Other Parts Discussed in Thread: AM6548
I am trying to run FreeRTOS which comes with the pdk_am65xx_08_02_00_21 on the R5F processor of the AM6548 on the TMDX654IKEVM board.
I can build the application, however it will not load on the R5 and run into an issue. I figured this is because of the plenty of linker warnings I get.
The linker warnings look like this:
#99922 C:/ti/pdk_am65xx_08_02_00_21/packages/ti/osal/lib/freertos/am65xx/r5f/release/ti.osal.aer5f<Arch_util.oer5f>: Invalid meta-info kind encountered in symbol metadata section (.symtab_meta)
This is not only with this library, but with many other libraries. This is the full error message:

I used the linker file which came with the PDK (<pdk-install-path>\packages\ti\build\am65xx\linker_r5_freertos.lds).
The tutorials on how to run everything and especially the RTOS did not work, because the driver need to be built by some weird XDC tools or something. That won't work because of reasons I don't know, and thus I try to make a barebone minimal FreeRTOS example.
In general I would also like to complain that the support for this product (AM6548, PDK) is very bad and it seems to be in a semi-stable, not fully functional state when downloading. Many tutorials fail to deliver basic information and it is in general a pain to navigate through everything. Also, I was often referred to the AM64xx, which is not even available yet (pre production!?!) and also is not automotive certified, which my processor needs to be. I am very dissappointed in TI products and would probably not use them again, if I wouldn't be stuck with them in this project. Also, there is no info on the error #99922 at all. In general, the documentation lacks a lot.
Anyways, I hope I can get a bit help here. Thank you very much in advance.
