Resolved! STM32H7 programming w/out STLINK

Hiya. This is my first time working with custom STM PCBs.I was planning on flashing/programming my custom STM32H7 board (specifically STM32H7A3RGT6) over STLINK and then just do general purpose programming over the USB-C COM Port. However, the TAG co...

Resolved! How to flash STM32F429zi nucleo via UART without ST-Link?

Hello,I'm working with STM32F429ZI nucleo board, and I would like to flash my program using UART (USART1 or UART3 via  a usb to ttl converter)  instead of ST-Link.I understand that STM32 has a built-in bootloader that can be used for flashing via UAR...

Resolved! Dual core concurrent access to the same FMC memory address

Hello, We have a STM32H755 with an FRam (similar to SRAM) module attached to the FMC. We have been seeing CPU exceptions when the M4 core tries to access (read only) the same memory location the M7 core is writing to. So, it seems that the FMC does n...

I²C on STM32C011 using PC14 (SDA) not working

Hello,I am working on an STM32C011 (Nucleo-like custom board) and trying to use I2C1 with the following pinout:PB7 → I2C1_SCL (AF14)PC14 → I2C1_SDA (AF14)According to the reference manual / datasheet, PC14 can be mapped as I2C1_SDA (AF14).I connected...

Resolved! DFU Download & Upload only 1024-byte page works

Hello, I'm using WinUSB and I'd like to program the flash memory at address 0x0800c0000 in 256-byte increments. This works fine the frame but every frame after this gets written to blocks in increments of 1024. It seems that if one needs to push more...

Resolved! STM32H503 simultaneous ADC and DAC use

I've spent some time recently trying to prototype a small project based on the STM32H503 which would need to have the ADC and DAC running simultaneously with multiple channels of analog I/O via DMA. I was able to get this all coded up but discovered ...

Resolved! RTC_OUT availability while STM32H7 is powered off

Hi,I'm using an STM32H7 microcontroller and need to get the RTC working.I set RTC_OUT to 1Hz and set the LSE to a 32.768Hz crystal, and inserted the CR2032 battery.When the microcontroller is powered (VDD 3V3), I see the waveform oscillating at a fre...
