TMS320F280025: SCI BootLoader

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE

Hi all,

I was checking the sci bootloader example for f28002x . (flash_kernelex3_sci_flash_kernel). in this project , " FlashAPI_F28002x_FPU32.lib" is used for flash operation. Can i use " FlashAPI_ROM_F28002x_FPU32.lib" instead to reduce the code size ? if possible, what are the changes i have to made on the project ?

thanks

    Hi Sudheesh,

    You can use the ROM flash API.  Below snapshot taken from the flash API guide:  http://www.ti.com/lit/pdf/spnu631

    I will check with our SCI kernel expert to see if there is an example available.  

    Thanks and regards,

    Hi Vamsi, 

    I tried with ROM Flash API. For the first time it is working fine ( that is for the very first attempt after flashing the code ). but for the second time onwards It is giving errors like Blank error , programming error and verify error based on the optimization levels.

    I also checked the error code , it is 0x201 , Fapi_Error_FlashRegsNotWritable.

    Can you help me to sort this out.?

    thanks

    Sudheesh,

    Are you programming password to secure the memory?

    Hi, 

    No , i am just trying to flash an LED blinking code using this bootloader. I want know one more thing. The application works as intended if we start a debug session in code composer studio  , and giving error after a reset . Is there any special commands are executing during a debug session start  ( for unlocking flash registers ) ? .

    Thanks

    Hi Sudheesh,

    Reason for this error would be that the flash registers are not accessible due to security/lock status.

    Did you edit the LED blinking example OR are you using it as-is from C2000Ware? 

    Please attach the linker cmd file and the map file - we can check if anything is mapped to DCSM OTP space.  If needed, I will ask our security expert to look at your post based on your reply.

    Thanks and regards,

    Vamsi
