Linux/CC2564C: Can't init device CC2564B

Part Number: CC2564C
Other Parts Discussed in Thread: CC2564

Tool/software: Linux

Hi,

I am working with a CC2564C module with the BeagleBoard Black (latest image). I have the same problem as this thread, just different chip. I know I have communication with the chip through UART since I already did the first steps of the CC256x Testing Guide and I can see the response with my logic analyzer. I got the bts file from another post in this forum for that exact version.

root@beaglebone:~# hciattach /dev/ttyO5 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.6.15.bts
Loaded BTS script version 1
texas: changing baud rate to 115200, flow control to 1
Can't init device hci0: Device or resource busy (16)Can't initialize device: Device or resource busy

Regards,

Carlos

    Hi Carlos,

    The "TIInit_6.6.15.bts" is not a valid bts file for either CC256xB (TIInit_6.7.16) or CC2564C (TIInit_6.12.26). Did you manually change this? If not, exactly where did you get the bts file from?

    What version of BlueZ are you using?

    Best regards,

    Hello Vihang,

    I got the "TIInit_6.6.15.bts" file from this post. I looked for that file since if I don't have it , that is the file it requests:

    root@beaglebone:/lib/firmware/ti-connectivity# hciattach /dev/ttyO5 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.6.15.bts
can't open firmware file: No such file or directory
Warning: cannot find BTS file: /lib/firmware/ti-connectivity/TIInit_6.6.15.bts
Can't init device hci0: Device or resource busy (16)Can't initialize device: Device or resource busy

    I am using BLueZ version 5.23, it is the stock version that came with the BeagleBone black newest image.

    Thank you very much for your time.

    Regards,

    Carlos

    Hi,

    This post is about the older CC2560A/CC2564 (NRND). Is there a reason for using the older device and not the new CC2564C?

    Hi,

    Maybe I don't have the right bts file, could you provide the right one. I am using the CC2564C. But as you can see in the output the device is for some reason requesting the TIInit_6.6.15.bts version.

    Regards,
    Carlos

    Hi Viahng,

    I consulted with the hardware team and they tell me that the development board I have has a CC2564 plain, but in the future we will migrate the platform to a CC2564C this is just what we have on hand.

    Either way, we still need to integrate this with the Beaglebone.

    Regards,
    Carlos

    Hi Carlos,

    That explains the problem you are getting. The older device may have some broken compatible with the new BlueZ version. I recommend you change it with the CC2564C and use the TIInit_6.12.26.bts found at the following link.

    git.ti.com/.../initscripts

    This will solve the problem.

    Best regards,
