Problem calibrating MSI clock using LSE
Hello, I've been trying to calibrate the system clock of a Nucleo-64 board (STM32l152) using approach proposed in AN3300 to compensate the temperature error. The proposed solution works fine with HSI clock running at 32MHz. At room temperature the op...
Bluepill to STM32F446 with CAN Bus
Hi. I have developed a CAN based protocol to a Bluepill and now I need to test that on the Nucleo board as well. I have been trying this for a while now and for some reason CAN messages are generated from the Nucleo board. The code was working fine w...

Resolved! FLASH_PageErase() works but HAL_FLASHEx_Erase() does not
SOLVED: I didn't convert the flashErase_handle.PageAddress to hex, so I was passing in the integer 800_8000, which is much less than 0x800_8000I'm using the Nucleo F303RE board and as part of a bootloader trying to erase pages of flash containing th...
