I am working on reading an External 3 bit parallel CMOS ADC (4-8 MSPS)(from MAX2771 board or Eva KIT) GNSS digital output through STM32H750B-DK board, Then transmit it over Ethernet or USB2.0 in real time through TCP/IP protocol continuously. then pr...
Hello,I am using STM32L412RB.I have some questions about DFU.STM32L412RB BD is connected to a serial device and receives a specific command.After that It jumps to the corresponding ADDRESS to perform DFU.Occasionally, a failure occurs during the DFU ...
Hello,I've noticed and at last analyzed/debug the nasty situation, where my SSL client task suddenly "hangs" with no further action. I've analyzed the situation and it seems that it hangs on taking a semaphore with infinite timeout inside LwIP part. ...
Hi, I have STM32F407 and trying to write log file (in main loop) with FATFS R0.12c over SDIO. But after few writes I get error:FR_LOCKED // (16) The operation is rejected according to the file sharing policyPreviously I was using STM32F103 and was wr...
This was a ticket I opened this year regarding a fatal flaw in FREE RTOS which I didn't get a final answer or proper solution. Even so the team that I've been working with manage to get a workaround that for now has been shown to be very effective, ...
The error occurred while reading a UART interface (heavy load @ 115200 baud) byte by byte (with HAL_UART_Receive_IT(&huart1, &com_uartRxSignBuffer, 1) ). MCU: STM32F302VB ST firmware version : STM32Cube_FW_F3_V1.11.2Before the RXNE interrupt is disab...
Hello everyone,I'm using the STM32H7 and the new fully reworked ethernet driver along with the LWIP and FreeRTOS for sending and receiving the UDP packets. The issue is first two packets get corrupted when sending. I don't send the UDP packet with ze...
