Hello ,
I have some problem related to linux.
I m using linux-2.4.27 to build for arm architecture.
Earlier my arm board was operating at 60 Mhz.
Then my both serial ports were working properly.
Now i increased the frequency to 90Mhz.
Now only th debugg serial port (ttyS0) is working and the second uart port (ttyS1)is not working.
The max baud rate is 115200 kbps.Earlier at 60mhz i was able to communicate with ttyS1 at any baudrate ,i.e 9600,115200kbps.
Now The change i made is only i changed the AT91C_MASTER_CLOCK from 59904000 to 90000000
Not working means kernel is not getting started up.
I have checked all my settings.All are ok.
Plz help me to debugg this problem.
I will be very happy if u help me rgarding this.
Thanks & Regards
