We are using I2C channel 1 for EEPROM and RTC (Semophore used for exclusive access) and I2C channel 2 for Touch controller. Both I2C runs at 400KHz. Everything works normally, Suddenly I2C channel 1 becomes busy at random time. It is really hard to r...

Hello, We are migrating from STM32F769 to ST32H743 controller and we have a unique requirement to have single hex file for both controllers to address backward compatibility in the future. The plan is to detect the controller in the runtime...

Hello,I have a use case to start user boot loader from 0x08020000 instead of 0x08000000 and 0th sector at 0x08000000 will be used to store read protected user data because of the sector size.As per guidance from @Community member , i have made chang...

Stop flag is not generated with STM32H743BI manually written i2c driver.

STM32H743BI, I2C becomes busy after two hours or five hours randomly. Some times there is no issue.

Is it feasible to have single hex for both STM32F769 and STM32H743?
