Hello ST Community,I am working on an STM32U585AII6Q microcontroller with TrustZone enabled. My goal is to revert the RDP level from 2 (0xCC) back to 0 (0xAA) using STM32CubeProgrammer GUI.#### Steps I Followed:1. Defined OEM2KEY in the "Secure Progr...
Update: I found out that HAL_PWR_EnableWakeUpLine() must be enabled to wake up the system.The system now wakes up correctly from Stop3 mode. With the SMPS enabled and all pins configured as analog, the current draw is approximately 12 µA, which match...
I am trying to measure DC output of an RF detector (AD8363) using STM32H723's ADC. The Signal that is to be measured has about 80 mV - 90 mV of high frequency noise embedded on it. Due to inaccuracies in the measurement I am probing the measurement c...
Hi -I am trying to bring up a new design - a 3 phase forward converter, using the HRTIM to fire six gate drives. Under normal design loads it works great, but for normal loading I have the CONT bits set for master and subs. For light loading, I ne...
Hi - I have an application running a 1 kW 500VDC to 25V DC supply for a klystron filament heater. I am using a 3 phase forward converter - each phase driven by a FET half bridge to a transformer primary returning to input mid-point. I drive th...

I'm using STM32H723ZG I want to know if a Timer's update event can trigger SPI transfer without any software interrupts.This is the problem
Hello,I am experiencing an interesting problem on the STM32F303VET:UART1 is used to receive and transmit messages (460800 Baud), DMA1 Channel 4 is used for memory to UART TX buffer transfer, DMA1 Channel 5 for UART RX buffer to memory transfer.Under ...
Hi I am looking into using STM32F446RCTx for my design, which includes 2 x USB FS 2.0 (1 x Host + 1 x Device). Hence need to provide an external HSE. I want to use an Oscillator, meaning I setup the HSE as "Bypass Clock Source" .With this setup I pla...
