DSP56858EVM - Can't get SPI boot to work.
Hello all, I am trying to execute the Second Stage SPI Bootloader Demo in the SDK using a DSP56858EVM board. Everything seems to work except booting. Serial_flash_prog.mcp executes without a problem. The dialog with the EVM via Hyperterminal is posted below. I do notice that the program sizes don't match the documentation exactly but neither does the Version number for the Serial Data Flash Programmer. After completing the Serial Data Flash Programmer, I kill the debugger session and disconnect the JTAG Connector ($25 from NMI works great). I then kill power, set MODA switch to off and then re-apply power. All LEDs light up but no flashing. Executing Timers.mcp via JTAG works as expected. I have monitored the SPI bus and the serial Flash part does reply with BOOT (42H,4FH,4FH,54H) in the first four bytes. The next few bytes look correct also. I am loading ….nos\applications\bsp\timers\Debug\InternalRAM.elf.S as the application
S-record below.

Hi, in general you should be able to connect via JTAG to running target (after your re-applying of power) and break to debuger. Then you should see where the code is running if it's running at all. It might give you an insight what is happening.

After further testing I believe that my problem is with the 2nd Stage
Bootloader.
After programming the 2nd Stage Bootloader and the Timers demo into the
serial flash, I can reboot in Mode 1 and see BOOT being clocked in via the SPI
port. The Timers demo never executes that I can tell. If I execute
the 2nd Stage Bootloader via CodeWarrir and the JTAG port though, it will load
and execute the Timers demo (or anything else that I program into the serial
flash).
Is anyone using the 2nd Stage Bootloader in the SDK? Are any
changes required to make it work from the serial flash?
For Jan:
I am new to these tools. How do I break into a running target and
see where the code is running? Can CodeWarrior do
this?
Thanks,
Louis

Problem solved! The original EVM that I have has an old DSP on
it. There was a problem in the silicon that has since been
corrected.
Moral of the story: Read the errata when you are having
problems!
