Hello. I have been helped in this forum with the read and back programming TMS320LF2407. Please help you to read TMS320F2812 and write to the new one. In the datasis it is written that they have compatible source code. What addresses must be read for saving

    Kadirov,
    Are you trying to reprogram the image from a LF2407A “as is” on to a F2812? If so, it won’t work. There are some changes that need to be made depending on the peripherals you are using.

    If you are merely trying to copy the flash contents from one 2812 device to another, the procedure is similar to what I explained for LF2407A. The most important thing is that the original 2812 device is not protected with passwords.

    Hello Mr. Hareesh. I want to thank for the last time that helped me a lot with programming 2407. I just want to read 2812 and flash the new 2812. In 2407 there is a security bit at 0040h − 0043h, please tell me how to find out that 2812 is not protected, since there are two 0x3F 7F80 protection , 0x3F 7FF5 / 0x3F 7FF8, 0x3F 7FFF. If I'm not mistaken, then 0x3F 7FF8, 0x3F 7FFF everything should be zero. And the process of reading and programming a new one. thank

    Kadirov,

                Code security implementation is different on the F2812, compared to LF2407A. I strongly urge you to read chapter 2 in page 2-1 of SPRU078G. It is hard to explain how CSM works in a e2e post. It is a small chapter and should be a quick read. If you still have questions after reading the chapter, I would be glad to help you.
