Hello,I've migrated an application from STM32L496VG to STM32U595VJ.Pin A11 is used as capture input TIM1_CH4.With U5 device the input on PA11 couldn't reach full level at 3.3V. I have the same behavior with 5 MCUs STM32U595VJT6 and PA11 is connected ...

Hello,I have 10 devices STM32L496VG in Dual-Bank-Boot mode with the identical firmware in BANK1 and BANK2.In 5 devices is booting from BANK1 enabled (BFB reset) and in the other 5 devices is booting from BANK2 enabled (BFB set).I would expect the sam...

I've read often about strange problems with activated D cache on M7 core and how it can be solved here in forum.But the STM32F7xx family has implemented a fast DTCM RAM that is accessible from CPU core and DMA peripherals.This DTCM memory should have...

I tried to update an existing and working STM32F7 project to the new ethernet driver.(MCU STM32F777BIT6 / STM32Cube FW_F7 V1.17.0 / CubeMX 6.6.1)But there are some problems with this new driver:1. A Bug in generated function "ethernet_link_thread" in...

Other solution is routing the UART RX line to a second pin with dedicated timer capture input functionality.With first rising edge of RX line the exact timestamp can be captured. A further read of the current timer counter value at interrupt entry gi...

If you have a lot of static or global data move it from initialized to unitialized data section (e.g. with prefix __no_init, depending from your compiler)!Initializing data will be done at startup (before entry to main function) on startup clock freq...

Hello,try this solution:Solved: Problem with Pin A11 on STM32U595VJ - STMicroelectronics CommunityShould be the same problem with USB stuff on PA11/12...

Finally I've found a solution to configure and use PA11 (and probably also PA12) as normal GPIO (instead USB):SET_BIT(PWR->SVMCR, PWR_SVMCR_USV); SET_BIT(PWR->VOSR, PWR_VOSR_USBPWREN | PWR_VOSR_VDD11USBDIS);It is important to set also the PWR_SVMCR_U...

Hello @Diane POMABIA,PA11 is directly connected with comparator output pin 14 of MAX9144 (4 comp IC), nothing else.PA12 is grounded and configured as analog input, because it's not used.You can see the hardware connections in attached layout. There a...
