Subject: | [ts-7000] Avoiding task preemption by Linux kernel |

Hi, I'm developing an application (C code) on the TS7550 board, using Linux 2.6. I got an issue trying to use continuously the SPI bus for 20ms. Every 10ms, the communication is interrupted during about 0.5ms. I guess the Kernel scheduler interrupts the process. Do you have any idea to fix it? Could I change the tick rate of the scheduler so that it is about 50 or 100ms instead of 10ms? Could I prevent the Kernel from preempting the task during that critical section? Any idea would be useful :-) Many thanks, Dorian. ------------------------------------ Yahoo!
