Part Number: PROCESSOR-SDK-AM64X
Other Parts Discussed in Thread: AM6442

Hi,

i am porting an existing project to AM6442 to run on the Cortex R5 core,

I am using MCU+ SDK (8.0) and basing my port on an example using free RTOS.
code composer 10.

the example files come with TI Clang toolchain and so is the linker file.

i would like to change the toolchain to GNU due to previous project used GNU also and porting is much smoother.

Are there GNU examples for the Cortex R5?

Thank You!

Hi Peter,

As discussed over call, we were able to run sanity example with gcc. Full support for gcc will be shared via patch release on end of next week (13th Aug). Meanwhile, I will do feasibility check for getting reference linker command file for you.

Hi Prasad,

i believe that i would also need the start up files for GNU,

the files i know of from the SDK:

* boot_armv7r_asm.S

* autoinit.c

* autoinit.h

maybe the ones for freertos:

* HwiP_armv7r_vectors_freertos_asm.S

* portASM.S

Best Regards,

Hi,

i tested you GCC example project named "hello_world_am64x-evm_r5fss0-0_freertos_gcc-armv7",

it seems there is some kind of bug\unexpected behavior,

Whenever i create a static global object the CTOR is not being called.

attached is the source that i used for testing (hello_world.cpp replaced hello_world.c):

hello_world.cpp

Please look into to it.
