(toppers-users 3548) Re: Issues on SafeG/NT-/T-ASP/IDEA6410 execution

[Daniel Sangorrin]

Dear Roman,

Thanks for your interest in TOPPERS/SafeG.

Regarding to your question, please could you try changing the
following lines in the file idea6410nt.h?

-#define VIC_MAX_PRIORITY   0x0
-#define VIC_MIN_PRIORITY   0xf
+#define VIC_MAX_PRIORITY   15
+#define VIC_MIN_PRIORITY   0

I wrote that code very fast and then switched to run Linux in the
Non-Secure side, so I think this was a bug on the priority settings of
the VIC.

Best regards,
Daniel
