I'm trying to send data from my PC to my STM32 board over USB VCP, but the function CDC_Receive_FS never seems to get called. In fact none of the "_FS" functions in usbd_cdc_if.c seem to get called (except CDC_Transmit_FS) as setting a breakpoint in ...
Hi,I would like to test OTFDEC on STM32U585 to use it inside a custom BOOTLOADER.For my test, I use online website to compute AES CTR on this plaintext data "azertyuioqsdfghj" with the key 0x01020304050607081112131421222324 (I discuss IV further).I s...
Hi every oneI'm developing a project on STM32F746BGT6 custom board which will use USB port for store Data on USB key AND firmware updating purposes (In the Field updating), cause I am newbie on USB things, I am googling about firmware update through ...
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...
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...
