I am working on the new revision of Slater (Rev. H) for VSM project. We have been extensively working on previous revision of slaters without any debug issues. However, the new revision of silicon has issues getting in to debug mode.
The security protocol related changes in startup.c have been taken care of.
The following warning message shows during debug...
: Warning: Stack pointer is setup to incorrect alignment. Stack addr = 0xAAAAAAAA
The same firmware when run on a previous silicon doesn't show this warning..
