Hello Toradex Community,
I want to use a spi on a linux using the 4.14.8 mainline kernel. I’m using the Colibri T30 on Iris carrier board.
I build the kernel based on the tegra_defconfig and activated the spi_dev. In kernel and Devie-tree
To check the spi-communication i compiled spi-tools and spi-test.
I lopped the MOSI to MISO and the some test messages. To verify communication i connect
a oscilloscope and check signals.
The result is that Clock, MOSI and CS work as expected. But the spi-test only receive the first byte of the communciation.
After that i tried to the spi-gpio module. With the GPIO SPI all worked fine.
Has anyone had similar experiences or ideas that could help me?
