TMS320F2808: Export FLASH contents in a CSM secured chip without erasing sector A

Part Number: TMS320F2808
Other Parts Discussed in Thread: UNIFLASH

Hi expert,

My customer would like to read out flash contents in a CSM secured IC, they tried to read contents out after unlock with their password but get image with all zeros.

They tried in below steps:

1. Input the right password in "settings&utilities" menu in UniFlash and click on "Unlock"

2. Export binary image in "memory" menu.

3. Checked the binary image and find all contents are "zero"

Thanks

Hi Vamsi,

Kindly let me know if any updates on your side. I remember I didn't meet this issue in F280049, but F280049 store password differently.

Thanks

Sheldon

Hi Sheldon,

Can you have the customer enabled the "remain connected" setting and see if this helps?

Thanks
