AM6442: Is it possible to connect 4 devices to OSPI using 4 CSs ?

Part Number: AM6442
Other Parts Discussed in Thread: SYSCONFIG

Hi,

My customer wants to confirm OSPI I/F.

OSPI has 4 x CS signal lines, so they think that four devices can be connected to OSPI I/F. Are they correct ?

Actually, they’re considering to connect two devices like below. Is this no problem ?

  1. OSPI NOR FLASH for Boot
  2. QSPI FRAM (or MRAM) for Data log used after boot

 

However, when they tried to configure the above by SYSCONFIG, they couldn’t add the second device on OSPI.

 

Again, is it possible to connect two devices using two CSs to OSPI ?

If it’s possible, could you tell them how to configure it on SYSCONFIG ?

 

Thanks and regards,

Hideaki
