Resolved! STM32N657 IO 3.3V tolerant?
Hello,I'm using the STM32N657 processor and have the HEXASPI device running at 1.8V. VDDIO2 is connected to 1V8 supply (which affects: PO[5..0] and PP[15..0]The FMC is placing the A23 line on pin PO1 (this is the only option for the FMC-A23) and the...
Programming stm32h5 board with screen & NOR flash fails: can't erase
I drew a board of stm32h503rbt6, including a screen and a NOR flash. The flash model is mxl6433f. Currently, the problem I'm facing is that when I try to program the board using stprogram, I encounter an error that the programming cannot be completed...
Resolved! L073: ADC & DMA, strange buffer "shift" in CIRCULAR mode
Heyho,strange things happening that I'd like to understand for a STM32L073 (Nucleo for now).Setup on a L073 @ 32MHz:- ADC is clocked by PCLK/4- ADC prescaler = 2 -> divide by 4 -> 2 MHz- 12 bit right aligned- ref V = VDDA = 3.3V- hardware oversamplin...
Resolved! STM32G473RBT6 MCU DualBank Mode Bank-2 Page Erase Silently Fails
Hello! I am working on a custom OTA bootloader system on a STM32G473RBT6 MCU in a custom board I have been using maybe for 3 years with no problem. My board is connected to a Raspberry Pi over RS485 network. My idea is this:There are 3 virtual sectio...
ADC Readings Unstable Under Load with STM32F429IGT6
Hey everyone,I’ve been using the STM32F429IGT6 for an audio project, and I'm running into an issue with the ADC readings. When the system is idle, everything seems fine, but once the load increases, the readings start to fluctuate unexpectedly—partic...
Resolved! STM32n6570-DK - DCMIPP_ContinuousMode
Hi,I would like to recreate the DCMIPP_ContinuousMode example but using the cubeMX to configure the MCU, I haven't found anything online to follow as example.Thanks.
Resolved! STM32H750 XiP Clock change
Hey together, I have a question regarding changing the clock while running in XiP mode. Upfront everything works so far very well. On our STM32H750 we have a very simple bootloader. This bootloader configures the QSPI and the STM32H7 to run the appli...
Resolved! Cannot enter DFU mode on STM32F446ZET6
Hi everyone, I’m working with a custom made STM32F446ZET6 board that otherwise functions perfectly (all peripherals, flash programming, etc. work fine). The only thing that doesn’t is the ROM bootloader. I can’t get USB DFU or UART boot to respond no...
UART idle transmission
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...
