Hello,

 

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. 

 

Any ideas?

 

Regards.
