hi
I am working on powerpc(Mpc860T) with linux-2.4 kernnel,
As I am developping application using spi and with irqs:
For each 10 millisec I am getting siu interrupt(timer),In the
interrupt handler I have to read my device (using spi communication)
I am able to write it (I am able drive my device)
All other interrupts I am using are cpm interrupts(smc2.timer2,spi),one
siu interrupt for the present ,
I am facing the following problems:
1.No more spi read takes place : case-if i tried to do continous serial print using ttyS1(SMC2)
2. if I limited number of times of print then SPI read will not have probelm
How can i solve this with prbklem
thanks to all ...
