I am implementing a firmware-update mechanism on STM32H755 (Nucleo board, MCU rev U) in which the two flash banks are independent. New firmware is flashed by erasing the "other" bank (which is always mapped at 0x0810 0000 and accessed with the ____2...
I have a problem and currently no clue how to further debug. Maybe one coudl help me. I use STM32f4 to capture with ADC1 3 signals with 1Mhz (so 333kHz per channel) triggered by a timer and transfered via DMA. I have a DMA buffer of 3*2*100 (so 100 s...
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...
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...
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...
Hi,I'm exploring using UART idle interrupt on RX to signal to my application that data has arrived.I currently push data into a tx queue then start transmission. I rely on uart tx ISRs to check if there is any more data to send, then load up a DMA tr...
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...
Hi everyone, first, our setup: We're currently developing a custom-made board using STM32U375CGU6Q. We've configured the ADC1 for continuous scan conversion of 9 channels - VSENSE (int. temp. sensor) being one of them - and use the GPDMA to transfer ...
Hello,Is there any chance ST could provide examples or guidance on interfacing a CSI (MIPI) camera with Raspberry Pi Camera Module 2 NoIR cameras?From my initial research, it seems the CSI connector uses the same pin layout as Raspberry Pi cameras. H...
Hello,I am learning bare metal programming for STM32F446RE and am trying to write a simple transmit driver for USART2. I managed to do it but my only problem is when I use HSI 16Mhz clock speed (or anything lower) I get a weird first character. When ...
