Hi,

No the issue is not yet Resolved. we need some more links or support to do .

As other issues you mention in other posts are likely highlighting an HW issue on your board (shortcut, wrong connections, etc...), I think you should first resolve those one before going to boot trials.

Once you are able to do some ROM Traces (link in previous reply) on a stable HW, please share them if you need more insight on analysis.

Regards.
