Is there an easy way to find devices that support specific CAN buffer configurations?For example, some only have receive queues whilst others allow a number of receive buffers to be configured (which is what I want). I know the H7x7 supports this, bu...
Hello everyone,We are having trouble getting tracing to work with our target at full clock speed and would like to understand why, we have an application running on STM32U575 @ 160MHz CPU clock, we also connected the J-Tracer to it using a connector ...
Hi,I do not plan to use USB, and the STM32N6's VDD is 1.8V.However, creating a new 3.3V power supply just only for the VDD33USB pin is too inefficient.The datasheet lists the absolute maximum ratings for VDD33USB as ranging from 0V to 3.6V when USB i...
Hi, I am tring to write data by the FDCAN bootloader of system memory, my target is STM32H563. Now, I can read the device ID, perform the mass erase command, but I can't write data to SRAM/Flash, the FDCAN bootloader doesn't response any CAN message...
Hello,I am writing to seek advice on connecting an APMemory APS12808 OSPI memory to the STM32H723ZGT6 microcontroller.Initially, I attempted to adapt the code from this thread ( https://community.st.com/t5/stm32-mcus-products/stm32h7-octospi-mode-hyp...
Hi, I am using an STM32F767ZI to communicate with a Dacai HMI display over UART7 at 9600 baud. Sending data from the STM32 to the HMI works perfectly, but receiving data from the HMI is unreliable. The same HMI works fine when communicating with othe...
Hi, I don't know where to post this message. There's an error in the RM0090 Rev21 reference manual, page 121: "bit 15 of the PWR_CR register" should be "bit 14 of the PWR_CR register". And most importantly, the debugger doesn't have bit 14 (VOS) of ...
Hello, I hope to reach the appropriate contact regarding Country of Origin (CoO) information at ST.We have identified a conflict between the CoO listed on the website and other documents (such as PCN and the attached FMD chemical document). These doc...
A new STM32 sub-family (as part of the 'H5 family) came out. They have everything but the kitchen sink. As far as I can tell, 'H5E4 and 'H5E5 differ only in that the higher one has USB-HS with PHY (the 'H5Fx are crypto-enabled variants, as usually) W...
After encountering an issue with a Hyperbus flash chip we moved our flash to what we thought would be a simpler OctoSpi Nor Flash. I am working with an STM32H7S7 chip with a NOR Flash S28HS512T. I cannot get the chip to communicate in the desired mod...
