Problem communicating with peripherals when booting from NOR flash on C5515 ezDSP USB stick

Hi,

We've been developing a demonstrator based on the ezDSP USB C5515. It uses the built-in audio and most of the other peripherals to communcate with some external hardware.

We included PLL configuration and peripheral reset instructions based on the GEL file for the board, and verified that the code would run correctly when loaded from CCS without the GEL file.

We then flashed to NOR using the programmer from the wiki, and it would not work.  On power up, the code runs, we can talk to some but not all the peripherals, and not all the code worked making the demonstrator completely inoperable.

Although we're not using the FFT, and the board is slightly different, the symptoms were similar to those described in http://e2e.ti.com/support/dsp/tms320c5000_power-efficient_dsps/f/109/p/126035/462564.aspx

See next post, we think we have a fix.
