CCS/TMS570LC4357: TMS570LC4357

Does CCS/TMS570LC4357: HalCoGen code cannot be compiled with GCC help?

Thanks Chester for providing this useful information.

We want the libc.a library with big endian and it should built by GNU compiler. Please share that library.

I installed GCC TI ARM compiler tools by clicking "Help->Install GCC ARM Compiler Tools" however all library files are in little endian format.

Also, there is no source code present to rebuild all the library in big endian format. Hence, we request to share the big endian format of library files from GCC ARM compiler suite.

e.g. "C:\ti\ccsv8\tools\compiler\gcc-arm-none-eabi-9-2019-q4-major\arm-none-eabi\lib\libc.a" is the location of one library file.

Thanks and Regards,

Please find link in Chester's post. 

According to the link in Chester's post, the below is the response provided in the forum however i am not able to access the available library from gcc-arm-none-eabi-7-2020-q2-update.

" The GCC ARM based upon v7.2.1 I re-built with big-endian run time libraries is available at gcc-arm-none-eabi-7-2020-q2-update. This includes the updated source, along with Windows and Linux executables. That is on my Google drive which I should have set to shared - let me know if it is not accessible.

I changed the version number to 7.2.1p1 to make it clear it is a modified version, rather than the standard version installed by CCS. If you install it in the CCS ccs/tools/compiler directory it should be discovered by CCS and be able to selected in a project as Compiler Version "GNU v7.2.1p1 (Linaro)":"

Could you please enable access or share the available big endian format of library files from GCC environment?

Basically, i want to use the function such as 'sprintf' and 'vsnprintf' from that big endian library file. In TI ARM compiler, these functions are available in libc.a(C:\ti\ccsv8\tools\compiler\ti-cgt-arm_18.1.3.LTS\lib\libc.a) file in big endian format. I want the similar kind of library file from GCC environment. Please help me to get this big endian library file or share the required source files of that library.

Thanks and Regards,

Hello Patchaiappan,

I am not able to access that page because of firewall. I will try later.

In https://e2e.ti.com/support/microcontrollers/hercules/f/312/p/907975/3362400#3362400 I attempted to summarise the changes to the gcc-arm-none-eabi-7-2017-q4-major source to add libraries built for Cortex-R big endian. The actual changes might be different for other versions of the compiler.

Thanks Chester for sharing the link. It is very helpful.
