Hi again, Soledad
I borrowed a OM13092 from a friend and repeated the tests with both "lpcxpresso54608_usb_examples_usb_host_msd_fatfs_freertos" and "lpcxpresso54608_usb_examples_usb_host_msd_fatfs_bm" demos and the failure remains.
I have tried both in High and Full Speed.
For High Speed: JP9: 1-2, JP10 open, JP11: 1-2, JP12: 1-2, JP13: 1-2, J1 powered by PC USB and USB Flash stick connected to J2, as described in board's User Manual.
For Full Speed: JP9: 2-3, JP10 closed, JP11: 2-3, JP12: 2-3, JP13: 2-3, J1 powered by PC USB and USB Flash stick connected to J3, as described in board's User Manual.
So far, I have tried it with 3 different USB sticks and one USB hub (making the connection bridge). It fails for all of them.
Sincerely I've never experienced something so weird and I think it is unlikely that two different boards present the same defect! Another intriguing point, as told you previously is that I used the same USB sticks in FRDM-K64F MCUXpresso SDK 2.2 demo and it runs fine for all of them. I need some light on it.
Thanks and best regards!
