"Test Connection" fails when using CCS 20.x Linux with an XDS560v2 debug probe:

The value is '-708' (0xfffffd3c).
The title is 'SC_ERR_LIB_LOAD_ECOM'.

The explanation is:
Required dynamic library xdsecom3 could not be located.
The library isn't on the search path."

However, a successful debug launch using the XDS560v2 debug probe is still possible. The issue appears specific to dbgjtag via "Test Connection".

The issue does not occur on Windows.
