TDA4VM: TDA4 MCSPI master slave work at same time

Peiyang Guo

Part Number: TDA4VM

Dear experts,

Enviroment:sdk7.2+qnx710+custom board

We use mcspi0 as slave spi and mcspi1 as master spi to communicate with external MCU.

mcspi0 and mcspi1 operate in two different task.Both master task and slave task are blocked.

So I want to know whether MCSPI0 and MCSPI1 can work together？

thanks!

Hi,

Still confirming this internally, however I am not aware of any device restrictions on using McSPI0(master) and McSPI1(slave).

Hi,

Confirming that there are not device restrictions for the Main domain McSPI0 / McPSI1. They can be run in parallel, as required/configured by S/W.
