Our product develop is base on I.MX6 SOLOLITE+ BSP L3.0.35_4.1.0, I have a wifi module bcm43241, connect to slot sd2, sdio sometimes occur "mmc1:Timeout waiting for hardware interrupt" when in process of "mmc_add_host", reboot 100 times happen about 2 times,After track mmc driver, we found that there is no irq generate when host prepare sending command, we have tried cut down the sdio interface in wifi module side, problem still happen, only adjust the boot sequence of sdio and mipi lcm can fix this issue, which means let sdio init first , lcm init later, So anyone can help explain why?
