Hello, I am using STM32L4 series controller. I want to use USB OTG in dual mode where I want to run USB device and Host on same application. facing an issue when I select USB_OTG_FS as OTG/Dual_Role_device using cubemx tool then in middleware USB_HOS...
I have to deploy an algorithm with a lightweight deep learning-based approach on a low-power STM System-on-Chip based on an Arm Cortex-M-class MCU or Arm Cortex-A-class MPU. Is there a way to reduce cache-misses or a way to reduce the CPU stalls on c...
Hi, i have made an custom external loader for MX25L12833F-STM32L4P5. STM32CubeProgrammer gives me the following errors: "Error:failed to erase memory". Some time it gives me the error: "Error: failed to download Segment[0]", "Error: failed to downloa...
We are using a the Microcontroller for one of our products , we are using two UARTS for communication , however when both the UARTS are enabled we are facing some difficulties in the communication, can anybody help in this ?Attached is the main file ...
Hello Community,I am working on a Vibration Measurement system that will be subjected to lifetime vibrations ranging from 10Hz to 2000Hz at approximately 1g with expected lifetime of 2 years with 16 hours daily vibration & 8 hours of no vibration.I'm...
Hi,We are using STM32L452 for our project.We have problem with pin NRST.We set a 30K pull-up resistor (with pull-down capacitor of 0.1uF).Sometime voltage on the NRST pin is 3.3V and sometimes it is 1.4V.In cases it is 1.4V the MCU is stuck.We think ...
Problem is solved when I put termination resistors in the stard and end of the bus but when I do not do I have a strange behavior of the MCU that I cannot explain/understand.Below you see the screenshot of Yellow: RS485 bus, Blue: The RX Line on the ...
Hi, everyone. I am using stm32l496 and I my application requires me to keep all data in ram after reset. Now i followed these instructions in this link. https://interrupt.memfault.com/blog/noinit-memory it works, like I expected but the thing is I wa...
When debugging custom hardware with the STM32L431KC, the debugger gets stuck in the reset handler:Reset_Handler: ldr sp, =_estack /* Set stack pointer */And in the console it says:Open On-Chip Debugger 0.12.0-rc1+dev-00061-g5e9b46d77 (2022-10-...
Are there any guides or tips on making an STM32 MCU last in a high temperature (~150°C) environment? Specific voltage or clock speed tweaks?The MCU would sleep most of the time, but now and then take and store some measurements.Would certain families...
