I have added device qualifier descriptor to my usbcfg.c to be able to
pass USB2CV tests.
Code: Select all
/*
* @define Device Descriptor size.
*/
#define USB_DEVICE_QUALIFIER_SIZE 10U
/**
* @brief Device Descriptor helper macro.
*/
#define USB_DEVICE_QUALIFIER(bcdUSB, bDeviceClass, bDeviceSubClass, \
bDeviceProtocol, bMaxPacketSize, \
bNumConfigurations, bReserved) \
USB_DESC_BYTE(USB_DEVICE_QUALIFIER_SIZE), \
USB_DESC_BYTE(USB_DESCRIPTOR_DEVICE_QUALIFIER), \
USB_DESC_BCD(bcdUSB), \
USB_DESC_BYTE(bDeviceClass), \
USB_DESC_BYTE(bDeviceSubClass), \
USB_DESC_BYTE(bDeviceProtocol), \
USB_DESC_BYTE(bMaxPacketSize), \
USB_DESC_BYTE(bNumConfigurations), \
USB_DESC_BYTE(bReserved)
/*
* USB Device Descriptor.
*/
static const uint8_t vcom_device_qualifier_data[USB_DEVICE_QUALIFIER_SIZE] = {
USB_DEVICE_QUALIFIER (0x0200, /* bcdUSB (2.0). */
0x00, /* bDeviceClass (http://www.usb.org/developers/defined_class). */
0x00, /* bDeviceSubClass. */
0x00, /* bDeviceProtocol. */
0x40, /* bMaxPacketSize. */
0, /* bNumConfigurations. */
0) /* bReserved. */
};
/*
* Device Descriptor wrapper.
*/
static const USBDescriptor vcom_device_qualifier_descriptor = {
sizeof vcom_device_qualifier_data,
vcom_device_qualifier_data
};And have panic from usbDisableEndpointsI function:

1 <symbol is not available> 0xffffffec When I commented out lock/unlock calls on lines #420 and #427 in hal_usb.c than code
works as expected and passed USB2CV tests.
It looks like trivial bug but I am not sure because USB code in HAL is too complex for me.
