Hello, I have a problem that I am having a hard time figuring out.My project is using an STM32H743 as a USB host on a custom PCB. Both OTG_HS and OTG_FS ports are connected to different devices. OTG_HS is using the internal PHY and operating at full-...
Hello everyone,I am trying to bring up a NetX Duo TCP Server on the STM32H755ZIQ Nucleo board using Azure RTOS ThreadX + NetX Duo, but I keep running into issues during initialization and runtime. Unfortunately, I haven't been able to find any fully ...
Hi,I'm facing some issues with some STM32G474RET6s, and want to rule out counterfeit chips, even if that seems unlikely.After googling for some solutions, I confirmed the AP IDR register and the DBGMCU_IDCODE both hold a revision ID of 3, which I exp...
Dear all, i have a problem with my custom board based on STM32H745.I need to use core M4 with USB_HS host with mass storage class (a pen drive) at 12Mbit full speed (internal Phy transceiver).I have configured the processor as per attached file (core...
Hi everyone,I am using a STM32H563RG and I need the RTC to work even if the VDD is powered off. To do that, I am plugging a battery on the VBAT pin to power the RTC and the Backup domain. But I tested it and it seems the RTC is stopped and the backup...
I am using STM32WB55 and entering STOP2 mode for low-power operation.RTC Wakeup timer is configured, and the interrupt works correctly in RUN mode,but the MCU does not wake up from STOP2 mode when the RTC wakeup interrupt is expected.Configuration:- ...
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
CNC material affects EMI, thermal dissipation, and grounding.I found this CNC material selection guide helpful:https://www.justway.com/blog/CNC_Machining/How_to_Choose_the_Perfect_Material_for_CNC_Machining_A_Comprehensive_Guide_fb9e953e.htmlHow do y...
Content:Hi,I am using UART on STM32G4 in interrupt mode (RXNEIE + NVIC enabled). I observed the following situation: 1. A byte is received → RXNE = 1 2. At that moment, UART interrupt is disabled (critical section) 3. Later I re-enable the UART inte...
I am attempting to reconfigure Pin 8 (datasheet default assignments are PB6/PA14-BOOT0/PC15-OSCX_OUT) from PA14-BOOT0 to PB6 GPIO Output Open Drain (GPIO_MODE_OUTPUT_OD) a short time after start-up.My current attempt (code below) does not accomplish ...
