1. The problem explained I'm trying to use OpenOCD for something uncommon. Instead of connecting to the chip, I'd like to merely detect the chip. The procedure I have in mind would look like this:...

My understanding is that inserting software breakpoints involves replacing the next instruction in code to be executed by a software interrupt instruction which will cause the CPU to halt when it r...

I understand how JTAG used to be used as boundary scanner (very clean explanation at http://www.fpga4fun.com/JTAG1.html). However I can't see how JTAG these days is used as a hardware level debugge...

The standard (low-cost) way to program ARM microcontrollers is using Eclipse with a complex toolchain plugged into it. Eclipse has definitely its merits, but I'd like to feel independent from this ...

I have a strange bug in my code which disappears when I try to debug it. In my timer interrupt (always running system ticker) I have something like this: if (a && lot && of &...

I'm looking to do some hobby firmware development at home and need a device programmer. Hoping to keep to Open Source solutions, I found the OpenOCD project and also the Bus Pirate. For $30 i...

I am using an at91sam9260 for my developments. There is a Linux kernel running in it and I start my own software on top of it. I was wondering if I could use a JTAG debugger to debug the software ...

i'm working on debugging with gdb. i wanted to know how gdb works internally to set a brekpoint on an embedded processor through JTAG.

Ok, I am a little confused about programming for ARM processors. Barrage of questions time: How does one get the compiled binary into an ARM processor? Is JTAG the normal method (I think that is ...

In my embedded project am using JTAG interface to download the code and to debug the downloaded application. But I don't know what is happening inside the JTAG set up. Can anyone please give me bas...
