I am trying to flash code over CANBUS on Nucleo-F446. I am referring this application noteshttps://www.st.com/resource/en/application_note/cd00264321-can-protocol-used-in-the-stm32-bootloader-stmicroelectronics.pdfSo according to it in Boot mode the ...

@Community member Thanks. That makes sense. I am trying now with idle line detection to start and stop DMA.

I am interfacing TFmini S LIDAR with nucleo STM32F103, I am using 2 UARTS, uart1 and uart3 to receive LIDAR data. I am using DMA for that. LIDAR frequency is 1000Hz and data length is 9 bytes. uart 1 and 3 baudrate is set to 256000.

Unable to get bootloader access over CANBUS. No response from STM32 over CANBUS.
