Hi,

I have a question about PDU size.

The SDK used is the simplelink_cc13x2_26x2_sdk_5_20_00_52.

And Off-Chip OAD is used.

When PDU size is increased, application works well.

However, OAD doesn't work and download is failed.

Is there anything I need to configure to increase the PDU size in OAD and application?

Hi,

I have assigned an expert to comment on this. In the meantime, can you specify which application you are seeing this behavior in? Is this occurring on the simple_peripheral OAD example?

Best Regards,

Hi,

You may want to review the user's guide, and more specifically the section dedicated to the OAD block size.

If it does not help, please specify the following:

- is the issue reproducible with the newest SDK version (6.20)

- specify the MTU / PDU size selected in each case.

- try to identify the moment the issue is raised (is it at the end of the download, at image integrity check, etc.). I guess you could leverage the debugging guide to check on this.

I hope this will help,

Best regards,
