Hi everybody,
I'm debugging my LPC2378 project in Eclipse (GNUARM, OpenOCD, GDB
toolchain), and I don't see a way to view the various chip peripheral
registers (FIO0PIN, TOIR, U0THR, etc) symbolically. I can only view them using
the memory dump window by specifying the register's address, which is sort
of clunky. I can view registers r0-15 just fine in the register window.
Is there a way to view these registers symbolically in Eclipse?
Thanks...
Debugging in Eclipse - Possible to display Peripheral Registers Symbolically?

Hi,
In IAR I don't know of a way to do that either, except by memory dump, Maybe other debuggers can do it using symbolic variable names?
On another note, I am trying to migrate from IAR to Eclipse, and I am having trouble with the whole process. I must admit I am very new to Eclipse, so there is a learning curve there in terms of customisingit to ARM...
How did you go about it?
Thanks, Adrian

Thanks for the info, Adrian. I'm surprised IAR won't do this - my
experience using smaller micros like PICs and AVRs is different.
Regarding Eclipse, I used the various Lynch tutorials and they got me most of the way there pretty painlessly. I think they're available in the archives if you don't have them. I think the one I used most was "ARM Cross Development With Eclipse Components Revision3 March 17, 2006". The last steps were somewhat painful for me though - getting debugging to work and getting flashing to work over JTAG. That was a matter of getting the correct scripts which took me awhile and required searching the 'Net & digging into OpenOCD and GDB a little bit. I think I made a post on this list, that you can search for, with my final working scripts. Now everything works pretty well and I can get going on my project.
Good Luck...

IAR has a register view window which you need to turn on. (View->Registers). From there any of the internal registers can be viewed. All registers with bit fields have an exploded view so you can see what the bits are doing.
