I activated spi1 and spi2 with jetson-io (no other spi are shown there)
I modified my spi1 as slave as described in this post
ls /dev I can see
so I have spi0 and spi1 as I understand it. But not spi2.
Unfortunately according to the pinout, only spi1 and spi2 are on J41.
Why is spi2 not in
Have a check PINMUX xlsm file you should be able know it.
The pin 19,21,23,… aks SPI0_XXX aka spidev0.x
SPI1_MOSI 37 SPI2_MOSI
SPI1_MISO 22 SPI2_MISO
SPI1_SCK 13 SPI2_SCK
SPI1_CS0* 18 SPI2_CS0
SPI1_CS1* 16 SPI2_CS1
SPI0_MOSI 19 SPI1_MOSI
SPI0_MISO 21 SPI1_MISO
SPI0_SCK 23 SPI1_SCK
SPI0_CS0* 24 SPI1_CS0
SPI0_CS1* 26 SPI1_CS1
I had a look at the pinmux tables before. So are you telling me, that SPI1 in jetson-io (and on J41) actually activates SPI0 with spidev0.x and SPI2 in jetson-io and on J41 actually activates SPI1 with spidev1.x ?
Is the SPI1 in the dtb the SPI1 on the J41 (spidev0.x) ?
Yes, the pin19, 21 … is spidev0.x
