OTA Reset Manager is not jumping to user application
Hi
I'm trying to enable OTA Service on my device with the BlueNRG2 Chip.
I use the Lower Application Scheme. Therefore I flash the BLE_OTA_ResetManager at the flash beginn at 0x10040000. (I did a mass erase before that). I didn't modify the OTA ResetManager application, I took it from the BlueNrg-1.2 DK 3.2.1 example project.
Then I flash the user application with enabled OTA service at 0x10040800 as described in the documentation. I tried it also with the given example projects BLE_Chat or BLE_Beacon, but the Reset manager is never jumping to the application.
I can see that the reset manager reads correctly the AA5555AA tag at the correct location and get therefore the correct application to jump. But after the Jump_to_Application() call, it seems that it falls into a hard fault and makes then reset. And this will then happen in an endloos loop.
Do I missunderstand something or what is wrong with my code/approach?
Many thanks for every hint!
Code of the main function of the OTA_Reset_manager:
int main(void)
{
pFunction Jump_To_Application;
uint32_t JumpAddress, appAddress;
/* Identifies the valid application where to jump based on the OTA application validity tags values placed on
reserved vector table entry: OTA_TAG_VECTOR_TABLE_ENTRY_INDEX */
appAddress = OTA_Check_Application_Tags_Value();
if (appAddress == 0) {
/* This case indicates that no valida application is present and normally should not happen */
while (1);
}
/* Jump to user application */
JumpAddress = *(__IO uint32_t*) (appAddress + 4);
Jump_To_Application = (pFunction) JumpAddress;
/* Initialize user application's Stack Pointer */
__set_MSP(*(__IO uint32_t*) appAddress);
Jump_To_Application();
/* Infinite loop */
while (1)
{
}
}Many thanks.
