Hi!
I've encountered a recurring error while trying out MSC driver of USB Host example on FX3 Development Kit (CYUSB3KIT-001).
(AN77960 was my guide)
I've tried four different flash drives, and only one of them (2GB) got me response described in AN77960. One (2GB) got me only "Host connect event received" and "Host disconnect event received", the other two(8GB each) gave response shown below.
Host connect event received
Device descriptor received
Device address set
Config descriptor received
MSC device detected
Host connect event received
Application start failed with error: 74.
As it turned out after some debugging, error occurs because of an invalid CSW Signature
in CyU3PReturnStatus_t CyFxMscCheckCSW (uint8_t *csw) where csw[12] equals 1 in both cases.
csw[12] represents bCSWStatus field of CSW, thus bCSWStatus == 1 means "Command Failed", which gives me... no new information.
(http://www.usb.org/developers/docs/devclass_docs/usbmassbulk_10.pdf page 14)
All the drives are readable from Windows. I've tried formatting, just in case, it didn't help.
(Is there any list of flash drives compatible with FX3 Host Controller, maybe? If there should be one.)
Any tips or directions to the solution would be very much appreciated.
