TMS320F2800137: whether need disable Flash Prefetch before setActiveFlashBank in F2800137

BTW, customer firmware has not implement disable flash prefetch in F2800137, and also maybe interrupt run on flash, so far customer product has not issue happen, could you help evaluate if any risk on this condition?

This is applicable for F280039  device only.

Hi Rajeshwary

Thanks your advice, may I know the reason F2800137 has not this issue, and F280039 device only? How about the other C2K family? 

Hi,

Flash architecture for F2800137 is different from F280039 device. So this is not applicable for this F2800137 and other devices like F28P65x ot F28P55x.

Hi Rajeshwary

If customer firmware also implement disablePrefetch and enablePrefetch in F2800137, but they forget implement "__asm(" RPT #7 || NOP")" after enablePrefetch as below, but it seems required in SDK example code, is it any risk for F2800137 device?

Hi,

I don't see "__asm(" RPT #7 || NOP")" is call in our SDK example for F280015x device.Refer Flash_initModule( ) function in our example code.
