SD Hotplug support in Altera Cyclone V SoC

Question

Hi all,  i’m not able to get any interrupt, and also not seeing any change in cdetect register while card is inserted/removed. :cry: Anybody faced such issue? is really hotplug is supported for sd on cyclone v soc? :confused: Please help...   Thanks &amp; regards, Keshava

The HPS memory map page describes cdetect as "Value on sdmmc_cd_i input port."

Can you tell me whether there is a dedicated HPS pin for that port to bring in the signal from the switch on the socket or if it can be routed arbitrarily via the FPGA fabric?

Thanks,
