Hi,I am running into a problem where the VL53L0x will return "0" for its SignalRateRtnMegaCps value for certain range measurements. Some sensors I have it does this an overwhelming amount of the time. Some sensors I only see this periodically.I use t...

Hello all,I am flashing some STF091 chips with STM32CubeProgrammer and discovered "Automatic Mode" which looks perfect for flashing many chips in a small amount of time.After I flash a chip, I am setting the option bytes so that the chip will boot in...

Hi,I have been reading through documentation for the ST UART bootloader on the STM32F091cc chip. I want to use UART2 as my UART for both standard serial communication and FW updates.UART2 can use pins (PA2,PA3) or (PA14, PA15). I would like to be abl...

Hi there,I currently have a system where I am using a UART Rx/Tx in "interrupt mode". Right now I am receiving packets of indeterminant length so I have a "header" section that contains the size of the "body section".Basically my code bounces back an...

Hi all,I am using an ST32F091 micro and using RS-485 to communicate over the UART port. I have a 485 transceiver that handles the 485 scaling part. I am using an interrupt based Rx and Tx on the UART. I am encountering a very weird problem in that wh...

I think thats what I'm leaning towards too now. This was eventually going to be used down the line in production so I was hoping the GUI version had the capability :(

Sorry, I should have been more specific. I am using the UART bootloader to flash the chips with STCubeProgrammer.I successfully flash and set the option bytes to boot into main flash, and the program indeed executes. CubeProgrammer however tries to s...

If you can tap into the UART pins on your target board, I would recommend using a terminal window configured to 115200, Even parity, 8 data bits, and 1 stop bit to try and "manually" talk to the bootloader. If you still cannot get responses, you have...

I can't share any code as it is proprietary.What do you get if you send a basic version command? I believe its an "0x00 0xFF". Also, are you using even parity?

Thank you Imen!I just wanted to clarify that you mean both PA2/PA3 and PA14/PA15 can be used to activate/talk to the bootloader, correct? I know they can both be used for USART2 in general.Thank you again.
