void
)
{
return
USBH_USR_RESP_OK;
}
This called the initialization code a...
Posted on September 10, 2012 at 10:00Hi, have you resolved this issue? I am using the same code and USBH_MSC_BOTXferParam.CmdStateMachine is always 0 (corresponding to CMD_UNINITIALIZED_STATE), which makes it go through the default case in USBH_MSC...
Posted on July 13, 2012 at 12:06Hello, thanks for the reply. I tried again with the pull-up resistors in place. I often get SD_ILLEGAL_CMD returned by SD_ReadMultiBlocks(), for commands which seems to be valid. If I return 0 from the function, I am ...
