Not getting interrupt from CPU2 to begin advertising state.

Hello,

Can you help to find the mistake. I've the same problem, but after jumping from bootloader apps to main apps.

I click "Start Debug" button in the Keil. Program is running. But CPU2 is Hardfault. In SRAM2a I see Hardfault code and another information about it (AN5289):

1) Program counter value that generate the hardfault: 0x0002607C

2) Link register...: 0x0001FE1B

3) Stack pointer....: 0x2003F1F0

But i can't find information about it anywhere.

My program start from 0x08010000 and SRAM from 0x20000004.

If Bootloader started in OTA mode - BLE is working fine.

But if Bootloader jump to the main program - BLE is not working. And if I start the debug session for main program from the Keil too. Another functions in my main program (graphics, display, interrupts...) working fine. Only CPU2 doesn't work.

All buffers for CPU2 stay in SRAM2 memory. I checked it.

Jump function in the bootloader.

static void jump_to_main_fw(void)
{
 typedef void (*fct_t)(void);
	fct_t app_reset_handler;
	
	SCB->VTOR = FLASH_ADDRESS_MAIN_PROGRAM;
	__set_MSP(*(uint32_t*)(FLASH_ADDRESS_MAIN_PROGRAM));
	app_reset_handler = (fct_t)(*(uint32_t*)(FLASH_ADDRESS_MAIN_PROGRAM + 4));
	app_reset_handler();
 
	/**
	* app_reset_handler() never returns.
	* However, if for any reason a PUSH instruction is added at the entry of JumpFwApp(),
	* we need to make sure the POP instruction is not there before app_reset_handler() is called
	* The way to ensure this is to add a dummy code after app_reset_handler() is called
	* This prevents app_reset_handler() to be the last code in the function.
	*/
	__WFI();
}

Linker file for main program:

LR_IROM1 0x08010000 0x00000FFC { ; load region size_region
 ER_IROM1_LOW 0x08010000 0x00000FFC { ; load address = execution address
 *.o (RESET, +First)
 }
 
 
 RW_IRAM1 0x20000004 0x2FFFC { ; RW data
 .ANY (+RW +ZI)
 }
 RW_RAM_SHARED 0x20030000 0x2800 { ; RW data
 *(MAPPING_TABLE)
 *(MB_MEM1)
 *(MB_MEM2)
 }
}
 
LR_IROM2 0x08010FFC 0x4 {
 ER_IROM1_MED 0x08000FFC 0x4 { ; load address = execution address
 *.o (TAG_OTA_START)
 }
 }
 
LR_IROM3 0x08011000 0xEF000 {
 ER_IROM1_HIGH 0x08011000 0xEF000 { ; load address = execution address	
	*(InRoot$$Sections)
	.ANY (+RO) 
	*.o (TAG_OTA_END)	
 }
}

Could you tell How can i check it?

Thanks
