Jun 2013 10:15:06 GMT

Hello,

I try to generate an interrupt on PIO1_1, but as you can properly guess it is not working.
I have attached my code here:

Code:

void GPIO_int(void)

{

    /* Enable AHB clock to the GPIO domain. */

    LPC_SYSCON->SYSAHBCLKCTRL |= (1<<6);



    /* Enable AHB clock to the FlexInt, GroupedInt domain. */

    LPC_SYSCON->SYSAHBCLKCTRL |= (1<<19) | (1<<24);

    LPC_GPIO_PORT->DIR[1] &= ~(1<<1);    //Port 1, pin 1

    LPC_SYSCON->PINSEL[0] = 1 + 32;        //Interrupt Port 1, pin 1

    LPC_GPIO_PIN_INT->ISEL &= ~(1<<0);    //Edge sensitive

    LPC_GPIO_PIN_INT->IENR |= (1<<0);    /*Enable edge or rising level interrupt */

    //Enable registers

    LPC_GPIO_PIN_INT->SIENR |= (1<<0);    /*Enable Rising edge interrupt */

    LPC_GPIO_PIN_INT->IST = (1<<0);

    NVIC_EnableIRQ(PIN_INT0_IRQn);



}



void PIN_INT0_IRQHandler(void)

{

    LPC_GPIO_PORT->SET[0] = 0x10000;

    if ( LPC_GPIO_PIN_INT->IST & (0x1<<0) )    LPC_GPIO_PIN_INT->IST = 0x1<<0;

}

I have this ISR that should at least set an output pin high, but nothing happens.

If someone could take a look.
Thank you.

USB CDC Class Data transfer to host

saraswathi — Mon, 17 Jun 2013 14:44:15 GMT

Hi,

I have a LPC11U24 device connected to a linux host.This device works in USB CDC class. Once the data is sent from device to host using VCOM_bulk_in_hdlr, will the device wait for ACK from the host?

I have a situation where for the first read request from the host, the data is sent and received at the host. Immedietly if I send the second read request from the host, no operation happens at device. Also, if I try to generate interrupts from other IOs no interrupts get generated after first data transfer to host.

Can anyone please inform me does USB CDC mode operation of LPC11U24 requires ACK from host? If yes, what is the ACK format for linux.

Thanks in advance.

with regards
Saraswathi C

Hitex LPC1850EVA-A4 Build Error?

janderson — Mon, 17 Jun 2013 13:32:08 GMT

Hello,

I am receiving the following message immediately after my build has completed. Is this an error, or more of a warning message? Honestly, I am unsure whether or not the project has been built successfully.

Just for kicks and punches, I then proceeded to attempt to debug the project, and I am presented with the following message:

If 'Proceed' is selected, the following message appears:

Please excuse my ignorance - I am very new to this LPCXpresso IDE and hardware, so any help and/or guidance is appreciated.

Thank you.

LPC4357 Dual-Core programming error

wlamers — Mon, 17 Jun 2013 13:09:26 GMT

When programming the LPC4357 using a Red Probe+ and LPCXpresso 5.2.4 I get an exit error when programming the device from the GUI tool. The command line tool just hangs (at the same point).

First the flash area of the M4 (Flash A) gets programmed successfully, then the flash area of the M0 core (Flash B) gets programmed (also successfully). And then area just after the first Flash A gets programmed (only 76 bytes @ address 0x1A0016DC). But this is the points where the trouble starts.

I get an exit code -1073741819

I use this command:

Code:

What is going wrong here?
Strangely enough everything goes well when entering a debug session on the M4. Both Flash A and B get programmed, but the last area (where the errors are) is ignored. After a manual reset the program works fine, even without debugger.

BTW, version 5.2.2 of LPCXpresso shows no error programming, however the code itself does not run properly. Only when I first invoke a debug session (which includes automatic programming/flashing) the code runs properly afterwards (e.g. after reset/no debugging active). This is this case for both 5.2.2 and 5.2.4. Anybody from Code Red knows the cause maybe? What are the differences in programming/flashing between the debug session and the GUI tool.

Error 2 while Installing Link2 Driver with german W8 PRO / 32

R2D2 — Mon, 17 Jun 2013 10:53:52 GMT

Just tried to update a german W8 PRO /32 PC to LPCXpresso v5.2.4 [Build 2122] [2013-04-29].

Got a message:

Attachment 1059

and the driver isn't installed:

Attachment 1060

Trying to install it online or local failed:

Attachment 1061

Is there a known issue with german W8/32? Is there someone out there who is using this version and Link2?

Note: LPCXpresso is working without problems and LPC-Link. Anti-Virus & Firewall are off.

Problems Connecting to VM

ewajs — Sun, 16 Jun 2013 23:33:20 GMT

Hi,
I'm currently using a MacBook Pro running OS X (10.8.3) and I have a VM (via Parallels Desktop) running XP SP2 with LPCXpresso 5 on it, whenever I try to debug (on a non modified LPC1769 Kit) I get the same message:
"Premature end of file.:null(line:1, Col:1)"
And see that the VM is not detecting my board.
I'm working with another Windows based computers and had to install the VM because I wasn't able to import the Windows Projects on my LPCXpresso running on OS X (they were FreeRTOS projects).

Parallels Windows detects the board, but not the LPCXpresso on XP SP2. I could initially program the board in the Mac version of LPCXpresso but when I started using freeRTOS i couldn't import existing projects and make them work on the Mac version.

Thanks in advance.

Strange behaviour using my hardware.

cwpjr — Sun, 16 Jun 2013 23:09:57 GMT

My LPC1114FD/102 board is simular to the NXP 1114 board but without external xtal.

So I modified the UART demo to use the IRC and it downloads fine.

But it will not echo chars thru the uart until I disconnect the usb from the lpc-link (cut board). :(

Anybody see this?

My application using same uart demo code (w/o) interrupts works on NXP board.
On the nxp board it puts out a signon message and then does an interpreter...
Downloads to my hardware of the same code will also not respond until I disconnect the usb from the LPC-Link cut board, and even then does not put out signon msg or interpret.
Instead it just echos imput like the uart demo. Even after I erase flash and redownload.

:confused:

Hi,

Currently working on a diolan LPC4357 board rev C.

Does any1 already done it?
It's seems I can write something in the ram, but when reading, can't get the right value.

Any help is welcome.
thx, kabriolin

Clock & PLL config verification in tool?

cwpjr — Sat, 15 Jun 2013 19:27:38 GMT

Is there a way to verify clock and PLL speed and input selection in the debug session?

I'm changing clock stuff and the only notion of the tool noticing is during debug download; the assumed clock at flash download programming changes.

The peripheral views do reflect my clock / pll init values.

The reason I ask is that my changes should make things faster yet they seem slower!

realloc problem?

Lumos — Fri, 14 Jun 2013 22:11:09 GMT

Hello,
I am using LPCXpresso v5.2.2 [Build 2108].
I am trying to use realloc function from stdlib.h (Redlib - semihost).

For test I am calling this part of code in the loop:

void* ptr1 = NULL;
void* ptr2 = NULL;
ptr1 = realloc(NULL, 300);
ptr2 = realloc(ptr1, 301);
//free(ptr1);
free(ptr2);

When deallocation of ptr1 is commented-out, code crashes very soon.
But, in case free(ptr1); is commented, code is running without any crash.
From description of realloc function, old space should be deallocated automatically, but from this test it looks different. Manual deallocation is needed.

Can someone explain whats going on here?
Thank you
