Hi Sir,

 

I have a questions about Supervisory Region2.

According to the TraveoII programming guide , I don't see the definition at address 0x17800000 - 17807FFF.

I just want to know do we need to support Supervisory Region2 for flash programming?

Thank you.

Jack

Hi Jack,

The SFlash region-2 (0x17800000-0x17807fff) will have same data and memory map as SFlash-region-1 ( 0x17000000-0x17007fff) (only SFlash update marker may differ- and that is non-programmable field anyways). If you program any region using WriteRow api, the other region is used as backup (in case anything goes wrong while programming, it can recover using other region image) and after successful program, the other region is updated with same data after reset. So, you need not to program both separately this as it's just redundant copy. 

Thanks,

Ashish

Hi Ashish,

 

Thanks for your reply.

As you mention, I have tested to program SFlash1, and then the content is backup to Sflash2. 

Thanks for great support.

@yush_4822876 

Our customer requires the Supervisory Region2  programming, and I have to confirm it on community.

Ashish has replied to me and solve the issues. Thanks.
