TMS320F2800152-Q1: Issues Writing to Flash :

Jobin Vijayan
Prodigy 10 points
Part Number: TMS320F2800152-Q1
Other Parts Discussed in Thread: C2000WARE, SYSCONFIG

Tool/software:

Controller : F2800152

C2000ware Version : C2000Ware_5_03_00_00

Issue : C28xx_CPU1: Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target.  Check your linker configuration and/or memory map.

The code functions properly in debug mode, ie, while running from RAM. I am using the standard cmd file : 280015x_generic_ram_lnk  without edit from C2000ware. However while trying to Boot from Flash,(280015x_generic_flash_lnk) I get the following error : 

I have added the Map file. 

Additionally I found that this error goes away when I comment InitPieVectTable(); from the main code. However, Obviously, the code wont work. The map file shows ISRs at  FLASH_BANK0_SEC_8_15 

I cannot find obvious issues in the linker file. Any help is appreciated. Thanks !

    Hi Jobin,

    This could be a GEL file issue, which CCS version are you using?

    Were you getting similar error when you run any C2000Ware SDK examples?

    Can you attach the map file for reference.

    Thanks

    I don't find an issue with the map file, can you upgrade to latest CCS12.8 version to get it confirmed if it is not a GEL issue or not.

    Also do you find the issue when you are building and loading any examples present in the SDK?

    Thanks

    Hello Aswin,

    I upgraded to latest version in between, but the problem remains. I have the same problem running example codes from flash for the same chip, 2800152. I don't have a problem for 28027 or 28069 

    Thanks.

    Hi Jobin, 

    Just for a confirmation, are you facing issue with SDK examples in flash configuration?

    Same error happens for sdk examples in flash configurations, only for 2800152.

    Hi Jobin,

    Let me try to reproduce the issue from our end, i will get back on this.

    So you are facing this error only in FLASH config and it is not happening in RAM config?

    we were able to run an example from flash into the device without any issues, did you make any updates in linker cmd file? we are using 12.8 CCS version with 5.03released SDK.

    Can you share the linker cmd for further analysis?

    Thanks

    Hello Aswin,

    Yes, I am getting this error only when running from Flash. I additionally tried to run the examples wit Sysconfig from C2000ware, with exactly the same result. 

    Once again, this error goes away when InitPieVectTable(); is commented.  Here is the linker script:

    Hi Jobin,

    in the map file attached above, i still see the ccs version as 12.3 - D:\ti\ccs1230\ccs\tools\compiler\ti-cgt-c2000_22.6.1.LTS\lib\rts2800_fpu32.lib

    Can you try creating a fresh workspace try out, as we were not getting any such warnings from our side - 

    Also you can see in the linker cmd file, there is no page related attribute, i think there is some error in the workspace. Please use a fresh workspace and try again.

    Also try removing FLASH_BANK0_SEC_8_15 from text section and try again to confirm if this is due to this memory location.

    If possible can you share the complete example in zip format so that we can directly look into them.

    Thanks

    Aswin
