Hi,I'm using X-CUBE-AWS 2.2.0 with a B-L4S5I-IOT01A dev board. While trying to provision and save the keys, the erase function HAL_Erase_Data_Zone() is returning the error STSAFEA_KEY_BLOCKED. I have made sure that DBANK is 0. I enabled PRINTF_ON ...

FreeRTOS, debugging hardfault when HardFault_Handler breakpoint is never triggered?

I'm looking at the "Debugging and diagnosing hard faults" on FreeRTOS' website (https://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.html), and I populated my HardFault_Handler() function and defined prvGetRegistersFromStack()....

STM32F407VGT7 I use system memory boot mode by USART1 (PA10, PA9). i have to use external pull-up/pull-down resistors to USART3 (PB10 / PB11, PC10 / PC11), CAN2 (PB5), USB (PA11, PA12)?

I am using STM32H7A3 board. I am trying to integrate SD Card using SPI. I am getting FR_DISK_ERR when I try to do f_mount. Attached source code.

When i tried to give Pull ups for SPI pins except SPI1_SCK, i am getting FR_NOT_READY error.I am completely stuck in this issue. Please have a look into this and provide a solution for me.Thanks in advance.Jestina

Hi, I am using a STM32L496. On the board is a buzzer. If the buzzer works, an USB connection lost the transmit functionality. Receive is still ok. The supply voltage is stable regards Josef
