want make stand - alone a TMS320C6711

Started by ulis...@inwind.it December 5, 2005
Hi,
I would want make stand - alone a TMS320C6711, to such purpose, I have modified the post and recharge it in the dsp. If I do to function the dsp in "run - free" mode, that I set with Code Composer Studio, it executes the post all times I reset it through the reset button on the dsk board, but if I remove and reapply power at it, the post isn't executed at the boot. I would like to know the cause and, as to perform the post to the start.
Must I change the boot configuration through pull - up and pull - down resistors? In such case, since there aren't special jumpers on the dsk board, how do I perform this operation?
If I accept that it is always in power, how can I set the "run - free" mode by hardware rather than software?
Thanks in advance,
Thomas



Hello Thomas,

The DSK is set up for Flash boot by default. If you
take a new DSK and apply power or hit reset, it will
run through the test process and blink the LEDs.

'Run Free' in CCS is >99% the same as the board
running stand-alone. Your problem/difference is most
likely due to something that CCS is initializing for
you. Try bringing up CCS without a GEL file and doing
'run free' and see if that works. If it fails as I
suspect, look at the GEL file to see what is being
initialized. You may want to make a copy of it and
edit it to remove initialization 'one-by-one' to find
the culprit.

Also, make sure that any code that accesses the LEDs
is executed from RAM.
