Hello,
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
With ls /dev I can see
spidev0.0
spidev0.1
spidev1.0
spidev1.1
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.
@ShaneCCC,
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) ?
