Jlink固件的限制太多,还不如CMSIS-DAP方便。 Limitations
The firmware that makes the OpenSDA platform J-Link compatible has some limitations in contrast to an original, industry leading SEGGER J-Link:
May be used with ARM based Freescale devices only.
Only debugging on evaluation boards is allowed. Debugging on custom hardware is not supported and not allowed.
No production flash programming support.
Unlimited breakpoints in flash available for evaluation only.
