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

Hi Nidhi,
Even though this depends on a number of factors, I would
suggest an ARM9 CPU e.g. AT91SAM9XE512, because you’ll find a couple of Embedded
linux kernels for this CPU, this is going to save you a LOT of time trying to
port linux to someother unsupported CPU.
You also need to think about the Board Support Package, which
would include a bootloader e.g U-Boot and some lowlevel board initialization
etc.
Regards.
Sam.
