For STM32H7, if the FMC data lines and SDRAM data lines are cross-connected (not D0 to D0), and address lines are also cross-connected (not A0 to A0), can SDRAM work properly? My PCB is about to be manufactured, but due to the hardware engineer’s des...
According to the PD 3.1 requirements (also PD 3.0), I need to connect UCPD1_CC1 and UCPD1_CC2 to USB-C CC1 and CC2 to communicate and request the desired voltage. But STM32G0B1KBU6 has only UCPD1_CC1 available. Is there any way to connect STM32G0B1K...
Hello,the SPI does work with NSSP(Negative Slave Select Pulse-Mode), but it does not work if I disable NSSP. As someone pointed out the SPI NSS(P) may only work if the Pulldown of that pin is enabled, but I’m not 100% sure on that one, but it seems t...
Hi,is there any HW guidelines to configure a USB OTG port with STM32H563VIT6 with VBUS detection?
Hello.I recently experienced an unusual MCU Problem and need to analyze it. Please help me. The FW program download to the MCU is successful, but it does not operate after a reset. I performed a short circuit test after disconnecting the power(Batter...
New question split from this post.One additinal request: When checking if bootloader pin configuration has an impact on the real application it would be helpful to know the default level for output pins, likedoes the UART_TX pin drive active high or ...
Hi,When reviewing the descrption of MCU pins used by the integrated system bootloader, I came across several documentation bugs in the latest AN2606 (rev70). Inparticular, Table 164 lists:USART1_TX pin - PA9 pin: USART1 in transmission mode. Used in ...
I'd like to use a general purpose timer to continuously trigger a rtc timestamp (using H533)Is it possible ?How to map TRGO signal to Timestamp trigger ?(No HAL please, LL or direct register setup).Thanks in advance.
