Ticket Name: Linux/TDA2EVM5777: How to build ELF firmware working with remoteproc using GNU tools?

Query Text:
Part Number: TDA2EVM5777 Other Parts Discussed in Thread: TDA2 Tool/software: Linux Hello *! I'm using the XC5777x Board with TDA2 Processor. Now I have to realize a baseline concept which fullfill the following requirements: A15 Core runs Linux and wil be the "Master" of the system. (This is works great!) All other cores have to be programmed "real bare metal", which means: no proprietary tools. No TI-Compiler, BIOS, RTOS... But I am not able to create any kind of working "ELF" file, which will be loaded and started successfully by remoteproc (Linux). All I got is "write error: Cannot allocate memory". This points to the kernel driver of remoteproc and crahes, if the section ".resource_table" can not be found or is empty, filled with garbish... ? But I can see such a section using "readelf"... But it do not work at all. I can put this section whereever I want... no success at all. I used some linker script and header-files from visual_sdk to generate such a section... but withous success. The linux runs well, because a "Prebuild" (!!) example, without sourcecode... works fine! (messageq_single.xem4) Do anybody ever build a firmware successfully for C66x and M4 subcore which works fine using remoteproc? Please help me out with an example of how it work. (Linker .lds file, header files, simple main.c, startup code (*.asm), Makefile... using GCC... no CCS, no SDK, please...) Thank you: Marco
