hi, Can i know the Bf533 silicon version If it is 0.1 then u may face caching problems as it is provided in the Errata sheet of blackfin.The errata is as follows: Vectoring to an instruction that is presently being filled into the instruction cache may cause erroneous behavior [05000095]: Description: In some very rare situations it is possible that if you vector to the last 64 bits being fetched for a cache line fill, a random instruction will be executed. Vectoring can be in the form of jumps, calls, or returns. Because there is only a small timing window in which performing the above operation will actually cause a problem, it may be possible to run your code without the workaround and never see the problem. Workaround: When instruction cache is enabled. 1) Code written in C or C++ must not be configured as cacheable. 2) Code written in assembly must not perform any jumps, calls, or returns that have a destination within 32-bytes (same cache line), in any code configured as cacheable. Applies to revision(s): ADSP-BF533-0.1 If u have a higher version of silicon then u can try the attached code .
