SUOTA Failing

Hi Flaby,

Thanks for your question online.

Firstly, I would recommend using the latest SST which is version 5.0.14. If you are using a previous version, please update it with the last one.

This error means that something went wrong with the multi-image generation and the product header is invalid.

My suggestion would be to follow the tutorial in a clean SDK directory using the pxp_reporter examples of the SDK.

However, the tutorial is missing a step - we are working on that. You will need to modify the sdk_version.h file and have 2 different files : fw_1_version.h and fw_2_version.h

When creating the single image – “make single image” – figure 7, you first need to check that the sdk_version.h file is up to date. The sdk_version.h can be found under the following path:

C：\程序文件（x86）\ smartsnippetstoolbox \ smartsnippetstoolbox5.0.14 \ common_resources \ supportpackages \ da1453x \ toolbox_resources \ common \ sdk_version.h

When creating the second .img file - “make single image” , the sdk_version.h file should be modified again in the same location, in order to have a newer revision number.

Once the multi-image is generated, bunt the flash without making the device bootable. When the Flash is burnt, verify that the product header is at address 0x38000.

Please let me know with the results!

Hi flaby,

Thanks for the attached files.

The multi-image seems to be generated properly :

0x00000 à bootloader ( starts with 70 50 )

0x04000 à 1^st图像（以70 51开始）

0x1F000 à 2^st图像（以70 51开始）

0x38000à产品标题（以70 52开始）

Question : what is the value of the PRODUCT_HEADER_POSITION in the 6.0.14.1114\utilities\secondary_bootloader and 6.0.14.1114\projects\target_apps\ble_examples\prox_reporter projects? Can you please verify that both have been built with the PRODUCT_HEADER_POSITION configured to 0x38000.

Thanks, PM_Dialog

Hi Flaby,

Unfortunately, I am not able to replicate this. I have tested this in my side and I am able to perform SUOTA. Please check the .hex and .img files that I am using.

Important : when generating every single image, in the 2^nd步骤SS Toolbox将要求您选择SDK标题文件（请参阅（SDK_VERSION）。

In case of fw_1.img, in the first step you should select the fw_1.h ( figure 7 ) and the sdk_version_1.h in step 2 ( figure 8 ).

In case of fw_2.img, in the first step you should select the fw_2.h ( figure 7 ) and the sdk_version_2.h in step 2 ( figure 8 )

This step is missing in figure 8. See attached.

The sdk_version_1.h and sdk_version_2.h should contain different sdk information. Otherwise, you will get a “same image” error.
