SD on S32g rdb2 cannot generate insertion and remove interrupt

HangSong — Tue, 14 Dec 2021 07:27:10 GMT

Can't S32G RDB2 perform SD card plug-in detection through CD?

I am doing SD card support on S32G RDB2.
IRQSTATEN and IRQSIGEN write 0x17f00c3, enabling CINSSEN and CRMSEN.
When the SD card is pulled out and inserted, there will be no corresponding interrupt, and the register PRSSTAT[CINST], INT_STATUS[CINS] and INT_STATUS[CRM] will not change.

Thanks,
Song

uSDHC SD Card detect signals are not routed outside S32G2, this function is not
available on it.
