Hi to everyone. I'm developing bootloader for stm32h745. My idea is to rewrite FLASH of the M4(0x81000000) core using proramm executing int M7 core. So For this first i need to stop M4, programm M4 flash and then restart it. The issue is how to stop ...
I have a task which is responsible for triggering a pin, sometimes at a short period of a few ms. I created a freeRTOS Task which has a while(1) loop polling xTaskGetTickCount() with a vTaskDelay(1). If all my tasks have the same level priority ( f...
Can anyone tell me how to activate (which function must I run) the USB if I detect a VBUS on my EXTI Interrupt.My STM32L151 is externally Powered. I activated the SELF_POWERED function in CUBEMX. I monitor the VBUS on an external Interrupt (rising ed...
The lwip stack was initialized by cube mx (no FREERTOS). I follow the chip guide lines for the hardware (like nucleo board but with transformer built into the connector). It seems that with a fast transient on the power supply of the board everythin...
I have a question regarding the logic of the USB cdc transfer. But beforehand let me show you approach up to nowThis is in a rough version my program, It will be used for feedback control. So a fixed frequency of the main loop is mandatory (as I use ...
Hi all.I have a hardware with STM32F469, running FreeRTOS and USB stack as configured from CubeMX.I have the following problem. I have a preproduction stock of this hardware and 2 USB sticks.Let's consider only 2 of the above boards (let them be A an...
I have a hardware timer using its updateEvent interrupt to increment a ms_passed variable every 1 ms. I have a freeRTOS task reading ms_passed ( via TaskNotification ) in a while(1) loop to toggle a pin at a given time interval/tempo based on a vari...
I'm working on a custom board with an STM32F072RB as microcontroller. I'm testing the firmware update via USB and I found that as soon as I jump to the internal bootloader (address 0x1FFFC800) the CPU goes down. Looking at the enables I found that t...
