Resolved! EEPROM Emulation
A while ago a member of ST staff kindly helped me on this forum with adding EEPROM emulation to my design (at the time based on Nucleo-F401RE) by directing me to here....https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM32F4-D...
STM32H523 memory map
Hi,There seems to be an error in the reference manual RM0481 Version 2, page 264, table 48.In the circled image I believe this should be 0x08040000. Can you anyone please confirm my deductions?Kind Regards,Shane
Resolved! Keeping peripherals in perpetual reset
Is it ok to keep unused peripherals in perpetual reset, by leaving their RCC_APBRSTR_*RST (or similar) bit set?Maybe differences in power consumption?This is not for a specific STM32 family.I'm just looking for advice by people with more experience, ...
Resolved! Synchronize peripherals SAI & I2S output clocks
Heyho,I'm using a H733 with both SAI 1 and SAI 4 with SAI 1 as I2S clock master to get 8 synced audio channels.Audio clock comes from I2SCKIN, this is used for SAIs and I2S.Problem: because of the fixed oversampling ratio (256 or 512) of the SAI, I h...

Application booting issue after FW upgrade using ROM bootloader
Hi, I am using STM32U575 MCU and implementing firmware upgrade feature in it using the ROM bootloader. The application code boots the bootloader by calling the following function. The firmware upgrades correctly and I verified that all the bytes are ...
Resolved! STM32G431 Encoder Mode Issue
I have configured the timer clock to 170MHz. According to the datasheet, the maximum fENC value is 42.5MHz when the timer clock is 170MHz, and the tW is specified as 2~3Tck.I am using a quadrature encoder with two channels that provides 1024 pulses ...
