Part Number: TDA4VM

Hi There,

On The EVM I want to try to create a MCSPI SLAVE in Linux SDK.

I found this documentation:

software-dl.ti.com/.../Overview.html

but I could not find any Information for MCSPI. Is there a sample Code for the MCSPI Slave on TDA4VM?

Thanks for the help,

Hi Yordan,

Thanks for the Information,

If I undrestand correctly it is not possible to use the Linux SDK Driver in slave mode.

Am I Right?

Hi Pouyan Azari,

There is support for SPI in slave mode in Linux Kernel 4.19, it is not regularly tested.

Look at Documentation/devicetree/bindings/spi/spi-bus.txt file in Kernel for salve mode info. You need to add a spi-slave property to spi node of dts to indicate it is in slave mode. You would also need to enable Kernel configs like CONFIG_SPI_SLAVE.

Vishal
