BOOST-CC2564MODA: Can't init device with Ubuntu 20.04

Aravinth Raj

Part Number: BOOST-CC2564MODA
Other Parts Discussed in Thread: CC2564C

Hi,

We are working on validating the HCI UART funtionality with BOOST-CC2564MODA Evaluation Board by using Linux as Host. We are able to attach the Module with Linux using btattach command, but while trying to make hci0 node up we get Device or Resource error. Please find the logs attached.

Command used to attach

sudo btattach -B /dev/ttyUSB0

Logs when attaching the Module

Bring up the module

$ sudo hciconfig hci0 up
Can't init device hci0: Device or resource busy (16)

dmesg when device or resource busy error occurs

[ 4227.635449] debugfs: File 'dut_mode' in directory 'hci0' already present!

1. Could you please point us on where we went wrong ?

2. In some forums we found that a different firmware has to be replaced into /lib/firmware/ti-connectivity/ folder, If so could you instruct How to proceed further ?

Can, you try with 'hciattach' utility?

#hciattach /dev/ttyUSB0 texas 115200

thanks

Please, try with the service packs from:

git.ti.com/.../initscripts

Thanks

Hi Hari,

Thanks for the response.

I tried using the initscripts from the source shared by you.

I copied TIInit_6.7.16.bts file to /lib/firmware/ti-connectivity

$ sudo hciattach /dev/ttyUSB3 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.7.16.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Cannot send hci command to socket: Connection timed out
Can't initialize device: Connection timed out

Then I tried a solution from https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/bluetooth-forum/738769/linux-boost-cc2564moda-cc256xb-service-pack-load-fail forum as follows,

Copied initscripts-TIInit_6.7.16_bt_spec_4.1.bts file into /lib/firmware/ti-connectivity/ and renamed as TIInit_6.7.16.bts

The Output is

$ sudo hciattach /dev/ttyUSB2 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.7.16.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

Now I copy initscripts-TIInit_6.7.16_ble_add-on.bts file into /lib/firmware/ti-connectivity/ and renamed as TIInit_6.7.42.bts

$ sudo hciattach /dev/ttyUSB2 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.7.42.bts
Loaded BTS script version 1
Device setup complete

hciattach is succesful

But only lescan is happening and I am not able to connect with any bluetooth devices.

Could you instruct on how to proceed further ?

I see.. It seems the BLE patch is not inluded in the main BTS file.

Can, you please try with the BTS file under BluetopiaPM_Linux from the service pack:

https://www.ti.com/tool/CC256XB-BT-SP

Thanks

Hii Hari,

I tried your suggestion, but the following error occurs

$ sudo hciattach /dev/ttyUSB0 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.7.16.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Cannot send hci command to socket: Connection timed out
Can't initialize device: Connection timed out

Also tried with 3000000 baud rate, yet the same result occurs.

Hi Hari,

I was curious if you have any updates on this.

Hi Aravinth,

I am also seeing similar issue with CC2564C. However, i do not see the issue with WL18xx BT controller. I wonder, if there are any endian issues. Can, you try the same experiment with a ARM host i.e AM335/AM43x/AM57x hosts?

Thanks
