How to use the spi on xavier

Hi teams I config the Xavier’s SPI0 as slave mode.Which communication with stm32， I set STM32’s SPI as master mode.The xavier SPI can receive data from STM32 , But can not send data ? it’s why The spi config of xavier as below: sudo ./devmem2 0x0243d010 w 0x00000415 sudo ./devmem2 0x0243d020 w 0x00000404 sudo ./devmem2 0x0243d040 w 0x00000444 sudo ./devmem2 0x0243d050 w 0x00000400 sudo ./devmem2 0x0243d058 w 0x00000448 my cmd:: ./spidev_test -H 1 -O 1 -s500000 -d1000000 -v -p aa…

SPI1 not work on Xavier

Please modify the pinmux for spi1 like spi2 does. file name: tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg SPI1 pinmux.0x0243d040 = 0x00000055; # spi1_sck_pz3: rsvd1, pull-down, tristate-enable, input-enable, lpdr-disable pinmux.0x0243d020 = 0x00000055; # spi1_miso_pz4: rsvd1, pull-down, tristate-enable, input-enable, lpdr-disable pinmux.0x0243d058 = 0x00000055; # spi1_mosi_pz5: rsvd1, pull-down, tristate-enable, input-enable, lpdr-disable pinmux.0x0243d010 = 0x00000059; # spi1_cs0_pz6:…
