Johann Fischer	53c33ab9b5	dap: add DAP backend USB The backend uses a new USB device stack and bulk endpoints. Only a single instance of the backend function is currently supported. Both DAP packet processing and the new backend are prepared to support multiple instances, but require a user interface and minor modifications. New backen has similar functionality to what is provided by the function in the sample samples/subsys/dap. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>	4 months ago
Johann Fischer	6fbd63b733	cmsis_dap: remove Kconfig option CMSIS_DAP_PACKET_SIZE We need a way to update the value configured by option CMSIS_DAP_PACKET_SIZE at runtime. For example, the USB backend may have different values depending on the speed at which the device is being enumerated. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>	4 months ago

Johan Carlsson	f5ccc3c82c	dap: do not return error in DAP connect command If a host client crashes or fails to disconnect, the probe will hang. Allow a new connection without raising errors.

Johan Carlsson	e46e72320e	dap: add Konfig option to set maximum packet size This also fixes a bug where the packet size returned was only 17 byte. Signed-off-by: Johan Carlsson <johan.carlsson@teenage.engineering>	1 year ago
Johann Fischer	7c9259abbc	dap: add CMSIS-DAP compatible controller Add CMSIS-DAP compatible controller which is a handler between the host interface and SWD driver. The controller follows CMSIS-DAP reference implementation. It expects a request buffer from the host interface, splits it to simple transfers and forwards to the DP driver, and finally returns a response buffer to the host. Interface to the host can be implemented with USB HID device support. Controller implements only SW-DP support and is tested with pyOCD and ADIv5.x.
