Does DAS support access to the HSM core?

[User20311]

I am using the TC234LP MCU, which contains an HSM (ARM M3)core. I have enabled the HSM BOOT in UCB and downloaded "HSMDemo.hex" into the program. I plan to use DAS to connect to HSM via MiniWiggler. Is this possible?

Hi User20311.  DAS is the driver for the miniWiggler, so in a generic sense, it supports HSM control.  But the important part is software support - what compiler/debugger are you using?  AURIX Development Studio does not support the HSM.  Commercial compilers do, as a separate license option.

i use arm-none-eabi-gcc. .

I have generated the "HSMDemo.elf" file, so this has nothing to do with the compiler.

I use trace32 to debug HSM well. so I want to try MiniWiggler to debug HSM.

How to do it？

You'd have to write something to have DAS configure the Cortex-M3 debug registers in the HSM.  Not for the faint of heart.

By the way, DAS is just a server, it communicates with MiniWiggler via USB, and interacts with IDE (like eclipse) via TCP port, similar to Openocd
