CCS/TMS320F28335: DSP/BIOSv5.42.0.07: C2Proj gives Sector violation (0xce50...0xce5f) for flash based application

Tool/software: Code Composer Studio

Hello,

C2Proj is giving a Sector violation (0xce50...0xce5f) for flash based application. I generated the ehx file the same way I did for a non-DSP./BIOS that I successfully downloade to the uC using C2Proj.

According to the map file, the following is located in that region.

.trace 0 0000ce00 00000200
0000ce00 00000200 --HOLE-- [fill = 0000]

That region seems like some type of trace buffer for the DSP/BIOS, which should be in RAM.

I was able to download and run the program using a JTAG debugger. Also, the program ran ok after removing the debugger and cycling power.

The disassembly of that region is shown below.

How do I fix this issue?

Steven,

C2Prog does not support loading to RAM. It can only load to Flash.

Debugger supports loading to RAM. However, even debugger does not guarantee loading to RAM when some sections of the linker are mapped to Flash. Any flash tools (TI or 3rd party) are developed to load a fully embedded flash application only - meaning all the initialized sections should be mapped to flash in the linker cmd file. If you need something to be executed from RAM, your application has to copy it from flash to RAM at runtime before executing it.

Please fix your linker cmd file to map all initialized sections to Flash. Let us know if you have any questions.

Thanks and regards,
Vamsi

Hello Vamsi,

I guess I didn't make myself clear enough. I already understood that the program had to be in flash.

The application code is all in flash memory as can be seen by the map file.

I didn't create any linker file for the project, so where is the linker command file that is supposedly created by the DSP/BIOS?

I need some help on understanding the DSP/BIOS so I can make a necessary changes.

Does this help: https://e2e.ti.com/support/legacy_forums/embedded/tirtos/f/355/t/272275?DSP-BIOS-TConf-creates-trace-and-args-as-Initialized- ?

If not, I will loop in other experts to help you.

Thanks and regards,

Hello Vamsi,

That might solve the trace section, but the initialize args section will still be there.

Has anyone found out how to solve both problems? Also, is there a template file I can change so I won't have to change the auto generated command file each time?

The post was in 2013, so I would think that someone would have solved it by now.

Stephen,

You can use the '--args=0' linker option referenced in Table 2-27 of the Compiler User's Guide for the args section.

I believe the template you are looking for is in your install directory here: "/bios_5_42_00_07/packages/ti/bios/config/cdb/c28xx.cdb". You will need to remove the 'fill=0' from the .trace directive in this template file. Let me know if this worked for you.

Hello Jas,

I removed all references to _traceString and _argsString and then tried to rebuild my project.

The rebuild generated the following error:

"C:\\ti\\ccsv6\\utils\\bin\\gmake" -k all
'Building file: ../tsk.tcf'
'Invoking: TConf'
"C:/ti/bios_5_42_00_07/xdctools/tconf" -b -Dconfig.importPath="C:/ti/bios_5_42_00_07/packages;" "../tsk.tcf"
subdir_rules.mk:35: recipe for target 'build-930243615' failed
js: "C:/MyProject//tsk.tcf", line 399: Failed to generate config files.
gmake: *** [build-930243615] Error 1
gmake: Target 'all' not remade because of errors.

Line 399 is the last line in tsk.tcf file and it contains prog.gen();.

It is interesting to note that the c28xx.cdb file contains the following information:

* Do not modify this file; it's generated from c28xx.cdb.h
* via mkseed!

Is it ok to modify c28xx_cdb.h? If so, how do I remove fill=0?

Stephen

Stephen,

The c28xx.cdb file does contain that warning, but you are able to modify it. You should keep the original though in case anything gets too out of whack.

For example, to remove fill=0 from the .args section you would just remove the "fill=0" shown below in bold from line 2220 of c28xx.cdb:

prop _argsString :: ("%8t .args: fill=0 {%12t\n *(.args)\n . += 0x%1x;%8t\n }\0, _argsSize")

You would do the same thing for the .trace section on line 11296:

prop _traceString :: (
"%8t .trace: fill = 0x0 {%12t\n_SYS_PUTCBEG = .;\n. += 0x%1x;\n_SYS_PUTCEND = . - 1;%8t\n }\0, _traceSize"
)

Hello Jas,

I removed both of them, but args fill = 0 still shows up in the map file, i.e.

.args 0 0000db6a 00000004
0000db6a 00000004 --HOLE-- [fill = 0]

Stephen

0 Jaskaran Atwal over 5 years ago in reply to stevenh

TI__Intellectual 1740 points

Stephen,

Could you try passing the '--args=0' linker option explicitly on the command line for the .args section?

Jas

0 stevenh over 5 years ago in reply to Jaskaran Atwal

Guru 20045 points

Hello Jas,

I tried to put --args=0 in the linker options and I think CCS replaces it with --arg_size=0 (see below).

I deleted the build directory and rebuilt the project. I can see the --arg_size=0 is in the console output when the compiler is linking.

The args section is still in the map file:

.args 0 0000db6a 00000004
0000db6a 00000004 --HOLE-- [fill = 0]

The project is using compiler version v6.2.11. Rebuilding with compiler version v18.12.2LTS produced the errors shown below.

Stephen,

There is an ARGSSIZE configuration parameter on line 2771 in the c28xx.cdb template that you may also have to change:

Could you try changing the '4' in bold below to a '0'. Could you also try removing the “if ($1 < 4)” statement shown in strikethrough below:

global ARGSSIZE :: 4 { /* words */

prop Type :: GCONF_NUMERIC

prop Format :: "0x%04x"

prop Style :: GCONF_SHORTSTYLE | GCONF_UNSIGNEDSTYLE

prop Label :: "Argument Buffer Size"

prop JSName :: "ARGSSIZE"

prop Visible :: 1 /* no support in scope yet */

prop Writable :: 1

prop NoGen :: 1

prop Set :: (

if ($1 < 4) {

.error("The 'arguments' section must have at least 4 words.")

}

else {

.ARGSSIZE = $1,

"ok"

}

)

}{

Let me know if this works.
