Hi
I am looking for an offical guide for implementing and testing SUOTA features of the DA14531.
I can not find a link under the offical download section of the DA14531.
我已经尝试指导从other chips but it did not work as expected and I am not sure if there are differences.
I am not sure which secondary bootload I have to use (580, 585), and if I have to create them manually with the python script or use the included pop-up dialog from the SmartSnippets Toolbox for creating a multi image.
Best regards

Currently there isn’t any available document describing the SUOTA procedure in DA14531, but we are working on that. You can follow theTutorial 6: SUOTA example for DA14585/6which is based on DA14585/586 product family. The procedure is similar in DA14531 and SDK6.0.12. To do so, I would suggest to follow the aforementioned tutorial and let me know if you need any further support on that.
Regarding the secondary bootloader, you should open the appropriate Keil project which is located under 6.0.12.1020\utilities\secondary_bootloader SDK path and build it for DA14531. Default configuration is for DA1458, so you will need to change it. After that, the binary image you should use as a secondary bootloader will be located in \secondary_bootloader\out_DA14531\Objects generated folder named secondary_bootloader_531.hex. As described in the DA14585 tutorial, you should use and python script in order to create the multi binary image. No need to create a multi imaged thought the SmartSnippets toolbox. Please select the default option which is the “Do not modify” and make sure the “Bootable” checkbox is unclicked.
Thanks, PM_Dialog
