The J-Link is also compatible with any development environment that supports RDI, two examples are IAR and Keil. IAR supports J-Link with or without an RDI software license. Keil requires one. To use a J-Link with Keil you will need a J-Link RDI license from Segger. They offer thirty day evaluations at no cost. Joel

Hi I am new to the Phillips Arm I was gonna use the JLink from Keil for debug. Will this work?

You can only set hardware breakpoints inside the flash.

Hi, >Thank you for a very clear and comprehensive answer. > >It it so that, if you use Crossworks, you don't use OCDRemote anymore, >so Crossworks bitbangs jtag commands over LPT1 itself? Because >OCDRemote doesn't support hardware breakpoints... We've written our own parallel port device driver. Not because there's anything wrong with the Magraigor stuff we just prefer to have our own code. >Can Crossworks set as many breakpoints in Flash as you want? Are these >software breakpoints, or hardware breakpoints? Just two hardware breakpoints when debugging from flash, one of which is used (but not reserved) for single stepping. We are considering a permanent breakpoint feature i.e. flash breakpoint instructions on download. This feature won't wear out the flash (this is the main issue we see with reflashing pages to put in breakpoint instructions) but unfortunately the ARM7TDMI-S doesn't have a breakpoint instruction. Consequently one of the hardware breakpoints would have to be used to implement the flash breakpoint.

Thank you for a very clear and comprehensive answer. It it so that, if you use Crossworks, you don't use OCDRemote anymore, so Crossworks bitbangs jtag commands over LPT1 itself? Because OCDRemote doesn't support hardware breakpoints... Can Crossworks set as many breakpoints in Flash as you want? Are these software breakpoints, or hardware breakpoints?

Speed! They are much faster than a Wiggler (if the Amontec unit is used in Raven mode).

Hi all, I'm currently trying to find good and not too expensive tools for programming and debugging the LPC2148. I intend to use gcc as compiler. Can anyone describe what advantages Rowley Crossworks has over Eclipse+gcc+gdb? In addition, what is the main difference between the different lowcost (sub-150$) JTAG adapters? I understand that, with a Wiggler compatible product, the program is ran and debugged from RAM. This limits code size by the amount of RAM available. Are there low cost JTAG adapters that allow code to be executed and debugged in Flash? What do I gain if I use a Rowley Crossconnect or an Amontec debugger in stead of a Wiggler clone (for example the Olimex tool)? Thank you for all tips !
