RT1176 data transfer over USB2.0 interface

vinodnaik — Mon, 05 May 2025 05:10:03 GMT

Hi, We are using mcuxpresso ide and "mimxrt1170-evkb" bare metal firmware to transfer data over USB2.0 mass storage class. To transfer the 1 MB data, "mimxrt1170-evkb" processor taking approximatly 14 seconds, where as desktop system taking approximatly 9 seconds. We would like to improve the data transfer over USB2.0 mass storage class in "mimxrt1170-evkb". Please help me to resolve issue to increase or achive USB2.0 standard interface speed.

Hi @vinodnaik,

Are you testing with the "evkbmimxrt1170_host_msd_fatfs_bm_cm7" example code from the SDK? This example uses HighSpeed USB standard, and you can adjust the THROUGHPUT_BUFFER_SIZE for the data transfer buffer. Please try this example code and let me know if you are able to see an improvement in your data transfers.

BR,
Edwin.
