Some information from LiquidSilver:

The CPLD is accessed at virtual addres 0xbd000000

 
This is turning bluetooth on:

0xbd000002 is the CPLD group B register -bits 0-2 are the led control bit bit 3 is the bluetooth 32k clock. 
0xbd000004 is the CPLD group C register bit 0 is the bluetooth enable 
0xbd000000 is a virtual address the real address is 0x98000000 
0xbd00000c bit 0 is a charging bit I think. 
 
I think on Nike only the first 4 bits of each CPLD group are really used. 
 
Haret incorrectly reports the GPIO pin numbers for example 
010.296 GPIOS out3: out3-8(104)=1 
010.296 GPIOS in3: in3-8(264)=1 
 
are the same pin. Haret thinks every bit from the base of an address is a GPIO pin. Thus out3-8 is (3*32)* 8 = 104. 
 This is not the mapping but you can find the mapping in GPIO.c in the android source. For the record out3-8 is GPIO pin 76. 
 
Haret GPIO tracing is only tracing the MSM7200 GPIOs. The CPLD GPIOs have to be traced by watching accesses to address 0xbd000000 - 0xbd000014. 
Android labels the first CPLD GPIO as GPIO 128. The cpld GPIO numbers are linearly mapped to the bits in the address. Thus 0xbd000002 is GPIO 136. 
 
The haret documentation details how to get haret running and make traces. 
I used the package in the obtaining haretconsole section http://www.handhelds.org/moin/moin.c...0Documentationto connect to haret.
