In my program i'm doing FOTA via BLE.
I developed my code with Nucleo-l476RG EVB and Nucleo-IDB05A1,
based on the
FP-SNS-FLIGHT1 program.
Now I'm working with my custom PCB using STM32L476JEY as MCU and
BlueNRG-MS and have problem with system reset.
I can see all the packets
transferred successfully with correct CRC. I write the firmware to address 0x08040008 and add the magic number to 0x08040000. Then, when resetting with HAL_NVIC_SystemReset() function the old program is restarted.
The __ICFEDIT_intvec_start__ address was: 0x08000000, so I supposed that my program takes the bootloader place and Ichanged it to 0x08004000, also the VECT_TAB_OFFSET to 0x4000.
With these changes the reset doesn't work in any case, even before doing OTA via BLE. I can just flash my program from IAR.
I'll be happy with any ideas ,
thanks
