I have a customised Imx6ull board. Imx6ull default uSDHC1 card detect is active low deafult but in our case SD card connector have active high card detect signal. So in my case till uboot only load after that error message will come. I have to make the CD_POL bit at uSDHCx_VEND_SPEC to 1 so that CD will become active high But i dont know where this change need to done. I think changing either in device tree or uboot will work. Anybody know where to change this bit?
