There are two situations where I'm unclear on how CAN filters would behave. 1. Direct ConflictOne filter says reject 0x0 to 0x123One filter says send 0x0 to 0x123 to FIFO0 2. Different behaviour for a subset of messagesOne filter says send 0x0 to 0x1...
Hi everyone,I'm using the NUCLEO-H755ZI-Q board and I’m a bit confused about its Ethernet support.The user manual (MB1363 Rev C) shows that both H745ZI-Q and H755ZI-Q support Ethernet using the LAN8742A PHY. It also lists jumpers and solder bridge se...
Can we use STM32N series high end crypto version in medical devices? Currently we are using H series from ST but we are facing some issue in CPU utilization and speed. Apart from external flash is there any major difference where N series is lagging ...
Hi All, Using STM32CubeProgrammer with the ST-LINK in SWD mode.If the RDP flag is set to 0xBB (level 1) and programmed the programmer can no longer connect to the device.How can I reconnect to the device to set it back to 0xAA? _Carl_
Hello ST,The STM32N6 Datasheet (DS14791 Rev 2) claims that the device has 1 HR Timer and 4x 32-bit General Purpose Timers, yet the Functional Overview section does not support these claims. Nor does the Reference Manual (RM0486 Rev 1). Could you pl...
Hi,I am trying lock a portion of Flash memory using WRP(Write Protection). when I am configuring the Option bytes for WRP. I am using STM32L443VC MCU and I have multiple questions:1. Which area to select WRPAreaA or WRPAreaB for page 0 to page 11 bec...
Hello everyone,I'm observing inconsistent FLASH ACR EMPTY flag behavior on two STM32G070RB chips (DEV_ID 0x6460) after a full chip erase by using STM32CubeProgrammer]Observed behavior:STM32G070RB (REV_ID 0x2000): After full erase, FLASH_ACR EMPTY fla...
Hello All,I am very worried about this as time is short.I am attempting to get my STM32L073RZ into low power mode using STM32CubeIDE version 19, and it wakes as soon as it sleeps. I am wondering if this is a problem with my code, or possibly an issue...
Hi everyone,I'm developing a bare-metal application with an STM32H725RG MCU using STM32CubeIDE (including HAL and code generation).I want to use the IWDG1 for reliability purposes, but for some reason, it seems to not work for me at all - upon startu...
