Resolved! STM32 dev kit with DSI and demo software playing video from SD card (ideally using DMA)
Hi,couldn't find any STM32 dev kit that has DSI display interface and a demo where it plays video (or at least graphics) directly from SD card using DMA.Which ST dev kit does that? Thank you
STM32H757 SWO Debug Error
I get the following error when trying to debug an STM32H757 with SWO enabled. Failed to enable SWV configuration.Failed to execute MI command:-data-write-memory 0x5c003010 x 4 0x77etc...It would seem the debugger (ST-link v2) is not able to read the ...
STM32G030 RTC LSE clock instability
I tried to use internal RTC with LSE clocking in device which has GSM/GPRS module (GSM part decoupled from MCU part by ferrite beads in power lines and resistors in data lines). In first PCB revision (no separate ground region under crystal) I notice...
Resolved! STM32N657 - eMMC issue
Hello,Our board has an STM32N657 MCU connected to an IS21S08GA eMMC.We use an 8-bit bus, and SDMMC1 is configured to run at 32 MHz.In polling mode, read/write operations work, but are very slow — it takes about 1–2 ms to read or write a single block ...
STM32F407 decoupling capacitor 100nf or 10nf
The power supply scheme indicates to use 100nf for vref and vdd, but in the General PCB design guildines section (Figure 51 and 52) indicates that 10nf power decoupling capacitor should be placed. I am confused which capacitor is suggested for adc de...
Resolved! ST-Link not properly resetting STM32
Hi,I am trying to solve a strange programming related problem I am now having after updating the reset circuit of my STM32F439-based board. Below is a comparison between my old and my new circuit:The reason I made these changes is because this is a l...
Series resistor for high speed signals in STM32H757XIH6
We are planning to use STM32H757XIH6 as a soul microcontroller, so we are using 10/100Mbps Ethernet, is 22 ohm or 33ohm resistor best suited for this application. If either of this is answer , please provide why one is better than other and when.
Programming a virgin STM32G0B1
I'm trying to program a virgin SYM32G0B1 with the code I've developed and successfully run on the NUCLEO-G0B1RE/NUG0B1RE$AU2 development board. I'm using the STM32CibeProgrammer 2.20.0 software and an FTDI cable (TTL-232RG-VIP-WE with the Vcc line co...
STM32N6 Debug Jump From FSBL to Secure Application
Currently, I have a project using a secure application for the STM32N6570-DK. I am able to run and debug the FSBL and Application with the system in Dev Boot, but have yet to be able to attach and debug when booting from the external flash (Boot1 and...
