I want to do one test about the fatfs,the function include LWIP/FATFS/UART/GPIO,the usb_host_msd_fatfs can work with freeRTOS,but failed when I merged it to the lwip_tcpecho_freertos example. the reason of failed was The USB enumeration failed when the FAT storage device connect to USB port.
I don't know how to fix it,could you give me some idea?
the source code show at the attachment.
SDK:SDK_2.5.0_EVK-MIMXRT1020，example: "usb host mad fatfs" & "lwip tcpecho freertos" .
IDE:MCUXpresso IDE v10.3.1_2233
HW：customer board(example 'usb_host_mad_fatfs' can work on it).
Thanks & Best regard!
