I tried flashing a project created for the STM32H745I-DISCO board in CubeMx. I configured clock speed for the M7 core to 480MHz and the M4 core speed to 240MHz. After flashing, if i disconnect the board, the deadlock occurs. Then i have to pull up th...
Hello,I implemented a virtual com port using the usbx stack for the stm32U575 in standalone mode and it basicaly works.My problem is that I just can't put more than 8 bytes in the TX buffer at the time. If I do the program gets stuck (in the main loo...
I am working on an application where I plan to relocate all non-safety modules to the CM4 core. To achieve full safety, I need a mechanism to lock the peripherals so that the CM4 core cannot access any peripherals configured in the CM7 core, includi...
Can anyone comment on the prologue and epilogue of following CM7 code, particularly the content of r7 when the routine returns? { 0: b480 push {r7} 2: af00 add r7, sp, #0 if ((ANADIG_MISC->MISC_DIFPROG & ANADIG_MISC_MISC_DIFPRO...
Hi Team,I am observing a shift in a data each time i am sending same data from ESP8266 master to STM32f103RCT6 slave controller but each time i am getting different data and seems to be the shifted data as i can see some part of strings sent. I have ...
Hi everyoneI'm using a STM32F401RCT6 to control a valve actuatorThere is a counter of number of cycles for the actuator (RunTime), and when its value changes, the value of that counter must be stored in the memory for tracking and support.The actuato...
I tried flashing a project created for the STM32H745I-DISCO board in CubeMx. The only change I made was disable a few unused peripherals, enable memory caching. I set the clock speed for the M7 core to 480MHz and the M4 core speed to 240MHz. I add...
Hi, I want to do something extremely basic. Trigger a pulse using software for Timer 1 which is configured in Retriggerable One-Pulse Mode. Background: I can do the above if the Timer 1 is in normal One-Pulse mode. By simply Writing the CEN bit in TI...
Greetings to the community,I have a problem with creating a firmware for the bootloader. I'll start a little differently:Some time ago I made a bootloader for STM32F407VET6. The only thing I did was change the memory length in the STM32F407VETX_FLASH...
Hello,In one of our products we've moved from a PIC32 to a STM32F7. The product is self powered and has a USB connection (USB-Device Full-Speed, HID). Everything works as expected normally. Sometimes however, when I plug in the USB cable, I get an er...
