Hi,

I compiled a small example using ADS compilers with Keil uVision3 for
LPC2148, set to be downloaded into the flash and debugged from there.
The compiled *.axf image ran fine with ULINK. Also when I loaded this
image into AXD, it ran fine (with OpenICE32 A900), as long as I gave
it the correct path to the source files.

So, I decided to take the source files and combine them into an ARM
Developer Suite (CodeWarrior) project. But even when I used the same
RO/RW base and entry point settings as in Keil for ADS, I couldn't get
the image to run. Debugging the firmware from the RAM was a breeze,
but I can't seem to get the right assembler/compiler/linker settings
for debugging it from the flash.

Even though in both cases (uVision3 and CodeWarrior) the same compiler
was used - the *axf file generated using uVision3 runs fine with AXD,
but the one generated using CodeWarrior doesn't. Any help would be
appreciated.

The following settings were used for different modes:

Debugging from RAM:
RO base: 0x40000000
RW base: 0x40000700
Entry Point: 0x40000000

Debugging from FLASH:
RO base: 0x00000000
RW base: 0x40000000
Entry Point: 0x00000000

Hmm...so I guess no one's willing to help me out here :)
Anyway I did a little googling and came across some threads saying
something about loading a flash programming script into the RAM first
and then loading the image you want to execute...so I'm still puzzled,
why does the image (axf) generated using ADS with Keil uVision3 work
with AXD?

Could be that nobody has anything to say. Not everyone runs keil software.
