SPI Slave Select Connection Between AD2437A1MZ and SC594 SOMCRR EZ-KIT

Category: Hardware

Hi Team,

We are currently working with SPI tunneling using the AD2437A1MZ evaluation board and have referred to the schematics of both the boards.

Given this, we would like to clarify whether it is possible to use the SC594 SOMCRR as an SPI slave with the AD2437A1MZ acting as SPI master(highlighted portion in the diagram), considering that the  AD2437A1MZ hardware routes the slave select signal to SPI1_SEL2 instead of SPI1_SS to SOMCRR. 

Could you please confirm:

  • Whether SPI slave operation on the SC594 is supported with the AD2437A1MZ acting as SPI master, and
  • If so, whether any specific configuration or pin multiplexing is required to enable this setup.

If this configuration is not supported, we would appreciate your recommendation on the best approach to interface the AD2437A1MZ SPI master with the SC594 SOMCRR operating in SPI slave mode.

Regards,
Dns.

  • Hi Team,

          This is a gentle reminder regarding the query. We would appreciate it if you could provide an update on our query whenever convenient, as your clarification is required for us to proceed with our SPI tunneling implementation.

  • you should ask this over in the SHARC forum as it's not really an A2B question. Usually someone from ADI will reassign it but looks like thus got missed.  As an aside have this problem where a RPi is on the far end and had to solve it by putting a SPI flash that's shared by both the AD2437 and the processor; we use I2C to tell the processor who's actually controlling the SPI flash; in our case SPI is only being used for software updates and not live data (I2C is used for status, etc).
