Hi,
The AM572x datasheet contains the QSPI Board Design and Layout Guidelines.
I want to use Clock mode3 to connect to multiple QSPI devices.
In that case, is the R2 resistor shown in the figure below necessary?
Best Regards,
UNA

From the QSPI IO Signals table in the AM5728 TRM:
"In case Mode 3 is used, there is no need to connect the qspi1_sclk to the qspi1_rtclk."
In this case, the RTCLK is not used and therefore the circuit looping back the SCLK to RTCLK is not required.
