The keys are different, header the same, but e.g lengh of words in key35 is 11 on wt32, on cst i have only 5 words.

I tryed setup leds using rom conf. on wt32, this not work too.
I thing the interpreter of words is different in thes modules.

Would guess this is due to the different Bluecore version. The WT32(i) is a BC05-MM module.

So when setting up the CSR8645 to PCM or I2S or any other digital output, clock generation must work (when set as Master), even if the digital audio stream is not connected to the output pin.

From "CSR8645B04 Issue 9" History:

Clarification that IS is implemented as HCI only.

So you where right, I2S is only working when having USB streaming enabled. Put PCM should work anyway.

This where different in "Issue 6".

For PCM you'll have to deal with:

PSKEY_PCM_CLOCK_RATE
PSKEY_PCM_SLOTS_PER_FRAME
PSKEY_PCM_SYNC_RATE
PSKEY_PCM_USE_LOW_JITTER_MODE
PSKEY_PCM_CONFIG32
PSKEY_PCM0_ATTENUATION

Then you maybe need to choose the SCO you want to stream out. Getting the right parameters for PSKEY_PCM_CONFIG32 will need some more research, there's some help here:

At 10.3.10.

Testing the PCM can be done by a BCCMD like "PCM_Ext_LB", there's a list called "Bluecore BCCMD Commands".

I had these CSR8645 modules running as USB-Audio-Soundcard some month ago.

BCCMD commands should work with the debugger included in the ADK via SPI as well.

Flashing with "Headset Configuration Tool" directly might brick your module. When it is not responding anymore check current consumption. Bootloop behaviour can easily be seen by jumping current at startup.

I use PSTOOL via LPT SPI.

If you have no LPT, I had success with UM232H and UART.

Take a look for PCMConfigV2.xls, thats an excel spreadsheet to generate the hex code.
If you can't find it, write me a mail.
