Bootloader on MCU
Hello everyone, i've been coding a bootloader for STM32L072 MCU's, i can download the binary file and write it into FLASH memory from specific address, all this process works, but at the time to jump to the code to be executed, it doesn't work...i ch...
STM32G4 FDCAN HAL Driver Issue (v1.5.0)
The HAL_FDCAN_ErrorCallback is erroneously being called during every interrupt after a Protocol Error (PEA) occurs, even when no error exists during the interrupt. I believe this condition will occur for some of the other interrupts as well (ELO, WDI...
Resolved! What could be causing the STM32L152 UART Rx interrupt to intermittently not fire when data arrives and interrupts are correctly configured?
Hello all,First off, I apologize that I am not able to provide code as everything I have been able to do reproduce this problem is proprietary. Given that, I am looking for advance debugging techniques for diagnosing this intermittent failure of the ...
Which Digital Signal Processor is best suitable for adaptive noise cancellation in a digital audio control system of an Aircraft.
I am trying to implement a system using LMS or RLS algorithms. I will try to choose the best possible algorithms and then implement it on the microcontroller.
Resolved! How to enter STM32L071CB in sleep mode and how to wake it up using LL library?
Hello, I'm working in a project to receive GPS NMEA sentences and send data thru 4G TCP connection every 10 minutes.During 1 cycle all the process to receive and send data lasts about 1 minute, the rest 9 minutes the 4G/GPS module is shut down and th...
Resolved! How does Ethernet RX descriptor wrapping work on STM32H7?
My Ethernet driver is not wrapping as I expect.Section "61.10.1 Descriptor Overview" in RM0399 states that descriptors up to N-1 is owned by the DMA and the DMA continues to process descriptors until the Current Descriptor Pointer == Tail Pointer.In...
STM32F745 USB communication fails
The project consists of STM32F745 MCU and a desktop application. The desktop application sends the data over USB CDC and receives the response back. The problem happens if large data chunks are being sent. What happens is that if several packets of l...
Question about LL CRS initialization generated by MX (USB L4+ or G4)
Cube MX generate the following code:LL_CRS_SetSyncDivider(LL_CRS_SYNC_DIV_1); LL_CRS_SetSyncPolarity(LL_CRS_SYNC_POLARITY_RISING); LL_CRS_SetSyncSignalSource(LL_CRS_SYNC_SOURCE_USB); LL_CRS_SetReloadCounter(__LL_CRS_CALC_CALCULATE_RELOADVALUE(4800000...
How to integrate the STM32U5 Classic Core Middleware (CoreMW) MCU Firmware Package
Wondering how to use the STM32U5 Classic Core Middleware (CoreMW) MCU Firmware Package on GitHub. I am working on integrating USB Device - HID standalone in an existing project. The package does not have any .ioc, .cproject or .project files.
