BSP lm3s6965
e...@e-bbes.com
anybody tried or is using it on real hardware?
Didn't work out of the box, so I'm trying to figure out where to start.
Sources from git as of yesterday.

No, I used this BSP only on the Qemu simulator.

You have to add the complete low level initialization.

I'm using the original EK-LM3S6965 board from TI, and browsing through
the sources, it looked complete. Could you give me some pointers what
I missed?
(or is missing?)
Thanks in advance

You can send patches for this to <rtems...@rtems.org>. Preferably in the
"git format-patch" format.

Sorry, I never worked with the real hardware. I hacked it together to get it
running on Qemu and did nothing more. You should review the complete BSP sources.

i can post my sources later.
P.S. i switched from RTEMS to freertos, so port is incomplete...

Please do ...
Thanks in advance ;-)

Short version of "why" ?

Which IP stack do you use on FreeRTOS? You can also use the lwIP stack on
RTEMS. For the basic RTEMS system 192k are more than enough (at around 32k
things get tricky).

Didn't you mix up something? The lm3s6965 has 256KByte Flash and 64
KBytes RAM ...
The biggest Luminary is (IIRC) the lm3sb9b96 with 512KByte Flash and
96KByte RAM.

Sorry, didn't notice that you started talking about STMicros ;-)

it is a port for lm3s8962, but I do not think they are very different.
