I need to service my FlexCAN ISR in ~100us (the rate that fames can be received).
Presently, _int_install_isr is taking 184us to over 354us. FlexCAN interrupt level is 6.
Possibly can use _int_install_kernel_isr but I have never done a context switch in Freescsale, nor in c. Any examples for fast context switching?
Thanks very much!
