STM32 capabilities
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...
Resolved! How to downgrade level 2 read out protection in stm32f7 board?
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...
Extend bytes for application fw version in the image header
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!
I'm working with a STM32L476 MCU in Atollic, and I have a problem because Read protection mode.
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.
Not possible to connect to STM32H7 in RDP level 1 through CubeProgrammer without disabling RDP
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: ...
How to disable Read out protection Level 1 from STM32F767 microprocessor?
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...
STM32F4 random number generation validation
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...
STM32l432KC can not work after changing RDP level from 1 to 0 although chip was re-flashed new code successfully.
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...
Warnings while using CRC drverfiles
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 ...
