I'm developing firmware update for an application based on a STM32F072, using the built-in bootloader via UART1.The method to enter bootloader is jump to Bootloader addres (as found on ST community discussions).I managed to get Bootloader commands wo...
Hello,I'm using STM32H747I-DISCO Discovery kit with STM32Cube_FW_H7_V1.6.0 and currently doing some USB testing. So far everything works fine and I was able to get to work everything I needed, but I'm unable to turn off external VBUS. The board conta...
HI, I have STM32L476RG nucleo board. I have interface a SD card using SDMMC. I have configured SDMMC as 4bit mode with TX, RX in DMA mode. I have configured FATFS. I have given 47K pull up to DO to D3 and CMD line. I am using CUbeMX 5.5.0. The FATFS ...
Hello all,2 more questions on STM32 USB CDC1) I see that it works fine for ASCII files, but when I transfer a binary file it does not. Any advice or parameter I missed?2) I get the interrupts, but how can I get an indication that the transfer has fin...
Another question:I see the the transmit and receive buffers are 2048 bytes longBut the Rx interrupts I get are after 64, 100, 164, 200, 264, 300... Bytes. Why is that ?Eli
I am using an STM32L0XX on a Nucleo-64. I am Trying to communicate with a sensor using SDI12 protocol (1200baud 8-bit even parity).To communicate properly you have to implement a question and answer session. To start with a 2-byte question response...
I use STM32CUBEMX to create code,and when the code is running,I find a problem.My code is stuck at prvCheckTasksWaitingTermination.(stm32f405 + st25ru3993)Simple Description with my system:1,freertos use systick, and HAL use TIM72,two simple task,one...
We are creating updated versions of our products; existing products are based on STM32F411, the new product versions are based on STM32F446.We have previously developed a custom firmware update tool - used for field firmware updates by our customers ...
Using Ubuntu dmesg | grep usb, "device descriptor read/64, error -71" is reported. I am beginning to suspect an issue with the USB CDC for the STM32L082 device. A recent community discussion alluded to a "device triad", class, subclass and protocol, ...
Hi,Is there any issue if in STM32H743ZI, ethernet driver I call:…. SCB_CleanDCache(); SCB_DisableDCache(); HAL_ETH_Transmit(&EthHandle, &TxConfig, ETH_DMA_TRANSMIT_TIMEOUT); SCB_EnableDCache();...so far, it works perfectly until now instead ...
