Hi.. i found the similar case. So i wonder how i can resolve that.. But i didn't find the solution and i didn't know what problem.. i want to know that solution.. ->first card inserted (correct card detect) # mmc1: new SDHC card at address e624 mmcblk1: mmc1:e624 SU04G 3.69 GiB mmcblk1: p1 # # mmc1: card e624 removed -> second card inserted mmc1: error -110 whilst initialising SD card mmc1: Card removed during transfer! mmc1: Resetting controller. -> third card inserted mmc1: new SDHC card at address e624 mmcblk1: mmc1:e624 SU04G 3.69 GiB mmcblk1: p1 Regards, Jaehoon Chung Guennadi Liakhovetski wrote: > "divide error"???... hmmm, maybe one of SDHCI maintainers has to look at > it?:) > > Thanks > Guennadi > > On Mon, 16 May 2011, David Strobach wrote: > >> It's actually an oops.
