Richard,
As long as you have set your SDR and GPMC timings correctly you can load into DDR to start your work. Do know that the code will skip Clock and DDR init then.
Yes. I gone through the code of s_init(...) and if(!sdram)..stuff !!!.
Generally, I and have the gel file do nothing, and load directly into SRAM for initial debugging. Then try it from SDRAM, then finally from flash. I've had good success stepping everything with a Lauterbach emulator.
I need to acquire the Lauterbach soon then :-).
If it crashed with 0x4020FFFC, I'd say you are using an OLD version of CCS which for some unknown reason needed a different driver to access SRAM. Other emulators I've used didn't have this issue, but I did hear that some version of CCS did.
Right now I am using 2.30.01 + patch for 24xx, with xds560 jtag driver supplied with the CCS.
So update your CCS. Or ask them for the magic driver which allows you to access SRAM.
Sure. I will check up and come back with more debug test outputs.
You will likely have some crashes due to needed changes in the code, but this is not one of them. It is likely a tool issue.
Yes. I think it is time to update the tools.
