I have a STM32L431 that jumps to the bootloader using a software jump to 0x1FFF0000.I verified that the PB8 and PB9 pins are used on my system and I also have a 8MHz crystal soldered. I let the bootloader run then I send a 0x79 standard identifier wi...

Hi all,I have a project with a SMT32L431. Right now it is running on the nucleo-64 demo board (its a STM32L4 33RCT6P) so nothing is connected to the board.The project will use all UART and LPUART modules, the SPI1, the I2C2 and the CAN1 module. I hav...

Hi all,I am designing an application on a STM32L431. I need to consume the least amount of power. The MCU will have to use the CAN module both in transmit and receive mode. The reference manual does not give too much details on how the lower power mo...

I get a DIV_0_TRP enabled according to SMT32CubeProgrammer. Anyone with an idea? Should be simple, I verified with logic analyser that 0x7F is sent and I verified with that I am in the 0x1FFF0000 region when pausing the device.

I wait until the Rx pin goes low (which means the bootloader is configured I think), then I send the message which is the first blue spike on the first row.Zooming in we see the error instead of the ACK If I send with no data it is the same problem ...

I set all inputs to GND and now I get 270uA before SPI init. Much better. However, after SPI, I have 413uA and after I2C I have 500uA. So I2C takes 70uA which seems like a lot and SPI takes 143uA which is too much for sure. For SPI, I set the MISO pi...
