What can we do to change these settings while running a program on the processor from the SPI setting menu shown in the picture?
Hello @peaces,
I assume that you are using the RDVCU5775EVM because you are not mentioning anywhere the board used.
For that, I've created the following model which is using custom code to change the mentioned parameters. In this case, you don't need to init and reinint the DSPI instance, just to update the parameters directly in the registers as in the below image. You can adjust the code as the sensors you are using requires.
Now, if you are using the blocking sending, the interrupt priorities must be increased, as I've done in the model using custom code as well.
Hope this helps,
Marius
Yes, I am using the RDVCU5775EVM board. The settings made are as in the image, but still, the problem is not solved.
Are you using the RDVCU5775EVM board? For the board, the SPI_2 PCS connection to MSDI and LSD is as the following screenshot shows.
Whereas I found your configuration of PCS both are 0, which is not reasonable. here is my configuration.
The MSDI and LSD both need complex drivers on top of SPI drivers. For RDVCU5775EVM, we have no MBDT demo but built an SDK-based demo.

What's the context of the System Update block?
If the code in the System Update block executes sequentially, it should add the function of DSPI_Deinit(2) between the two functions of DSPI_MasterInit.
it is recommended to set two different varables for the second parameter in DSPI_MasterInit, like DSPI_MasterInit(2, &spiMasterState_LSD, &spiConfig_LSD) and DSPI_MasterInit(2, &spiMasterState_MSD, &spiConfig_MSD);
Additionally, per the schematic of RDVCU5775EVM, the value of whichPCS in spiConfig_LSD shall be 3, and the value of whichPCS in spiConfig_MSD shall be 1.
Hello @mariuslucianand
As shown in the picture, there is a System Update block in two different subsystem blocks, and although we trigger these subsystem blocks to work sequentially, the settings cannot be updated and remain at the last configured setting.
