Customizing DAPLink strings

There are a number of strings reported by DAPLink through USB descriptors, CMSIS-DAP, and USB MSD. These can be configured by a build or set in board and target info.

Preprocessor macros should be set in the yaml records for either the board, found under ./records/board, or the HIC, found under ./records/hic_hal.

USB descriptor strings

USB product string:
Macro: USB_PROD_STR
The value of this macro must include the string "CMSIS-DAP". Otherwise debuggers will not recognize the USB device. An example is the string used for micro:bit, "BBC micro:bit CMSIS-DAP".

MSD strings

MSD volume name:
Struct member: board_info::daplink_drive_name

URL file name:
Struct member: board_info::daplink_url_name

URL file contents:
Struct member: board_info::daplink_target_url

CMSIS-DAP string

CMSIS-DAP product name:
Macro: CMSIS_DAP_VENDOR_NAME
Not usually set.

CMSIS-DAP product name:
Macro: CMSIS_DAP_PRODUCT_NAME
Defaults to "DAPLink".

CMSIS-DAP v2.1 target device vendor:
Struct member: target_family_descriptor::target_vendor

CMSIS-DAP v2.1 target device name:
Struct member: target_family_descriptor::target_part_number

CMSIS-DAP v2.1 target board vendor:
Struct member: board_info::board_vendor

CMSIS-DAP v2.1 target board name:
Struct member: board_info::board_name
