CGT v4.3.7 Hex55 bug found on C5509A project

Other Parts Discussed in Thread: TMS320VC5509A

I am using TMS320VC5509A in my application and have recently moved from v4.3.6 to v4.3.7 of CGT.  The code needs to flashed to the target system so am using hex55.exe to created boot table.  Since migrating to v4.3.7 the target will no longer boot successfully as it had been doing with v4.3.6.  Made .out file using the v4.3.7 compiler as part of debug process, then used v4.3.6 and v4.3.7 of hex55.  Result was that using v4.3.7 of hex55 is creating the problem.

I created -ascil version of boot table so I could compare v4.3.6 and v4.3.7 outputs of hex55.  The .cmd file for hex55 is configuring registers prior to loading code/data.  The v4.3.7 boot table is missing most of the register configuration statements.  I am attaching .out, .map, .cmd for hex55, ascii versions of boot table for both v4.3.6 and 4.3.7 and an excel spreadsheet that analyzes the contents of the boot tables to show the missing register configuration statements. 

The .cmd for hex55 has multiple -delay statements which seem to causing problems for the v4.3.7 hex55.  Has there been a change in method of defining register configurations and delay counts?

Regards.

    Thanks for narrowing it down to a single version.  The only significant change for hex55 in 4.3.7 was to fix SDSCM00035366, which deals with --reg_config when it appears in a hex command file.  In short, --reg_config is processed after all other options.  I'll ask the author of the fix to look into this.

    This is a bug.  I have filed SDSCM00037783 to track it.

    Basically --reg_config is broken in hex55 v4.3.7.  Multiple --reg_config options will not work (only one is processed) and ordering between --delay options and --reg_config options is lost.

    Use hex55 v4.3.6 until this is fixed.  Since hex55 is a standalone executable you can copy hex55 v4.3.6 into your v4.3.7 environment.
