Can you insert a print inside the kernel's card detection/removal interrupt handler and see the output? If possible can you share the code, so that it will be easier to debug. Up 0 True Down Jae-Hyun Kim 12 年多前 in reply to Renjith Thomas ...
eMMC Boot mode: No plan exists to support eMMC boot mode (at present). This decision will likely be revisited in the future. Some (untested, preliminary) support exists for boot mode in the VerilogeMMC model. eMMC Collision Detection:Collision detection remains an ongoing issue with eMMC suppor...

The card detection and other stuffs are available inside this function ( mmc_of_parse(host->mmc);). But still SD/MMC/eMMC interface is not mounting or creating the device. Any one can help why it is not detecting the device. I am trying to boot the Filesystems ...
