Hello Community,
I am working with Quadros OS project in which I need to port PRU firmware(icss_dualmac).
What are the OS dependent component of PRU ?
What is linker command file ?
what is PRU releation with config_am335x_a8.bld ?
Regards,
Pankaj
Pankaj,
PRU firmware is not dependent on OS. Only the PRU driver to load/run PRU binary is OS dependent (supporting bare-metal as well).
The linker command file for PRU firmware is pru.cmd in drv\icss_emac\firmware\icss_dualemac\src. The PRUx_REVx_to_ARM(C66).cmd under firmware/cmd is for converting .out file to .bin using hexpru, see the attached log

The lnk_a8_a9_a15_REVx.cmd is the linker file for building ICSS_EMAC driver example project.
The config_am335x_a8.bld file defines a few memory sections that are not in default platform/board configuration file, e.g. ti.platforms.evmAM335X, but these sections are referred in lnk_a8_a9_a15_REVx.cmd. More infor on .bld file - https://processors.wiki.ti.com/index.php/Config_bld_basics

Hi Garrett,
Thanks for the answer.
In my ccs project i dont have xdc tool is in used, I am using AM335x.lds file.
Is it possible to put PRU linker command in AM335x.lds file, I have already done it but dont know it will work or not ?

Hi Pankaj,
Yes, this should work too. The linker command file is OS/XDC independent
