Other Parts Discussed in Thread: TMS470MF06607

Hi,everybody.

I am working on bootloader development for hardware having TMS470MF06607. There are some question about FLASH Copmact,erase and program.

The configuration of project as:

1. Build properties - Application binary interface (-abi) is eabi .

2. Flsh lib select  -pf035a_abi_eabi.lib

3. PLL Config -clk =80MHZ;  Pipeline mode enable;  Flash Data wait state =2;

4. Disable all the interrupts and exceptions during Flash operation

The problem is that ：The Function Flash_Compact_B Flash_Erase_B Flash_Prog_B  return false

    Song,

    Please change i (sector number) from 9 to 10. After that, you code will work.

    Reason:

    You can not erase/program the flash bank you are reading on. Sector 9 is in bank0. Your code is in Sector 0, which is also in bank0. That never works. This is one reason that you should copy your code to RAM if you want to erase/program sector 9. However, sector 10 is in bank1, so it works.

    Regards,

    Here, I modified your code, copy the code from Flash to RAM, now you can erase the sector 9 without any problem.

    4846.flash-operation-demo.zip

    This also answer the question how to copy code from Flash RAM in your email.

    Note: in the code, I use

    (&_Prog_run_addr) & ~(0x1). This might not be necessary in M3 because M3 is thumb code only. You can change it to (&_Prog_run_addr).
