I'm trying to activate cspi1 on gpio 4-6 and 4-7 for sabre sd.
So i had in my board file :
But after the boot my line MOSI is high, if i understand well it should be low. In addition to this when i ask for a spi_write i dont see any signal on either SCLK or MOSI.
The only thing working is the Chip select.
I have to precise that i initialize also CSPI3 in my code but i dont have a way to test it.
Please help me to understand how do i have to setup my spi1 lines.
