Hi all
Do you have some idea that we can have linux on cortex M series ....
as per our knowledge it has to be cortex A series ..pl CMIIW
i have attached the block diagram of simple data acquisition system that i have to work on with this mail .
please see that the right side portion of diagram (specially microcontroller 2) is only significant for us .
where we need to interface with few interfaces
1)USB
2)GPS, wired UART , wireless bluetooth --- as per my findings they all require total 3 UART s
3)OLED interfacing
4)SDCARD interfacing
5)NVSRAM interfacing
With your experience , kindly suggest which arm processor should we choose
Arm Cortex M3 series
OR
omap series which is arm cortex A series .
Just for information that we found Arm Cortex M3 LM3s9b96 from stellirsware its coming with safe RTOS ..
has all interfaces as required but but if linux is not installed on it
then it would be difficult for us to code for all these interfaces without OS .
please suggest a suitable solution...as per your experience with arm processors .
Thanks a lot for earlier reply

Googling should give you lot of good results.
Here are some links

Best part you can go through Texas Instruments Zoom products and download the source code to get known to it.

hope it will help you.

Hi all
We have got a work in which we have to realize a few communication interfaces like usb tcp/ip rs422 with arm processor
we chose arm cortex M3 .so we want to start learning arm cortex M3 programming in C .
Please guide if any one has experience in any arm microprocessors programming .
if possible arm cortex ...and if possible any of these interfaces guidance ....
pl tell how to start with ..any book any link doc is highly needed .
any forum mailing list for arm processors ...dat we can join ...
Pooja.
