Tool/software: TI-RTOS
Hi there,
We are working on transitioning from demo software on the EVMK2H evaluation module to a production 66AK2H12 chip. So far we have been putting software on our DSP chips on the EVMK2H by first loading the correct GEL file onto the selected DSP core via Code Composer Studio, and then loading a .out file onto that DSP core. We are running SYS/BIOS on all DSP cores.
We need to transition away from Code Composer Studio so that when we finally manufacture a prototype board with the 66AK2H12 chip we are ready to go. Currently, we want to start by switching to having the system pull the .out image for each DSP core from an SD card and then loading it onto each DSP core. This leads to some questions:
- How do pull the .out image from an SD card properly, and load it onto a DSP core? Do we use the secondary bootloader? If so, how do we do this and how do we prepare the SD card.
- How do we initialize the DSP core (PLL, clocks, DDR3, etc) without a GEL file? I see that the GEL file is written in syntax that looks like C, is there a place that we can find "initialization" code that we can run on startup that mimics the functionality of the GEL files?
- How can we see what hardware changes to expect when we transition from the EVMK2H to the 66AK2H12 chip? Obviously our memory regions will change, is there a document that details any other changes and what the transition process looks like?
Thanks!
Andre
