Subject: issues communicating with SPI on Raspberry Pi 3
Date: Wed, 5 Dec 2018 15:22:40 +0000	[thread overview]
Message-ID: <1544023361576.94285@mixed-mode.de> (raw)

Hi all,

I'm trying to communicate with a TPM 2.0 (infineon,slb9670) over SPI on a Raspberry Pi 3 in barebox.

CONFIG_SPI=y
CONFIG_DRIVER_SPI_GPIO=y
CONFIG_CMD_SPI=y

are set in the barebox configuration and

dtparam=spi=on

is set in the /boot/config.txt on the raspberry pi.

But when checking /dev/ on barebox, there is nothing related to spi except cs0.

I would have expected something similiar to /dev/spidev0.0 showing up.

Did I miss any configurations?

Best Regrds,

Kai Che
