Other Parts Discussed in Thread: TMS320C6748, SYSBIOS

I worked on TMS320c6748.

And I am migrating program to BIOS6.

 

I just configed HWI, clock, timer, yet.

and found the bios always entered "ti_sysbios_family_c64p_hwi0", then the program is restarted over and over.

I want to know what  can cause such situation.

    Hi,

    Did you add the BIOS_start() function? It needs to be the last statement in main().

    the problem has been fixed.

    It has nothing to do with BIOS.

    the init process sequence have bugs.  which re-write code segments.

    thanks toddmullanix.
