Keep security credentials/WiFI config in DCT during JTAG flashing

[EyLa_3227556]

Hi,

While developing I get to the point where a wiced device does \provision by claim' with the AWS cloud in which it gets the required credentials (certificate + key pair).

These are stored to the DCT_SECURITY_SECTION in the DCT.

Now,during development when JTAG flashing new version to the platform, the credentials are overwritten and have the provisioning has to start all over again.

What is the correct way to download new app to the platform while retaining the security credentials?

Same question apllies also to DCT_WIFI_CONFIG_SECTION section

Thanks

Hello,

Can you provide the make target that you are using to download the new app to the platform via JTAG?

Also, what is the platform that is being used here? Which version of WICED STUDIO are you using?

Thanks

Hi,

The platform is based on LAIRD_EWB (STM32F412 + CY4343W), Wiced SDK is 6.4

The make target used is "<Project.Folder.Path>-<PlatfomName>-ThreadX-NetX-SDIO JTAG=Olimex_ARM-USB-TINY-H download run"

Thanks
