Hello everyone, I am having issue with listening for the logs from the debug UART for SIMtrace2. I run "make log" and I get: Sep 28 13:56:17 (@(@��(B(B(B�@B(B(B@(@(@��(BB(B(B(@(((B((@B(B�@(B��@(@�B(B(B(((B�(B(B(��@�� Sep 28 13:56:17 (B(�@@(@B(B�(��@(@�(B�@(B(�@B(BB(B(@(@B(B((@B(B((@@(�@B(B(B(�@�@�B(B��@B(B(B@(@ Sep 28 13:56:17 ((B(@(@@(@(��((B(B(B(�((B(�@B(�(B(B(BB(B(�@(B((B((B(B(B(B((BB(BR��(B(@(@@(B(�BB(@(@@( Sep 28 13:56:17 B(B(@�@(�(@(@@(@��(B(�(B(B(��(B(B(B@(��(B�@(B(B(B�@(@(@(@�(�(@@((B(�B(B@(@ I tried different setting combinations in stty, I tried minicom and picocom, and all resulted in either nothing being printed or more garbage, never actual ASCII logs.
