Hi,

InTIDA-020047 Two-device mmWave cascade reference design，QSPI D1 pull up with 10kohm resister externally，which is pull down internally in AM2732, is there a conflict with pull up and down simultaneously.

In a case of QSPI flash not be mounted，the pull up circuit will generate sink current from pull up source that may cause AM2732 startup failure.
