CC256x on PAN1323 module SP download issue

Philippe Dedieu

Other Parts Discussed in Thread: CC2564

Dear,

I'm working on implementation of PAN1323 module on custom board. For evaluation, I use PAN1323ETU module connected directly to my PC throught FTDI FT232R USB-to-UART converter.

I setup RX/TX RTS/CTS crossing lines in accordance with CC256x datasheet and use external 32.768kHz oscillator to provide clock required by CC256x chipset. All my signals are drived at 3v3 voltage.

When I powered the PAN1323 module, I see HCI_RTS goes LOW. The module seems to be ready.

I checked 32.768kHz clock (after level shifter) : I have 32.768kHz at 0.1% precision.

After this, I tried to launch btool, and get a response of the module (but with timeout after) : Refer to log below

The module answered to btool request. By consequence, UART lines are working properly.

I red Service Pack (SP) needs to be downloaded to initialize CC256x chipset. I get some *.bts file but I'm unable to download them on the target by any way (CC256x Bluetooth Hardware Evaluation Tool; teraterm)

Do you know the right way to download SP and the right SP to use ?

Thanks.

Hi,

The right service pack to use can be found here(CC2564 for PAN1323): http://processors.wiki.ti.com/index.php/CC256x_Downloads

Using the Bluetooth Hardware Evaluation Tool you should be able to do it. see: http://processors.wiki.ti.com/index.php/CC256x_Bluetooth_Hardware_Evaluation_Tool#Setup.C2.A0Configuration

Hi,

Thanks for the links. Unfortunetely, I already try with theses bts files and bluetooth evaluation tool but all iterations were unsuccesfull. I'm always in timeout situation.

I checked timing of UART signals and measure a 800ns rise time on HCI_CTS line between level shifter and CC256x. Do you think it could be a cause of the communication issue ? Others lines rise/fall time are equals or less than 10ns.

Regards.

Hi Philippe,

Yes, It could be the problem. Anyway I am checking it internally with the hardware team, I will get back to you on this.

Hi Philippe,

Since HCI RTS is going low, I assume the device is power up correctly. It seems more of a UART communication issue. Could you check if VIO is 1.8V and baud rate is 115200bps?
Also, please note that btool is not for CC256x, You need to use BHET to download firmware to CC256x

Regards,
Gigi Joseph.

Dear,

Yes, VIO is 1.8V and baudrate is 115200bds.

I already use BHET to try to download firmware, but I have always timeout error or bad answer in some cases.

Regards,

Philippe

Hi Philippe,

And how about the Transparent Code?

Have you also ported the transparent code (http://processors.wiki.ti.com/index.php/CC256x_Bluetooth_Hardware_Evaluation_Tool#Example_A:_Transparent_Mode) to your custom platform to enable it to work with the BHET?

Regards,
Gigi Joseph.

Dear,

I'm not ported any code due to the usage of my PC in first step to drive the module. I just placed FT232R beetween PC and BT module to get right voltage level on PAN1323ETU module.

Regards,

Philippe

Hi Philippe,

Can you paste a screen shot of the UART TX and UART RX line for the first command/event, please?

Gigi Joseph.
