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 Günter Leonhardt wrote: > > 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.
