Hi Chris.. My question is others..I agreed the using frequency table.. But my questions is this... For example, if f_min is 300KHz, you can the below message. mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz mmc1: mmc_rescan_try_freq: trying to init card at 300000 Hz mmc1: mmc_rescan_try_freq: trying to init card at 300000 Hz In other words, first init card with 400KHZ, but second/third to init with 300KHz. i think not necessary that try to initialize the two times with 300KHz. I want to know your opinion..
