Tool/software:

Hi,
I am using TMDS64EVM board. 

After sbl, 

during running the app,

I saw that garbage code dump  to my uart0.  that slow down my task.  I don't know where it came from, it is not from my application.  is it possible that SYSFW_TRACE_ENABLE or other core dump their trace.?  but I am pretty sure, I disabled trace. 


Thanks

.trace_dst_enables = 0,
.trace_src_enables = 0,


garbage example:   is below code familiar to you?

    Hello Jun,

    Can you tell me what all UARTs you have configured?

    Moreover, to parse these hexadecimal dumps, you can go ahead and use the system firmware python script.

    You can firstly go ahead and save the logs in the file sysfw.log in order to see the messages on the console. This way you can parse these hexadecimal logs.

    No this is not familiar to me.
