Flipper Zero as CMSIS DAP/DAP Link
Flipper Zero as a Free-DAP based SWD\JTAG debugger. Free-DAP is a free and open source firmware implementation of the CMSIS-DAP debugger.
Protocols
SWD, JTAG , CMSIS-DAP v1 (18 KiB/s), CMSIS-DAP v2 (46 KiB/s), VCP (USB-UART).
WinUSB for driverless installation for Windows 8 and above.
Usage
VSCode + Cortex-Debug
Set "device": "cmsis-dap"
BluePill configuration example
{
"name": "Attach (DAP)",
"cwd": "${workspaceFolder}",
"executable": "./build/firmware.elf",
"request": "attach",
"type": "cortex-debug",
"servertype": "openocd",
"device": "cmsis-dap",
"configFiles": [
"interface/cmsis-dap.cfg",
"target/stm32f1x.cfg",
],
},

],
},
OpenOCD
Use interface/cmsis-dap.cfg
. You will need OpenOCD v0.11.0.
Additional commands:
cmsis_dap_backend hid
for CMSIS-DAP v1 protocol.cmsis_dap_backend usb_bulk
for CMSIS-DAP v2 protocol.cmsis_dap_serial DAP_Oyevoxo
use DAP-Link running on Flipper namedOyevoxo
.cmsis-dap cmd 81
- reboot connected DAP-Link.
Flash BluePill
openocd -f interface/cmsis-dap.cfg -f target/stm32f1x.cfg -c init -c "program build/firmware.bin reset exit 0x8000000"
Flash Flipper Zero using DAP v2 protocol
openocd -f interface/cmsis-dap.cfg -c "cmsis_dap_backend usb_bulk" -f debug/stm32wbx.cfg -c init -c "program build/latest/firmware.bin reset exit 0x8000000"
Reboot connected DAP-Link on Flipper named Oyevoxo
openocd -f interface/cmsis-dap.cfg -c "cmsis_dap_serial DAP_Oyevoxo" -c "transport select swd" -c "adapter speed 4000000" -c init -c "cmsis-dap cmd 81" -c "exit"
PlatformIO
Use debug_tool = cmsis-dap
and upload_protocol = cmsis-dap
. Documentation. Remember that Windows 8 and above do not require drivers.
BluePill platformio.ini example
[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
debug_tool = cmsis-dap
upload_protocol = cmsis-dap
