Hi,

The answer is depends :smileyhappy: - is not only an answer here and I'll try to explain you why:

1. You can have a simple bare-metal application downloading in RAM that is also compiled for RAM addresses - this can be easily imported and use the download target set up the default RAM initialization file..and that's it.

2. You can have a more complex bare-metal application (like the u-boot) which is compiled to be written in a flash (contains NOR addresses for example) and then it relocates itself to RAM. In this case is not so simple to debug it, need to attach to it and to make sure using simple debug run-control operations (like step instruction) to not break the target.

Which is your flow? And what CW are you using? (PA, ARMv8, ARMv7..) ?

Thank you,

Marius

Hi, Marius!

I'am using CW PA and MPC8572DS board. I have an elf application wich starts from uboot. I have sources if this app, and i need to debug this app from sources using breakpoints etc. Where i can find tutorial wich contains "step by step" instructions?

Thanks.

Please take a look on this doc. It is not for PA, but it is applicable.
