[ECOS] Need Help--- For Porting RedBoot

[Subodh Kotkar]

Hi,

I am porting Redboot on intel PXA250. I have already ported ecos on same.
but it is giving problem during porting redboot, not even prompt of
redboot comes after building and loading bin file. I used hyper
terminal, and when i get connected it gives me garbage data such as
$T0a0f:30ca0050;0d:8ccd0000;#07  repeatedly when i press any key........
what is the reason??


If possible give me packages required for redboot porting other than
in redboot template..


Thxs in adv
plz if possible do it fast!!!

However, that's probably _not_ what you need right now. I'd rather focus on the reason _why_ GDB-stubs are entered. Try to find out how far in the initialisation you get. A BDM or JTAG debugger may be convenient for doing this. Some well placed diag_printf statements may also provide valuable insight.

It is not garbage data, it is GDB-stubs. Most probably, something goes wrong during startup, before reaching the redboot prompt, a processor exception is raised and caught by GDB-stubs which are now waiting for input from GDB.

If you get this far, a whole lot of things are already working: your serial communication seems ok, interrupts / exceptions are dealt with properly, your memory map most probably is ok.

Hth,
