"xdc_runtime_Text_charTab__A" in my const section

David,
in your Boot.cfg there are two commented out statements that include sizing.cfg.xs and then set up a minimal configuration. I can't tell which version of SY/BIOS you are using, so it's possible that commenting out those won't work. In that case you can add the following statements that deal with that array:

/* Error, Assert, Log strings are not loaded on the target */
var Text = xdc.useModule('xdc.runtime.Text');
Text.isLoaded = false;

Here is the explanation for that config parameter: http://rtsc.eclipse.org/cdoc-tip/xdc/runtime/Text.html#is.Loaded
