Hello,I am trying to communicate with the bootloader by serial.Most of the times it works nice but sometimes it fails as I fail to enter the bootloader.To give a context, in order to enter the bootloader I set the rts of my FTDI high (this will set t...
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...
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...
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 ...
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.
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...
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...
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...
