I'm having trouble getting a second batch of DM6467T boards to run. I've had to give up my prior "golden" board, so I'm comparing behavior with the DM6467T EVM (aka Spectrum Digital HD1080P EVM).
When I load the program nand_flash_writer.out on the EVM, I can run it and it prints out some stuff to the CCSV4 console window. I don't go any further than that because I don't want to ruin my EVM.
When I try to do the same thing on my own board, aside from other issues, I can get to the point where I run the program. But no output appears on the CCSV4 console window.
On the EVM, I've even gone so far as to single step through the nand_flash_writer assembly code (don't have source). I find that it goes through functions named main, test_execute, printf, _printfi, and fputs. It's a lot of code, so I skipped around a bit. Somewhere between fputs and the end of _printfi, the actual text comes out the console window.
On my board, I've tried the same. Early on, I let the program run to totally through the test_execute function. While the EVM prints to the console, my board does not. However, my board DOES come back to the same instruction as the EVM! This implies the proc on my board is running correctly, but that somehow it's output isn't showing up on the CCSV4 console window.
This begs the question, WHAT IS THE CONSOLE WINDOW? In other words, what physical representation on the proc is receiving text from the program, such that this text is, I assume, intercepted by CCSV4 and displayed on the console window? If I knew the answer to this, I might be able to do a little debugging on my own board to figure out why that part doesn't work.
IN ADDITION, it sure would be nice to have source code to nand_flash_writer.out. Does anyone know where I can get source code to match my .out? (I'd rather not change .out's just yet, as stirring in additional variables might further confuse my progress.)
Finally, do note that I'm having other issues. After a few minutes, my board won't get as far as it did before, After a few more minutes, my board responds differently to the "Load Program". It seems to load it. However, while the EVM will load the program and then be in the "Suspended" state, my board will load the program and then be in the "Running" state. What's up with that? It seems something is wrong with my board, but I have no clue what it is...
Thanks,
