Hi, I am learning to use I2C protocol and currently stuck with alternative solution. These are the details regarding what i am doing: 1) Using PIC 18F4580 AS master and PIC 18F4550 as slave. 2) I receive acknowledgments when i am debugging on the master side. 3) on the client side i do not receive any data from the master . 4) here by giving the code of master: #include

Dear all, I am an academic researcher interested of late in testing, debugging and static analysis of concurrent software. Two of the directions I am interested in are: (1) developing static techniques to prove that a certain piece of software is free of, say, deadlocks and data races, and (2) developing better testing tools for concurrent code, e.g, understanding what the right coverage c...

My problem is to test my driver software ,but the asic chip is not ready yet.I can simulate the registers of the asic easyly,but the HW interrupts which will be generated by asic chip is necessary to test my interrupt handler and interrupt driven SW. For X86 processor I know that also SW interrupt generation is possible but how? How should I write interrupt handler for a SW interrupt? Does...

Just created a project as type "application" and added a printf() call in main(). Executed this code in "M16C R8C Simulator" as Target. I referred M16C Compiler Guide chapter "6.4 Using printf for Debugging" and followed the steps to print the output in [View -> CPU -> Output Port]. The settings are same as mentioned in the guide but there is not output seen in output port window? I tried us

Hi Folks- I'm having a problem in which the OpenSTM32 System Workbench debugger reports ?Warn : no flash bank found for address 20000000?...

Hi Folks- I'm having a problem in which the OpenSTM32 System Workbench debugger reports ?Warn : no flash bank found for address 20000000? when I flash my STM32 target using System Workbench. The debugger then fails the binary compare process and prevents me from debugging. My linker script defines a memory region called DTCM which is mapped to RAM starting at 0x20000000 for 64K b

Greetings: I am helping a friend with a small battery charger project. I chose the Atmega88 for this project because it has a good mix of peripherals, memory size and physical size. I am using Winavr 4.11 to develop the code (which I found to be very easy to use) and a combination of AVR Studio, STK500 and JTAGICE mkII for debugging. I am having a hell of time getting AVR Studio to...

Hi, I am debugging s3c2410's usb device driver for linux, I have connect the VCC, GND, D+, D- and the usb device end can detect the insert/plug of usb cable. I installed a IRQ handler for the usb device and it can recieve some interrupt of reset when I insert the USB to host. But after the reset, no further interrupt happen. Even in the host side there are nothing displayed. I want to kn...

I am porting my Linux 2.4 code from an evaluation board with an MPC8275 processor and 8 Mbytes of flash, consisting of four Sharp LH28F016SCT-L95 flash chips, to a custom board with an MPC8270 processor and 8 Mbytes of flash, consisting of two Intel 28F320C3 flash chips. The custom board is crashing when mounting the JFFS2 filesystem. Specifically, with debugging on, in kmem_cache_alloc_on...

Hi, I try to debug function parameters inside a function. I am going nuts doing this. I don't know why I didn't notice problems before, but this is what I do. I have a function call myresult_t DoSomething(portSHORT command, portSHORT* status); I call this with portSHORT command = 0x0000; portSHORT status = 0xCCCC; (with portSHORT being 16bit wide) DoSomething(command, &status); ...

Hi All, I am working on a Renesas M16C Micro and I am having problems debugging my code.... I get a watchdog at a certain point in my code. I am unable to figure out where the watchdog occurs because the program counter points to special function register 0x000343. Is it possible that the program counter can ever point to a special function register? I thought it should always point t...

Hello, I have added a TFT controller peripheral to an already working Microblaze system with minimal implemented functionality. Now, I cannot access the data bus. Please see the error print out by XMD below. The new peripheral is connected via DCR bus for register access (slave DCR). There is a PLB2DCR bridge. It is also connected to PLB bus via its master PLB ports. Do you have any ...

Has anyone here had success doing this? When debugging interface between code running in the TPU (Time Processing Unit), and code running on the "68k" CPU, it would be nice that both stop and start syncroneously. According to the manual, this register contains 2 bits controlling freeze of the TPU. So, as I understand it, if I write e.g. 0x180 to DSCR the TPU should stop too, if the C...

I just finished debugging a FX2 board design and thought I would proactively post the solution to a problem that may bite other people. The FX2 has a pin called "reserved". The board designer left it floating instead of grounding it as per the FX2 design doc. Since it's called "reserved", it was easy to miss in design reviews - the name implies it should be left open. The error prevente...

Hi, I am trying to debug an embedded application, in which I have a pool of memory which is divided in fixed size blocks. In each block, there is a fixed size header and then some data. So all blocks are located linearly inside the pool. No my problem is that some other application writes its data in the header of next block, so my next block becomes invalid. And because of that when ...

I have a normal pc desktop machine with a msi k8t neo-v motherboard which utilizes an AMI BIOS. I have a pci video card in an expansion slot. On bootup POST, the BIOS complains about a routing table error on device 0:05:00 which pionts to my video card (the only PCI device in an expansion slot). This motherboard does not have onboard video so I need this video card in order to see anything (a...

comp.arch.embedded Atmel 328 external interupts I'm debugging an Atmel AVR 328 that won't generate an external #0 interupt. At present, the timer1 is generating an overflow interupt as would be expected. The input for the #0 ext. interupt (pin 4, d port #2) has been set to generate a mimic signal on another pin, which worked well. The setup for interupt 0 is: ldi areg, 2 ; extern...
