Hi Serena.

Address 0x5F800 is for Flash Control regs, it is not a memory block, what are you writing to this address?

Can you check memory map of your compiled code to make sure it is writing to the correct memory address?

Hi Nirav，

we don't change the map any. but we found the issue because of the chip was very heat. maybe the chip was broken and we changed one new chip to instead , and it was working , issue was solved. Thank you !

about the memory block, could you give me more material to learn ? and I don't know how to change it to satisfy our needs if requiring in future .

Thank you

Serena

Hi Serena,

You will be able to find Memory Map section inside the Datamanual, also you can refer Technical Reference Manual for more details.

Also, we have C2000 Academy which provides basic information on getting started - https://dev.ti.com/tirex/explore/node?node=AOpze8ebskysmgASY3VKSA__jEBbtmC__LATEST

Let me know if you have any specific questions.
