What is "JLink Info: Found SWD-DP with ID 0x2BA01477"?

Category: Hardware
Product Number: AduCM360/1/2/3
Software Version: Keil uVision

This is definitely a hardware problem on our end, but I hope someone can point me to the direction fix it, thanks!

We are working on new designs on ADuCm36x, and we have trouble with some boards, JLINK returned this "JLink Info: Found SWD-DP with ID 0x2BA01477" (sometimes without the lines about Found Cortex-M3....) . What could be the reason for this kind of errors when flashing the program?
