Some parts of the computer can not read the STM32 bootloader in the device manager after connecting to the computer via USB, and the Unknown device will be displayed, but if you change some computers, you can read it correctly, and ask what this driv...
Hello community, I'm struggling to get the dual bank feature to work with the STM32F765 as in the X-CUBE-DBANK-F7 example shown. Following situation:I have two similar FWs, only a different LED is toggled. In the OB I set the nDBank to 0 and defined ...
Hi,I am trying to make the jump work with an F103RC, and have read many posts in this community, but the jump simply does not work for me. The jump code is mainly from DavidNaviaux in the following post:https://community.st.com/t5/stm32-mcus-products...
I have the following problem with my STM32H743:I want to use the ADC3 for an injected conversion, but the ADC3 interrupt does not call the ADC3_IRQHandler, instead the SysTick_Handler is called whenever an ADC3 interrupt happens. When I read the ISP...
Hello!I'm facing an odd problem with STM32H750VB MCU and the USB Host routine on a custom board. I'm working with the latest HAL (v1.11.2) at 400 MHz and USB using the 48 MHz internal RC, "host only" mode + FatFs "read-only". The software is quite si...
Hi,We try to send an receive data to the external APS6404 RAM.Therefore we read the application note AN5050 and copy the function from page 55 (7.2.5).At first the function HAL_RCCEx_OCTOSPIDelayConfig() we cannot find in the library.What is correct ...
Hi all,we are encountering difficulties in activating the compensation cell option. Even if the SYSCFG_CMPCR bit 0 has been configured as 1 we never get the READY in bit 8 (always 0).Various tests have been carried out, but to no avail, so let's star...
Hello,I'm working with two F4 STM32 boards using the SPI communication.The two boards are connect to each other using the SPI1 connectivity. The first board is configured as a Master and only send data. And the second is configured as a Slave and onl...
Hi, I've got an application which is running on an STM32F746ZGT. During in the field firmware upgrades, it has to erase part of the device's internal flash memory and then write to the flash. The problem I'm trying to overcome is to enable the device...
I know TZEN is used to enable TrustZone. At first, this made sense, but now I think about the MCU implementing the Security/TrustZone, and it sounds strange that TrustZone can be disabled. So my question is, what does it really do ? Does it really s...
