Hi. Is there any consideration that I need to take care of when I use HAL_GetUIDw0~2 while ICACHE is enabled?even the simplest project with STM32H573IIK3Q that the ICACHE is enabled will get a hardfault when trying to get UID bytes.This is the whole ...
Is the minimum response time of a OPM trigger defined anywhere? I'm measuring a delay of 50-100ns. I was hoping it would be at maximum a couple clock cycles, but I may be naive. Running on CM4 at 200MHz of the STM32H757i-eval, using Timer8, Trigger...
I am trying to talk to my NUCLEO-F103RB board via my st-link/V2 B202016 but so far I have not been able to. Below is an image of my connectionBelow is an image of my jtag connect I have connected the pins in following order JTAG_Pin 19 -> (Nucleo Boa...
Hi all.I'm working on a project with STM32H7 and I've got a question:I'm doing some experiments with ADC multichannel and wacthdog enabled to launch an interrupt of One of the Channel measured level passes the alert level (High threshold).Everything ...
Hi,New to STM32 I'm discovering the STM32L072CZ, I'm trying to access the AHB2 bus by SWD interface in order to r/w on addresses (say 0x4800 0000 on peripheral GPIOA). When performing a coresight read on 0x48000000 I got 0xBC11477.After checking Ultr...
Status bits in the RCC internal clock source calibration register (RCC_ICSCR) indicate which clock(s) is (are) ready and which clock is currently used as a system clock.Should be the following:Status bits in the RCC clock control register (RCC_CR) in...
Hello all,In my design, I wish to use the STM32H725RGV6 (VFQFPN 68pin)In this package, there is no embedded LDO.There is no explanation or design example for the use the embedded SMPS in this package...should I connect the SMPS output directly to VCO...
Dear Team,We are using the STM32G473VET6 microcontroller with the IMP34DT05TR microphone, utilizing the serial audio interface with DMA.The current buffer size is set to 1000 samples. However, we are encountering an issue where only half of the buffe...
Hi all,we have a custom board with STM32H753 MCU and a DP83848 PHY. When configuring the PHY in loopback mode I can send and receive messages as expected. But when not in loopback mode we can receive data but the Tx path is not working.As the loopbac...
Hi everyone,We are currently designing a board which integrate a STM32L071Ux with UFQFPN32 pinout.In the pin description of this package, it is indicated that pin VDDIO2 supply PA11 and PA12.As we are not using some pins including PA11 and PA12, we ...
