problem with spi_transceive between 1.4.9 version to 1.9.0 version

[Gal_S]

Hello,

We use pin 4 to set our CHIP SELECT in order to perform spi_transceive.

We use the SPI protocol to "talk" between a microcontroller and the LSM6DSL component.

It is important to note that on software version 1.4.9 it works fine and when we put it on version 1.9.0 it does not work properly.

I tried to take from a link that I saw in this forum and put it in our code but it does not help.

The only difference that exists is between the two DTS files of the versions.

Attached DTS file of version 1.9.0 :

Thank you very much - the problem was solved.
It is important for me to ask - why was there a conflict between the UART1 and the SPI1?
Why can both not run together if they are defined on different pins?

Glad to hear that it worked out.

Peripherals with shared instance (ie. same base address) cannot be used simultaneously, as described here:

Here's the instantiation list:

Kind regards,
