Our project is targeted to STM32H7, but that may change as new processors become available. We want to include fast external memory and OCTOSPI seems the be the best approach. If there is no available Nucleo for STM32H7 with OCTOSPI, would it make se...
In a Debug session, I pressed the 'Disconnect' button - and this happened: This is on Win10-Pro, and using the ST-Link (converted to J-Link) on a B-L027Z-LRWAN1.Is this a known deficiency, or should it work ?What is (or should be) the difference betw...
I have a board which uses STlink V3 mini serial port. Is possible to see or write into that port from CubeIde?
Hello everyone,I am working on STM32L073RZT6 microcontroller and I have designed my custom board using this mcu. I am facing issue related to reset. The microcontroller is getting rest automatically however the period is not fixed.I understand the po...
According to the datasheet a 10uF should be considered at VDD and 1uF at VDDA.Are these values mandatory for a robust design? I’ve checked various STM32L0 schematics on the internet and most of them use only the 100nF capacitors.I’m asking this quest...
Hello,I'm looking into a potential 8-bit wide bus to transfer data between a STM32F765VIT (LQFP100) and a MAX10 FPGA which are close to each other (less that 30mm), to potentially back up a USART link between the 2. The goal is to be able to reach tr...
Hi,So far I was using Nucleo WB55 and everything was ok with ST-LINK. Now I created new project and switched to Nucleo H723ZG. When I try to run or debug I receive message:No ST-LINK detected! Please connect ST-LINK and restart the debug session.The ...
Hi, I have an STM32F373. If I have the VREFSD+ tied to 3.3V and have it set to Forced Externally using VREF pin in the SDADC1 of the .ioc file, then the MCU will flash properly.However, if I disconnect VREFSD+ from the 3.3V, and set it to "Forced In...
I am planning to use stm32f767 mcu. I am confused to use clock for the same. I am referring discovery board schematic but in that NZ2520SB-25.00M is used for MCU and Ethernet controller. In my case i won't be using ethernet. I will be using TFT inter...
