STM32H743 LSE RTC initialization timeout with external oscillator
Hi,I’m working with an STM32H743 and trying to use the RTC. Everything works fine using the LSI, but when I try to use the LSE (with an external oscillator permanently connected to VBAT to keep track of time even when the system is powered off), I ca...
SPI2 not working on STM32F746BG
I am experiencing an issue with SPI communication on the STM32F746BG microcontroller:Current Setup:SPI2 connected to ADCSPI6 connected to EthernetCurrent Behavior:When testing SPI2 (ADC) alone: Works properlyWhen testing SPI6 (Ethernet) alone: Works ...
Resolved! OctoSPI write operations on memory mapped mode are allowed, but not recommended. Need more info.
Both STM32H730 datasheet and application note AN5050 mentions that a write operation can be performed on external Flash memories through the OctoSPI peripheral.However, the STM32H730 reference manual (RM0468), has the following info on section "25.4....
Resolved! STM32H5 RTC register bug?
HelloI have found a bug that stops updating the RTC_TR register. There is no problem with the RTC clock itself, it is ticking but the content of RTC_TR might in some specific use cases stop updating.I use the latest STM32CubeH5 Firmware Package v1.5....
USB PD sink EPR availability
Hi, we are developing a USB PD sink device which will operate up to 28V @ 5A.The STM32G431 seems to be ideal for our application, however it seems that there is no official support for EPR within the TCPP software yet and I am unable to set a PDO hig...
Resolved! STM32G0B0RET - SFTRSTF not working?
Hi there,ContextI implement a basic code where I check the reset cause flag SFTRSTF (i.e. software reset). If this flag is active, I activate the LED on (LED off otherwise).I read out the reset cause from:uint32_t myResetCause = RCC->CSR; RCC->CSR |=...
STM32H7S7Z8J6 XSPI1 interface
Hi all,We have a question regarding the external memory interface connected to XSPI1 on the STM32H7S7Z8J6. We use the APS6404L-3SQN-ZR 64Mb external ram. We activated the XSPI interface with the following parameters:We also created the memory partion...
Resolved! USB PD + USB Communication STPD01 + TCPP02 + STM32G0
Hello, I made a design aligned to the STEVAL-2STPD01 (just one channel). The USB D+ and D- are connected to a hub (upstream) that is on the same PCB. If I connect the USB-C cable to a laptop, the laptop starts charging but no USB device on the hub ...
Resolved! RTC LSE not working on power off with Vbat
I'm using the stm23F103C8 and I would use the RTC internal cloak/calendar. The program is working fine and I have used the LSE osc (32KHz..) as clock source. I have connected a 3V battery to the VBAT pin. My problem is that the switching off the main...
