[stive]

hi

i want to have both SDMMC 1 and 2

i test my project for SDMMC1 in 4bit sdio at 44MHz and no clock Div its work good single

but when i set SDMMC2 single with that not work

i change setting reduce frequency , use clock div , software pull up pins but it wait in F_mount and not work correctly

i check pinout of micro to micro sd for several time

but i can find whats problem i confuse...

I bought new uSD (sandisk ultra A1 32gig)

and not work too

but now in debug i see this result fast for fr_open --> FR_NOTREADY

in Previous uSD(toshiba EXCIRA 8gig) no any result back for FR_open (maybe go in the loop)

what can i do??

one bit SDIO not work in New uSD but in Previous uSD is ok
