LAUNCHXL-CC1312R1: Off-chip OAD routine failed

Galaxy Yue

Hi Team,

I use two CC1312R1-LAUNCHXL, one for sensor and one for coprocessor.

Use the latest version of linux to do OAD,

After flashing the hex of the bim routine and the bin of the sensor_oad_offchip_secure routine to the sensor, initiate an upgrade on the Linux side (use the u command)

But on the sensor side, the failure will be displayed directly as shown:

linux:

Linux itself communicates normally.

What causes this error?

How can iIsolve it?

Thanks for your support!

B&R,

Galaxy

Hi Galaxy,

1. Can you use a packet sniffer to capture what's going over the air?

2.Are you using the SECURE predefine?

3. If you look in oad_client.c and displayOadStatusUpdate() you can see the different statuses. "Failed" is the default error so I'm not sure what causes it.

Cheers,

Hi Marie H,

Long time no see.

I want to know:

The current OAD routine is to connect the coprocessor through the Linux gateway to upgrade the sensor. So how to upgrade the sensor through the collector? Is there any relevant routine or documentation?

I have run through this sensor_oad_secure, but it is not suitable for our usage scenarios. We hope to use our own gateway,,,and use the collector and sensor architecture, without the coprocessor side.

Best Regards,

Galaxy

Hi Galaxy,

If I understand you correctly, you want the OAD distributor to be a fully embedded solution. This means you will use a serial interface to download the OAD image to the OAD Distributor, then send it over the air to the OAD target.

We don't have an example showcasing this with the TI 15.4-Stack.

We have an example showcasing this for proprietary RF (using the RF driver directly). I don't know if you would find it useful to take a look:

- OAD distributor (server) example: https://dev.ti.com/tirex/explore/node?node=A__AGwQdv9ra0XP4gK9FJZ4tg__com.ti.SIMPLELINK_CC13XX_CC26XX_SDK_PROPRF_MODULE__BSEc4rl__LATEST&placeholder=true

- OAD target (client) example: https://dev.ti.com/tirex/explore/node?node=A__ANCe4a5oZ0oou12gJ3QPgA__com.ti.SIMPLELINK_CC13XX_CC26XX_SDK_PROPRF_MODULE__BSEc4rl__LATEST&placeholder=true

- Documentation: https://dev.ti.com/tirex/explore/node?node=A__ANCe4a5oZ0oou12gJ3QPgA__com.ti.SIMPLELINK_CC13XX_CC26XX_SDK_PROPRF_MODULE__BSEc4rl__LATEST&placeholder=true

Directly using RF drivers seems to be quite complex, and there are many areas that need to be ported. If the OAD function of the coprocessor is ported to the collector, can you provide some porting assistance

Hi Marie H,

Faker Wang is the source of the problem.

Please provide some suggestions for Coprocessor migration plan.

Or,

In the Linux environment, one collector serves as the host and multiple sensor nodes to implement OAD.

Thanks for your supprot !

Hi Marie H,

Can you provide some assistance in porting the load function of the coprocessor to the collector?

Part Number: LAUNCHXL-CC1312R1

Hi guys:

I use two pieces of CC1312R1,One as a collector and the other as a sensor, Now the business has been completed.Only the load function is missing.

The load function provided in the routine is based on the coprocessor.

Can you provide some suggestions or documentation for porting load functions from coprocessors to collectors?

Hi Faker,

Unfortunately we don't have any example project or collateral to illustrate how to do this porting. We don't have the resources to help you further here.

I wish you luck, and if you run into any specific errors or questions please feel free to post in the forum!

For now I will close this thread.

Cheers,
