Good morning,I have a problem sharing a variable between bootloader and application into my STM32F303ret6 uC. I need to write a shared variable to tell the bootloader that it has to wait for new firmware.I read many posts which suggest to declare a v...
I need to establish an Ethernet connection between two embedded devices. From a PC I can connect to my application or to the other device and exchange messages. How do I do this on my H750. How do I open a connection from my device if the IP and port...
Hello, I have a STM32 Nucleo-64 development board with the STM32L476RG MCU on it.. I have made a small PCB that, among other things, brings the USB interface to a connector. I have implemented a simple USB configuration following some online tutorial...
The officially recommended recipe for lwIP on STM32H7 puts the ethernet DMA descriptors in SRAM1. SRAM1 is not zero'd by the default startup code.It's unsafe for the network drivers to assume that buffers and critical data structures live in .bss.F...
HiI found something strange in cmsis dsp source.I am using stm32f429 and LITTLE ENDIAN and cmsis dsp library V.1.5.1.in cmsis dsp library(arm_mult_q31.c) :void arm_mult_q31( q31_t * pSrcA, q31_t * pSrcB, q31_t * pDst, uint32_t blockSize){... whil...
I have found several other forum posts on this subject, and I've tried to follow them, but I'm still stuck. For some reason, SPI3 on my bl47eio1a never enters a ready state. It gets stuck waiting for a ready state before it ever can send or receive a...
I am trying to run the SPI peripheral on STM32H757 using low level drivers but no luck at all. The STM32cube H7 package contains example for controllers which has no FiFO, . Thus the examples cant be directly use. Also i have cherry picked quite alot...
I'm trying to send udp data from stm to server. But when i observe in Wireshark, the protocol shown as ECHO, not UDP. What is the reason?
Hey together,I have a question regarding the STM32H7 ethernet interrupts. I have lwIP + freeRTOS running successfully on the device. All fixes which were indicated by @alister were applied and it runs quite stable. The strange part is that when I ap...
