Bluetopia stack on Tiva c TM4C123HJ6PM

Other Parts Discussed in Thread: CC2564, CC256XEM-RD

Hi


I'm trying to use the bluetopia stack in tiva c launchpad (TM4C123HJ6PM microcontroller)

with  the CC2564 Bluetooth controller using the CC256x Bluetooth® evaluation module reference design

http://www.ti.com/tool/cc256xem-rd?keyMatch=cc256x&tisearch=Search-EN

but I'm getting always this error with the examples, I tried with SSPDEmo and HIDDemo

I'm getting this error message in serial terminal:

OpenStack().
Stack Initialization Failed: -4.
Unable to open the stack.

I added the CC2564 patch as is indicated here  http://processors.wiki.ti.com/index.php/CC256x_MSP430_Bluetopia_Basic_Demo_APPS#CC256XB_Information

and also I did a lots of checks in my hardware connection.

the Tiva C Board is sending the first packet but the bluetooth module doesn´t answer

I'm stuck

Could someone suggest me how proceed?
