hi, In final end product we can't use the programmer for firmware update or upload the new program to chip . We need easy solution that compiled program in binary file has to be programmed in chip from SD card or USB Pendrive . In filed very difficul...
Hi,I'm currently developing a PLC-like device based on a STM32F429ZI. It works with FreeRTOS, and the I/O logic is implemented in a single C function, which only accesses a couple of buffers (the locations of which are known prior to compilation). Th...
I am using STM32F746G-DISCO board.Configured USB FS in MSC HOST mode.After connecting the Pendrive, ReqStatus in following part returns USBH_BUSY case ENUM_IDLE: /* Get Device Desc for only 1st 8 bytes : To get EP0 MaxPacketSize */ ReqStatus = U...
HiI work on stm32f746 discovery and I want to configure FATFS on external sdram. I use STM32CubeIDE 1.6.1. when I create my project and mount disk, return error (value 13 = FR_NO_FILESYSTEM). does everyone know about this problem or is there any samp...
Hi .I have STM32H745II controller, I am keeping its boot pin at HIGH state and providing reset condition.Host controller's SPI pins are connected to SPI3 pins PC10, PC11, PC12 and PA15 of STM32H745II for communicating in SPI boot mode.Here STM32H745I...
I am sending with CDC_Transmit_FS by USB CDC, but USB_TransmitCplt_Callback is not called unless the other computer receives it on the COM port.How do I time out or abort a send?MCU: STM32L433CCUxLibrary Version: STM Cube FW_L4 V1.17.0
we are planning to use STM32G0 for our next generation design with its USB port, two application is considered:Use it as VCP, the signal from PC is +5 Volt, but the MCU is +3.3 Volt, can the USB port DP/DM pin directly connect to MCU pins? or require...
Hello,This is nur. I need your help. I am working on STM32F769 phy chip , RMII interface. Once I apply power the stm chip then Ethernet cable clicked , there is no connection. if Ethernet cable does not click into place before power is applied to the...
My SysClock is 200 MHz, AHB Prescaler=1.I want to slow down some timer to filter glitches from external input.But when APB2 peripheral clock is set lower than 50 MHzthe Ethernet DMA does not send any data: no ARP, UDP or TCP.Even when ABP2 timer cloc...
