TMS320F28069: Matlab 2021b C2000 build, .a2l file

abraham mathew

Hi:

I'm trying to build a existing model that was built fine in 2018a and trying to convert into matlab 2021b. Compilation was successful, but having an issue with the .a2l file being generated to be used for memory mapping with our controller. 2021b has a new way to generate these calibration files by a new menu item where it can generate the ASAP2 file by identifying the symbol file to be used for address replacement in the .a2l. The "generate calibration files" GUI only takes in .elf or a dwarf file for the symbols file. I used the .dwo file and it populated the right addresses for most items in the .a2l but the array elements are not recognized correctly. Anyone face a similar issue?

Using the 28069 chip with embedded coder support package for TI c2000 v21.2.0

Matlab 2021b version info:

MATLAB Version 9.11 (R2021b)
Simulink Version 10.4 (R2021b)
Control System Toolbox Version 10.11 (R2021b)
Embedded Coder Version 7.7 (R2021b)
Fixed-Point Designer Version 7.3 (R2021b)
MATLAB Coder Version 5.3 (R2021b)
Optimization Toolbox Version 9.2 (R2021b)
Signal Processing Toolbox Version 8.7 (R2021b)
Simulink Coder Version 9.6 (R2021b)
Stateflow Version 10.5 (R2021b)

Appreciate any leads,

Abe

Abe,

Can you let me know if we should group this with the other post https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1078265/tms320f280049-gmake-no-rule-to-make-target or if this is a separate issue? Since this appears to be a migration issue with the MW tools, I'll give the same input as the that post, you should get quicker support on MW forum https://www.mathworks.com/support/contact_us.html?s_tid=sp_ban_cs

Best,

Matthew

Matthew:

this is a separate issue and MW haven't been able to provide a resolution to generating a .a2l file. They provided link to the assembler documentation and suggested i generate a .pdb file and feed that into where the GUI asks for a symbols file. I havent been able to generate a .pdb file. are there steps i can look at to identify how to generate a .elf or a .pdb file using code composer studio?

Thanks for the help,

Abe

Abe,

I think that in the example above these are all MW related files, they may be using Visual C to generate their output files for the Simulink environment(agnostic of the C2000 target); i.e. the assembly they are referring to is not C28x/C2000 ASM so CCS isn't the correct IDE. I've asked the MW team to look at this post and comment as well.

Will see if others can chime in here.

Best,

Matthew
