Hi,I came across a HardFault in my code while in debug mode on STM32CubeIDE, and I checked the SFRs register viewer and noticed that I ran into a PRECISERR, and the BFAR field shows which address triggered the data bus error. I have attached a screen...

Hi Everyone,I previously made a project through STM32CubeMX based on the STM32L431CCT6 to generate the pinout and initialization template for Keil MDK-ARM IDE. We are planning on transitioning to the STM32L431CBT6 (without any changes to the code), a...

Hi,I was reading the BlueNRG-2N features on this datasheet, and it stated that it could "handle up to 8 simultaneous connections."Does this mean that one GAP Central device based on the BlueNRG-2N could transmit up to 8 GAP Peripheral devices (also c...

Hi,I picked up a X-NUCLEO-BNRG2A1 (Extension board Lot:2040 for the Nucleo-64 boards), and I am trying to communicate with it through a Nucleo-F411RE Board. I basically generated a project template through CubeMX for the STM32F411RE and included the ...

Hi,I am trying to setup the TIM1 of the STM32F410CBT microcontroller so that TIM1->CNT can measure Channel A and Channel B of a Quadrature Encoder Interface of a motor (the Encoder's datasheet is here, and it came attached with this motor here). I ha...

Thanks for sharing this with me!

I managed to print out the contents of PC, LR, PCR as you suggested, and found out that one of the variables are trying to access an invalid location. The issue came down to insufficient FreeRTOS timer task stack size when calling hci_user_evt_proc()...

I observed the contents of 0xB005_4620 on my STM32CubeIDE's Memory Window and it displayed question marks only ('?'). When you mentioned call stack, did you mean observing LR, PC, R0, ..., R13 too?

Thanks for the response! I did examine the PC and LR registers after the HardFault_Handler() got executed, and the PC pointed to the HardFault_Handler() function, while the LR register contained a value of -3 (based on the second picture posted in th...

Thanks for the response! It did not occur to me that 0xB005_4620 isn't in FLASH or SRAM. Since this is the case, why would the BFARVALID bit be set and why would BFAR point to that address? Do you also have any tips or pointers on why a PRECISERR oc...

Is it possible to check which line of code resides on a particular address on STM32CubeIDE?

Do I need to create a new project (CubeMX and Keil MDK-ARM) when migrating from STM32L431CCT6 to STM32L431CBT6?
