Dear Sir,
Moving to zephyr new installation 1.4.99
Configure SPI1,SPI3 . I can see the SPI configured in zephyr.dts
spi3: spi@b000 {
#address-cells = < 0x1 >;
#size-cells = < 0x0 >;
reg = < 0xb000 0x1000 >;
interrupts = < 0xb 0x1 >;
status = "okay";
label = "SPI_3";
compatible = "nordic,nrf-spim";
sck-pin = < 0x1f >;
mosi-pin = < 0x9 >;
miso-pin = < 0x1e >;
cs-gpios = < &gpio0 0x1a 0x0 >, < &gpio0 0xf 0x1 >;
};
spi1: spi@9000 {
#address-cells = < 0x1 >;
#size-cells = < 0x0 >;
reg = < 0x9000 0x1000 >;
interrupts = < 0x9 0x1 >;
status = "okay";
label = "SPI_1";
compatible = "nordic,nrf-spim";
sck-pin = < 0x3 >;
mosi-pin = < 0x8 >;
miso-pin = < 0x5 >;
cs-gpios = < &gpio0 0x4 0x1 >;
};
However the routine returns false
int spi_init3(void)
{
const char* const spiName3 = "SPI_3";
spi_dev3 = device_get_binding(spiName3);
if (spi_dev3 == NULL) {
printk("Could not get %s device\r\n", spiName3);
return 0;
}
else
{
printk("device %s is configured\r\n", spiName3);
return 1;
}
}
