I'm using the latest version of Processor-SDK RTOS on a BBB(AM3358)
I created a new Sys/Bios project with "Minimal" setup in CCS. I have a test main.c to toggle an LED. I copied the source from GPIO_LEDBlink_bbbAM335x_armExampleProject. My generated configPkg/linker.cmd file is attached.
However, when I goto compile the project, I get undefined symbols. How does the project know which lib file to include? Is it in the platform file?
