Hello - just trying to make a sanity connection to AWS IOT, unsecured port 1883, but it fails with a very non-specific error like not connected. I changed the demo app to use unsecure port 1883 and it connects and successfully sends the MQTT messages...
Hi,We have a custom hardware where we are using I2C interface to program firmware.Have activated bootloader by using pattern 10 as mentioned in AN2606 document.Using I2C3(PA8, PC9) for programming firmware but unable to detect the chip on I2C.Does ST...
1) CC1 and CC2 connections from microcontroller are properly connected to TCPP01-M12. 2) When TCPP01-M12 is separately powered up, input given to CC1 and CC2 appears on CC1_C & CC2_C3) When input to CC1 and CC2 are given from the controller, the volt...
I want to use local bootloader of mcu. First i used to sm32f407vg mcu, than i would to use stm32l052 mcu but i didn't this wit mcu. my tryed code is under of question. i am waiting the advice.void JumpToBootloader(void) { void (*SysMemBootJump)(voi...
Hello,I need an ISR that fills a circular buffer. Data will be consumed in the main() loop and critical section/mutex locking functionality is required to manage properly. So I looked at the HAL UART code for inspiration and came across __HAL_LOCK(hu...
Hello,-> I want to use a third-party TCP/IP stack with the STM32H745-Discovery, and I have gone through LWIP for reference, upon which I got to know that when we enable LWIP and Ethernet from Cube MX it generated ethenetif.c/.h and lwip.c/.h files an...
Hello,can someone give me a recommendation for a 3Port Ethernet-Switch IC, which will work together with AZRTOS. What changes in settings are necessary?I want to built a system with 2 physical RJ45-Ethernet Ports and a RMII conntection to a STM32F407...
NOTE! This is a bug report for all STM32 MCUs with Ethernet peripheral, but it has a highly valuable information for all software development on/for any platform.Compiler barriersThe compiler is not required to keep the code order of non-volatile var...
Hi,I want to know if it is best practice to mix both CMSIS_OS2 API threads and native THreadX threads in a project or should I just port old code over to native THreadX threads instead.I'm building an embedded device using AZRTOS and STM32 Microcontr...
I am encountering a HardFault in the System Timer Thread which I am struggling to understand and resolve. I have 2 threads with the same priority. Each thread also has a queue. The first thing I did when I encountered the Hardfault is check the stac...
