I need to find out what the *Pins 29 and 30* on Pin *Header P9* (SPI1_D0
and SPI1_D1) are.
Which is *MISO* (Master Input Slave Output) and which is *MOSI* (Master
Output Slave Input)?
I looked for that a long time but couldn't find it anywhere, can
somebody help me? That would be great!
Nice Greetings

Easiest way that I find is to look at the SPI DT. As you can see it shows:
spi1_pins_s0: spi1_pins_s0 {
pinctrl-single,pins = <
0x190 0x33 /* mcasp0_aclkx.spi1_sclk, INPUT_PULLUP | MODE3 */
0x194 0x33 /* mcasp0_fsx.spi1_d0, INPUT_PULLUP | MODE3 */
0x198 0x13 /* mcasp0_axr0.spi1_d1, OUTPUT_PULLUP | MODE3 */
0x19c 0x13 /* mcasp0_ahclkr.spi1_cs0, OUTPUT_PULLUP | MODE3 */
>;
};
spi1_d0 is INPUT, hence MISO, spi_d1 is output hence MOSI.
