That was the problem.
After GPIO configuration this line resolve the problem.
*setbits_be32(&immr->sysconf.sicrh, SICRH_GPIO_0 | SICRH_GPIO_1 | SICRH_GPIO_2);*
The DEBUG output:
SPI - CHIP SELECT CONFIGURATION &gpio = e0000c00 gpio->dir = 3f000000 gpio->odr = 0 gpio->ier = e0bfff0f gpio->imr = 0 gpio->icr = 0 *gpio->dat = e0000000 *
sysconf.sicrl = 0 *sysconf.sicrh = fc000000*
Thanks

Did you setup the System I/O Configuration Registers SICRL, SICRH?
I want to configure GPIOs on MPC8315, but I can't set the gpio. Below the configuration code and the output.
What is wrong?
