I'm testing example project usb host msd fatfs with FreeRTOS in FRDM K66 with "MSD_FATFS_THROUGHPUT_TEST_ENABLE (1U)".
The problem is that the test fails with several FAT32 USB Flash Drives. For example:
1. TOSHIBA TransMemory USB 2.0 [7759,46 MB] (15155200 512-byte sectors): Test Write Ok, Test Read Fail.
2. Lexar USB Flash Drive USB 2.0 [16 GB] (31258624 512-byte sectors): Test Write Error, Test Read Not Executed.
3. Kingston DataTraveler USB 3.0 [7751,07 MB] (15138816 512-byte sectors): Test Write Ok, Test Read Ok.
4. Generic Flash Disk USB 2.0 [7780,43 MB] (15196160 512-byte sectors): Test Write Ok, Test Read Error.
Please see the below table for the list of USB devices tested with the USB Host stack. You also can get it from the release note.
Thank you for your feedback, I will send your issue to the develop team.
