SBSFU Rollback with stm32L476RG

[Kurien_Raju]

Hi All,

I am following the UM2262 document. I will add a screenshot. I enabled the ENABLE_IMAGE_STATE_HANDLING flag to enable rollback, but after updating UserApp.bin, the device continues to reset. I will add a debug log screenshot (it’s not jumping into the application). Please help me with any references for the rollback feature using the SBSFU package version 2.6.x.

Hello @Kurien_Raju ,

as far as I remember, you need to add this flag to all projects (SBSFU, SECoreBin, appli), and perform a clean build for each one to make this work.

Is this what you have done ?

Best regards
