hmm... sure i can start.. but people are not too much into OS right now.. and no1 ask about it.. we can start if we first try to implement freeRTOS on 8051.. make a small application running on it... then we can get people interest in this field.. so we can keep ARM aside and try to make 8051 RTOS application.. just any simple application..
what you say?

what you say?

that is the problem ajay..........
8051 is such a straight forward controller that u rarely ure rtos with it.....
still we can make a digital clock ( 89c51 (graphical lcd/16x2 lcd) rtc.....
just to compare the product with the one without rtos

lProgress is not made by early risers or hard workers, but by LAZY people, trying to find easier ways to do the same........

yes.. we are not bothered about what can be done with/without OS, but we are making something that will be an example of using RTOS.
so there is only one free RTOS there supported by all platforms which is FreeRTOS. but we also have to look for light weight architecture coz we are going to have no xram.

yes ,
but if somebody is using keil demo version
he can use rtx51tny/full with it.....
the code is small and does not require xram

just to feel what is happening

Nice work shyam,I think if u wana use linux u require 8MB RAM
and 16MB of flash which will only be possible in ARM 9 processor try some books on linux,because it will show u all debugging and compiling part. many books are available on net search in google.

Look towards the rising sun

no its not mandatory to have ARM9...
you can compile it for ARM7 too.. just make the right linker script to link the different sections and make file to get the hex file..
