Hi,I would like to move my project to STM32 from another MCU.There are some requirements that I have to comply with and I would like to know if STM32 is a good idea or not.I need to be able to flash the firmware using USB without an USB to UART conve...
Hi everyone,I was trying to protect my code by read out protection. But before uploading program, mistaken changed the read out protection to level 2 using of stm32 utility software. Now, I don't able to connect my board to st-link.After search for t...
For our application, we require more than 2 bytes to identify the fw version. However, the current SBSFU has only 2 bytes fw version in the header. What is the easiest way to add a few more bytes for fw version? Thanks!
Does anyone know something about it or similar cases?Is there some registers in HSE clock that can affect the RDP registers?Is it possible to be a bug in CubeMX?Or the problem is in my hardware?Thank you.
I'm implementing in my firmware on STM32H7 the change of RDP Level. In RDP Level 1, I can still connect through ST USB bootloader by setting signal BOOT0 (as expected). However when I connect to STM32CubeProgrammer, it asks if I want to disable RDP: ...
Hi, I'm developing a project which is already quite advanced, and without any change that I have awareness, the microprocessor is protected. 1) What could have produced this change unexpectedly? untill now, I've worked a lot with STM32F103 microproce...
Hello all,I am working on a cryptography project based on STM32F407VGT micro controller, in which I need to generate random data using inbuilt RNG peripheral. I dump this random data to my Ubuntu 16.04 host machine using USB in CDC mode and using l...
Dear everybody,I have a STM32L432KC chip.Firstly, I flash code and set RDP level 1 and PCROP_RDP flag to 1. => everything works fine.Then, i want to reflash code, so I changed RDP level 0 to 1 -> Chip mass erase and flash code again. But chip seems n...
Hello All,We have designed a custom board with STM32F777IITx MCU on it, where i am using ST Micro's CubeMX with Atollic True Studio for developing the code.Now I am also using a USB host peripheral and reading data from USB device now this data read ...
Hello,I'm trying to get LwIP working on a STM32F769I-DISC1 board but with the SBSFU bootloader.I started out with a basic project, generated with CubeMx, that sends UDP packets every 500ms (no operating system, just LwIP Raw API). This works, the boa...
