For some TTY interfaces no DB entry exists, which is reflected by
having a `None` in `tty[key]`. Trying to match a regex against `None`
in turn resulted then in an exception.
This fixes the issue by treating a filter applied on a non-existing
entry as not matching.
An alternative device configuration descriptor is required if multiple protocols, e.g. CDC ECM and RNDIS, should be used with same device interface. This commit is a prerequisite for the support of tinyusb netdev driver.
The commit includes the following changes:
- Remaining CONFIG_* symbols are moved to tinyusb_descriptors.h to be visible in all source files.
- Debug output is added to some descriptor callbacks.
- The conditional definitions of CFG_* symbols are changed to unconditional definitions to ensure that Kconfig CONFIG_* symbols are always used.
weact-f4xcx boards have only a single USB-C connector that is used for `highlevel_stdio` via USBUS CDC ACM so that it conflicts with tinyUSB for the moment.
Boards that are shipped with a DFU bootloader define the `dfu-util` configuration in their `Makefile.include`. However, when `riotboot_dfu` is used as the DFU bootloader, the board's `dfu-util` configuration must be overridden by the configuration as required by `riotboot_dfu` to use it to flash applications. Therefore, all `dfu-util` configurations are defined as overridable in the board's `Makefile.include` and the configuration as required by `riotboot_dfu` is included before the board's `Makefile.include`.
STM32F2/4/7 MCUs use sectors instead of pages, where the minimum sector size is defined by FLASHPAGE_MIN_SECTOR_SIZE, which is 16KB or 32KB (the first sector) depending on the CPU_MODEL. In this case SLOT0_OFFSET must be a multiple of the minimum sector size to cover a whole sector.
The `dfu-util` command uses `--device $(DFU_USB_ID)`, where `DFU_USB_ID` is derived from `USB_VID` and `USB_PID` to specify the DFU device to use. Without specifying `USB_VID` and `USB_PID` in the make command, `dfu-util` is called with `--device :`, which only works if there is only one DFU device. Also, the STM32 make system forbids the use of `dfu-util` as programmer without setting the variable `DFU_USB_ID`. Therefore, the documentation is changed to use `USB_VID`/`USB_PID` or `DFU_USB_ID` in the make command.
If the STM32 MCU does not have an internal D+ pullup and there is no dedicated GPIO on the board to simulate a USB disconnect, the D+ GPIO
has to be temporarily configured as an output and pushed down to simulate a disconnect/connect cycle to allow the host to recognize the device. This is done correctly in `cpu/stm32/periph/usbdev_fs.c` but not in tinyUSB STM32 hardware driver. That is, pressing the RESET button doesn't reset the USB connection.
