thanks Raghunathan R for your suggestion.... but my question is still there... why 8052 worked fine with the program compiled in one C language and it is not working fine with SDCC... i mean i have the same hardware on which i am trying to run both program.... once alway runs okey with the first power.... and second works once in 30 times power reset....

i agree it may be because of some reset problem but why not the same problem with the first C compiler


thanks
Shahzad
