Hi all, I have a sample led blink code running on lpc2368.When I build this code on keil uVision, it runs successfully.But when I tried with CrossWorks, I don't see any action on board.Is there a specific issue that I didn't know? Could anybody help me? ------------------------------------

Hi Guys, I have a strange problem. with the CTL(crossworks tasking lib). Have created two tasks , and hooked the timer0 for the task switching. every thing works fine if I program it using JTAG. but when I start the application by switching the power off and on then the application hangs when the ctl_taskrun is called. boot loader is running and it starts the application. ...

Hello People, I'm having a little setting up interrupts in crossworks. Reading the manual I found that i need to use: ctl_global_interrupts_enable(); ctl_set_isr(1, 0, CTL_ISR_TRIGGER_FIXED, isr, 0); ctl_unmask_isr(1); To setup the interrupt instead of using: void isr (void) __attribute__ ((interrupt("IRQ"))); & // VICVectCntl0 = 0x00000024; //use it...

I'm evaluating cheap compilers and it appears Keil is 16k limited for eval and IAR is 32 limited for eval. Both reasonably generous for learning I suppose, though I'm sure there are some gotcha's in there somewhere. So I'm also looking at Imagecraft's compiler (I've used them before with HC11 and PSoC) or maybe Rowley CrossWorks. I'm not worried about GCC's code density but I am worried t...

Dear Group, I'm trying to port a little projcet from a previous crossworks version to version 2.1 In there I have a routine to Enable and Disable Interrups which compiles fine in the old version, but not so in the new one. The code uses among other stuff the following two lines of code * asm volatile (" mrs %0, cpsr" : "=r" (retval) : /* no inputs */ ); asm volatile (" m...

While I am digging on my problem I figure I would throw it out to you guys too. I am using Crossworks 2.0 and the Segger J-Link tools on a LPC2388. My project has come along quite nicely until today. I added a SD Card driver that uses the GPDMA. The DMA uses the USB ram area. I added the following line of code to my project: static DWORD DmaBuff[N_BUF][128] __attribute__ ((section(".usbram"...

Is there a straightforward series of steps documented somewhere that one could follow in converting a GCC Eclipse project to Crossworks? They are both based on GCC so I assume the code is compatible but things like make scripts and memory map files would need to be converted. I'm hoping this is a fairly deterministic process that others may have documented and can refer to me to. - Chris...

Hi Group, I'm trying to use a Keil MCB4300 developper board along with crossworks. I downloaded the LPC4300 support package from Rowley and can create a little test project just fine. It compiles, but when trying to download this to the board the message pops up telling me that there is a "Target processor mismatch" which reads: The target processor defined in the project (LPC4357) o...

Hi all, I'm new to the Crossworks IDE/Envireonment and also to ARM7. I need to declare an IRQ handler function and I'm having troubles to do so. I looked up the GCC docs (I'm also also new to GCC...) and found the __attribute__ instruction to do so. However, the following code does not seem to be accepted by the compiler. void Handler( void ) __attribute__ ((interrupt ("IRQ") )); { ...

I'm starting a new project and I'm going to use either an LPC1300 or LPC1100 device. I use Rowley Crossworks 2.0 and have the following JTAG debuggers: Olimex ARM-USB-OCD Rowley Crossconnect Lite An IAR branded version of J-Link Luminary Micro LM3S811 Evaluation Board I am a bit confused about JTAG functionality on these devices. The users manual for each of these families indicates t...

I'm trying to get the LPCUSB VCOM example working using interrupts, but am having a strange problem. I have the Olimex LPC-H2148, Crossworks v1.6 Build 2, and a Wiggler clone for JTAG. Here's what I did to set up and modify the project: 1) Create a new project: Type: Philps LPC2000/Generic LPC21xx Board/Executable Target Processor: LPC2148 All other options default 2) in Syste...

Hi all, I'm having trouble here with making some sample code from NXP (the EMAC sample actually) work in crossworks. After first using the tasking library functions to setup IRQ I ended up in a situation where I could place a breakpoint within the ISR and execution halted. However, the system always hung sooner or later when debugging, stack was corrupted after calling the isr and all...

I'm trying to port some NXP demo code to Rowley Crossworks, it's written for Keil and has a cast on the left hand side of an addition. The Keil code has paramstruct *p; (uint8_t *)p++; p is a pointer to a struct 4 bytes long. I presume this is meant to advance the pointer 1 byte. Crossworks won't compile this - "lvalue required as left operand of assignment" The best I can come up ...

Hello everybody, I'm new to ARM7 development and I'm looking to compile and load my first test program on my Olimex LPC-P2138 development board. I'm evaluating the Rowley CrossWorks for ARM compiler/IDE. I've created a solution using the wizard and selected the MCU, Clock Speed etc and a project was created. However, I don't see a source file created the includes a stub for main(). So...

Hi Group, Is the malloc() (and free() for that matter) implementation as it's used in Crossworks irq save? I mean if I call malloc (or free) from within an isr routine (which eventually interrupts another ongoing malloc() ) will things go wrong? I haven't found that information in the docs (which does not necesairly mean its not there but just that I haven't found it). TIA Markus ...

How do you define a .text and .rodata for a c module in Crossworks? How do you add these sections to the flash_placement.xml file? I am trying to make a IAP boot loader code section that I can locate at the top of the LPC2129 flash range. I used : #pragma section text=".code_section" #pragma section data=".my_data" #pragma section bss=".uninit_data" I know how use to include ...

I am trying to use an FFT library in my Crossworks project. The FFT library uses malloc.h and memory.h but they do not exist in Crossworks. Is there a way to use to use this FFT library since malloc.h and memory.h don't exist? ------------------------------------

HOW TO DEBUG A PROGRAM THAT DOESN"T START UP IN CROSSWORKS ========================================================== 1. Ensure hardware is in the NOT-RUNNING STATE. 2. Attach JTAG cable and run CrossWorks. 3. Connect to the selected target interface (Target > Connect...) 4. Attach the debugger to the target (Debug > Attach Debugger). 5. Stop the CPU (Debug > Break). 6. Figure out where y
