Other Parts Discussed in Thread: TMS320F28335
hi,
i'm working at porting a non-DSP/BIOS application to DSP/BIOS using CCS3.3 and DSP/BIOS 5.41.10.36 on a TMS320F28335 and I have stumbled across a problem with the chip appearing to be permanently locked.
i downloaded spra958i and started with the flash based example, which worked.
without power cycling the board i added a task to print some data to the trace output and flashed it on, it worked great. I then added a little more code (like 'hello world' type of tests) and flashed it, again this worked fine.
Then I power cycled the board and now CCS tells me 'ADC Calibration not complete, check if device is unlocked and recalibrate.'
i tried another setup and it too has been locked, the lock only seems to become evident when the board is power cycled
Can anyone help? is the board really locked?
