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...
Hi all!,In the case of a commercial device, who need periodic firmaware updates, is there a way to protect those updates in order to avoid for being copied and cloned?Someone can point me to a read about it?
Porting NUCLEO-H753ZI/Applications/1_Image to STM32H753.This is running on STM32H753I-EVAL2 board.The bootload can be done in 2 steps (download SBSFU.bin, then download UserApp.bin) or in 1 step (download SBSFU_UserApp.bin). The behavior is the same:...
Hi, I am coding on the NUCLEO H753ZI board with the pack for embedded cryptography (x-cube-cryptolib-3.1.2). While this folder provides example with hardcoded keys, it does not provide an example with keys imported from a file. Typically, I would lik...
