LAUNCHXL-CC1310: Out of flash memory, wireless connection (CC3220SF + CC1310)

Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: CC3220SF, CC1310, CC1350

Hello,

I have built a gateway using CC1310 Launchpad + ENC28J60 Ethernet Controller and ran 6LBR Lite on it because I want to establish a 6LoWPAN communication between the gateway that I built and another 2 applications (2x CC1310 Launchpads), where I ran the CC26xx web demo on them. I also want to establish wireless communication between the gateway and a CC3220SF Launchpad.

The issues I have faced are:

I ran out of flash memory for all the CC1310 Launchpads, since the 6LBR Lite is 128KB in size, and the web demo is 128KB in size as well, which is the total flash memory size for the CC1310 Launchpad.
I couldn't find any documentation on how to establish wireless communication between the CC1310 Launchpad and the CC3220SF Launchpad.

My questions are:

How can I run a code on the CC1310 if it's out of flash memory? Can I add any external component to fix that issue?
Is there any documentation to help with the communication between the CC1310 and CC3220SF Launchpads?

Thank you,

Hello Mohamed,

The resulting .bin file is always 128kB, it fills up the unused flash as well. You can add up the sizes of .text .cinit .const memory sections in the map file to know exact amount of flash it consumes.

Please refer to these posts for more information

e2e.ti.com/.../2075162

Note that CC3220 is a Wifi solution and CC1310 is a Sub 1 Ghz solution and they cannot communicate wirelessly as they do not share the same bands or protocols.

Regards,

Hello Mohammed,

1. You cannot run application code if you run out of flash memory, you can run one of the two stacks but not both, you can give this a try (dev.ti.com/.../bim.html ) this will allow you to store one of the stacks off chip and switch between two images in real time. Note that there is a limit to the number times you can write to flash.

2. we do not supply any documentation on how to communicate to the CC3220SF other than serial communication, since both devices use different RF bands. If you wish to use the Ethernet Controller to communicate between our two devices check the documentation on the ethernet controller's website

I hope this helps,
AB

Thank you!

Can I use UART to communicate between the CC1310 and CC3220SF Launchpads?

I tried running the uartechodma example on the CC3220SF Launchpad, but I got "Echoing characters" on tera term terminal. How can I receive back the echoed character?

Have you done www.ti.com/.../TIDC-01002 step by step?

No I haven't. In my design, the gateway is CC1310, but in the example the (CC3220SF + CC1310) is the gateway. Also, the gateway in the example communicates with the CC1310 in sub-1GHz, while the requirement in my design is Wifi.

- Would it be any different if the gateway I built was using CC1350 instead of CC1310?
- Do you think it's possible for me to add an extra component that would allow Wifi communication between the gateway I built and CC3220SF?

Thank you for your patience,

1. Basically, Sub GHz part of CC1350 and CC1310 are the same.
2. What’s the gateway you refer to in your question now?

No difference for CC1310 vs CC1350.

As I commented in a separate post your requirements make it more difficult to implement since in most practical systems it makes more sense to connect CC1310 with CC3220 via UART and get directly to the cloud. If you want to go via ethernet it's not longer related to CC1310 or this forum since what you need then is a thing going from ethernet to WiFi (router etc)

Thank you for your answer!

The gateway I'm referring to is made of (CC1310 launchpad + Ethernet controller), I also ran 6LBR Lite on the CC1310 launchpad to provide 6lowpan communication.

Do you think it's possible if I add an external component to that so that it allows me to communicate with the CC3220SF launchpad in wifi?

Hello,
What do you mean by " there is a limit to the number times you can write to "?

Flash degrade with the number of write cycles due to the way flash works. Check en.wikipedia.org/.../Flash_memory as one source.
