Forum Post: RE: atan gets a wrong result

I'm sorry, I cannot reproduce the problem.  Since it runs fine on the simulator, it is unlikely to be a compiler problem.  You should check that the values displayed in the watch window accurately reflect the computed values.  Try printing the values and comparing the results to what you see in the watch window:

#include <stdio.h> #include <math.h>  #define PI 3.1415926  void main() {     unsigned int i;      volatile double val_sin[21];      for(i=0; i<21; i++)         val_sin[i]=sin(PI*i/16.0);      for(i=0; i<21; i++)         printf("sin(%d*PI/16) = %f\n", i, val_sin[i]); }

Forum Post: RE: Combine DEBUG and RELEASE BUILDS

CCS only builds for TI, and not easily even when moving between TI platforms (6437, 6455, 6740, 6672, etc.), a make environment can build for all our platforms (including PC). What I can use is a specific make instruction to default to DEBUG build mode for the 674x platform, for one specific file.

When I break after the compilation hangs the following message appears:

 INTERNAL ERROR: C:\ti\ccsv5\tools\compiler\c6000_7.3.17\bin\cg6x.exe experienced a fatal internal fault

This is a serious problem. Please contact Customer
Support with this message and a copy of the input file

I have this in my script:

debugSession.breakpoint.add("blink.c", 34);
debugSession.target.run();
var Iaddress = debugSession.symbol.getAddress("i");
printTrace("address of i is . . . " + Iaddress);

It outputs: address of i is . . . 17402

i is declared like this:

volatile unsigned int i;

try putting volatile in front of yours to prevent optimization.

Forum Post: RE: EVM6678 emulator connecting error

Hi,

Based on the initial error messages I think the emulator was reporting back to CCS the device had a power failure on the connected cores (1, 2, and 0), while failing to write to a specific address in core 3. In my opinion it seems the baseboard of the EVM suffered a power glitch while loading code to core 3 (the one with the failed write).

The following error message, (the IcePick_D error) seems to indicate the emulator cannot be initialized anymore - if you are using the onboard emulator provided with the EVM, that could be a power failure on the entire board.

The third error message is just related to the fact you probably had the CCS debugger already launched, which causes the Test Connection to indicate the emulator was already "in use". 

Can you try to check the fist page suggested by Rajasekaran to better pinpoint the exact broken link in this setup?

Hope this helps,

Rafael

It's known now, only because of this thread.  It is in the queue to be fixed, but there is no schedule for it.  The function should not be inlined, but apparently it is in this case.  As to whether it is legal to have a function definition that is marked both weak and inline, I don't have the answer.

Shrenik,

You are not getting the included file that contains the subcircuits for the OPA336. Please check the names of the files that your are including and make sure they are present. The file on the web is named OPA336.txt, not .lib and that may be causing you an issue unless you renamed the file.

All of the errors are for missing Subcircuits that are not defined, but all are present in the file on the web.

I get the warning

directive does work for addresses below 0x10000. In addition I have set the Large Memory Model flag on the compiler, This must be for show only as I still must use the intrinsic _data20_ ... to read or write above the 64K boundary....

Any suggestions?

Hi,

I'm usingCCS5.4 and the TMS570.  I'm trying to printf, but it won't print variables.

 

If I do a printf with a literal string (printf("Hello world\r\n);) it works OK, but if I try to add printing a variable I get an undefined exception.

I have made sure I have full printf support marked in the project properties.

 

Thanks,

Hi,

Thanks for the prompt reply. The issue was as per http://www.ti.com/lit/an/sloa070/sloa070.pdf I only ended up importing opa336 and not its subcircuits. I just changed the txt to lib and carried on with create parts for library without importing 336. 

The 'subcircuit not found errors' are gone but there seems to be a convergence issue. I am just using a simple inverting amplifier configuration(attached) to make sure the models are working fine. The main error seems to be ERROR -- Convergence problem in bias point calculation. I have also attached the screenshot of the error. 

The library that I ended up creating is also attached.

If you can't get the compiler into large data model, you are in for a bunch of other problems, I'd expect.

As far as placing the section, you can do it the old way: give it a unique name with #pragma DATA_SECTION, and modify the linker command file to place that unique name where you want it.

The byte counts report is generated based on the info from the ELF program segment table.

If a loadable segment is a data segment, we increase the data byte count by the size of the segment.

If you simply tell the linker to allocate the memory region to hold the array buffer and nothing are needed to load to the target, the data count will not be increased.

Regards,

Raymond

MichaelH,

I have confirmed that the reference design works correctly in version 16.2, however, it does not converge in 16.6. I am not sure why the newer version does not work the same as the previous version. In order to get the simulation to run peoperly, please change the Maximum step size from 80n to 20n:

And set the following options:

RELTOL from 0.01 to 0.001, Transient time point iteration from 100 to 1000, and check the Use perordering to reduce... box:

The simulation should now run correctly as it does in 16.2.

[quote user="Franz Boeni"]I hope you understand my problem, and can do the same thing (Starter Kit B92 with the emulator of this kit). But please try with real different SW where the linker has complete different position of code. Only then you can detect the problem quickly.[/quote]I understand your problem, but I don't understand what is causing it (I can't recall a previous problem where the same symptoms).

I don't have a Starter Kit B92, so tested using a EK-EVALBOT with a LM3S9B92. CCS v5.5.00077 was tested on two PCs:

- Windows 8.1 64-bit with the latest CCS 5.5 updates - TI Emulators version 5.1.507.1

- Windows 7 64-bit with a fresh CCS 5.5 install - TI Emulators version 5.1.232.0

On both PCs was able to switch between two different programs being downloaded, with the correct program downloaded into flash.

[quote user="Franz Boeni"]Hope you will have a next idea.[/quote]1) Can you try enabling Debug Server Logging as per http://processors.wiki.ti.com/index.php/Troubleshooting_CCSv5#Debug_Server_Logging and attach the log file.

2) Can you zip up and attach the example ARM 'Hello World' project which you said previously demonstrated the problem, so we can check  the project and target configuration properties.
