Part Number: TMS320F280025

Hi,

I'm developing a firmware for the device TMS320F280025.

My current CCS version is "12.2.0.00009 ".

I've faced a strange behavior.

I'm using the CCS example "flashapi_ex1_programming" and it can be correctly compiled.

The issue is related to the output generated.

If I change the output format in ""BUILD / C2000 Hex Utility / Output Format Option" I get the following result:

BIN
FW correctly generated, attached in the zip "flashapi_ex1_programming.bin"
Here below the settings:
HEX
FW NOT correctly generated, attached in the zip "flashapi_ex1_programming.hex"
Here below the settings:
SREC
FW NOT correctly generated, attached in the zip "flashapi_ex1_programming.srec"
Here below the settings:

Here below the general settings in "BUILD / C2000 Hex Utility / General Options".

The firmware generated are in the zip attached.

fw_generated.zip

I noticed that the HEX and SREC fw compiled are missing one byte yes and one byte no.

You can check it by opening the file, but I try to show it better here below:

The same happens with the SREC file.

It looks like the file are cropped.

Is there a reason for this bug?

Is there an option in the compiler to get the HEX/SREC file with the same data as BIN file?

The likely fix is to add the option --romwidth=16. To understand why, please see this forum post. Though ignore the parts about the length of the line. That is not a concern here.

Thanks and regards,

Hi George,

Is this a workaround to use "-romwidth=16" or an intentional thing that at default it should be preset?

Otherwise I add that line as you can see:

The two files are different at the bottom:

Actually this is not a big deal because I can continue with my work, this was just my curiosity.

Best regards

No. The default is inherited from the predecessor toolchain for C28x, which started in the mid 1980s. At that time, a default of --romwidth=8 made sense. It does not make sense today. But we have learned, over the years, that changing a long standing default creates more problems than it solves.

Thanks and regards,
