According to the application note in SD Card Physical Specification: > The host shall set ACMD41 timeout more than 1 second to abort repeat of issuing ACMD41 when the card does not indicate ready. The timeout count starts from the first ACMD41 which is set voltage window in the argument. Previously, the timeout was exactly one second, and this caused certain larger-capacity cards to "time out", because they couldn't finish initialization process in time. |
