Contiki porting on to phyNODE CC2650

Other Parts Discussed in Thread: CC2650

Hi there

Porting contiki on phyNODE CC2650 isnt working well. I have done pin muxing for uart lines and 2 of the LEDS and also 1 switch.

When I compile and run contiki-cc26xx-beta150122/examples/cc26xx/cc26xx-web-demo , I get the following issues:
1. In the old rev silicon I find the board resetting every 2 seconds.

2. I also have a new rev silicon(cc2650) in which, after a main init logs it stops printing anymore data in uart, sometimes it puts series of garbage data.

Even for the contiki-cc26xx-beta150122/examples/cc26xx, I get the similar issues

Can anybody suggest me the possiblities for the above events. I am open for suggestions. Thankx in advance.

I'm trying to think out loud here:

From contiki-platform point of view it should be something like srf-26xx platform (or a sensortag flavor),
with a slightly different pinout?
From serial port point of view it should be a as if you connected cc2560EM to smartRF06EB that is running
contiki compiled for either cc2560EM, or a sensortag?

If you have CC2650EM, I would suggest you to run the same binary on it and check if it works.

Dear Igor

thanks for a swift reply. I complied for sensortag. and pin muxxed for uart and getting logs.

Dear YiKai Chen

Yes, I have a EM Card and also cc2650 sensortag. The code works just fine in both when compiled for respective boards.

Great, though it was Yikai who suggested it.
Now, what is the compilation platform for the binaries you have programmed on phyNODE CC2650?
Is it srf-26xx, or a sensorTag?

its BOARD=sensortag while building...

try with srf-26xx, I mean for the smartRF06EB with cc2560ED.

Dear Igor
I dont think I got the CC2560ED hardware..
All I have is Sensortag 2.0, CC2650EM(probably old silicon), phyNODE CC2650(new & old silicon), XDS100v3 debugger
note: I am using contiki-cc26xx-beta150122 version of the contiki
If at all I can compile for CC2560ED, how would I do that?

I didn't explain myself properly.
What I want you you to do is to compile cc26xx-web-demo project for SRF-26xx paltform, not sensortag.
I think that in this way you should be getting a more stable functionality.

By the way, is there something special about contiki-cc26xx-beta150122 branch?

The code complied for srf06 is working with my board flawlessly. But It lacks an i2c interface which I need to use for my sensors. I'm trying to implement the I2C functionality in the srf06 code already. But whenever I call i2c read/write api, I get the master busy error.

0 Igor Sherer over 8 years ago in reply to vik

Guru 31280 points

So, i'm guessing the I2C is implemented in sensortag platform?
If so, may be it's better to port it from sensorTag platform rather than implementing from scratch?

according to this site www.prlog.org/12513584-phytec-launches-new-iot-enablement-kitfeaturing-texas-instruments-cc2650.html

1. phyNode eval board which includes phyWAVE - CC2650 & multiple sensors runs one of the RTOS (TI-RTOS / Contiki ) having BLE/6LoWPAN stack can send the data to phyGATE or any BLE enabled Mobile Device.

Why are you doing porting contiki if it is done already?

Finding out and fixing the reset/hang bug in sensortag code or implementing i2c functionality in srf code of contiki, either of them will do for me. Just that I found the bus driver straight forward to understand than to pinpoint the hang issue in the sensortag code.

The TI-RTOS with BLE radio works well in the phyNODE. The contiki development is still in progress is what I found out. In contiki the 6loWPAN radio is working well and I am able to send hard code values over 6loWPAN.

so, do you have any progress with I2C?

Hi,

The web-demo (and all other demos) in cc26xx, is building differently for different BOARDS. Your issue is most probably that the sensors on the sensortag are not present on your phyNODE. I would simply create my own BOARD, based on the srf06-cc26xx BOARD, and then add, step by step, support for the peripherals you need.

Sorry for the delayed response. The Contiki sensortag code is working fine if the I2C interface1 is disabled in the code(I just skipped the init of the sensors on the I2C interface1). I am now able to talk to all the sensors on the I2C interface0. Thanks all :)
