1. Introduction and theory When running instance of FreeRTOS on each core, we can implement inter-process communication (IPC) using FreeRTOS message buffers as described here:https://www.freertos.org/2020/02/simple-multicore-core-to-core-communicatio...

Backup SRAM or normal SRAM content is not preserved after reset or wake up from standby. After reset last few bytes written are not kept. What is the problem?This issue appears on STM32H7 devices and is caused by the ECC (Error Code Correction) which...

After re-programming STM32H7 device, I can’t connect to the device. Connect under reset doesn’t help. Why?There are two possible root causes, that can cause this issue. First one is more probable and is related to power supply misconfiguration. And s...

Hello, the TCPP03-M20 contains dead-battery feature, which can't be disabled. So when the device is not powered, it will act as a Sink.For application where this behavior is not wanted (or pure Source applications), the TCPP02-M18 should be used inst...

Hello, you should be able to extract the current data role from the variable DPM_Params[PortNum].PE_DataRole. Usually the PortNum is 0, unless you have multiple ports. This value is automatically updated by the stack.The parent structure array (DPM_P...

Dear all, @HLe.2, @arena_chris1seto unfortunately when LAN8720 is used in REF_CLK_OUT mode (RMII clocks generated by PHY), the timing is not compatible with STM32H7. In that case the RXD output hold is 1.4ns minimum on PHY side, while STM32H7 requir...

Hello @Nsg1987, To use LDO on Nucleo-H745, you need to do HW modifications to the board and also add some additional VCAP capacitors. I think the user manual should provide more information on how to do this, but it might not be trivial task. Best re...

Hello @Ec ,the 192.168.1.10 IP is for the board. I always configure 192.168.1.1 on the PC side, however different IP address from the subnet could be also viable.
