In function USB_EP0_OutStart is: if (dma == 1U) { USBx_OUTEP(0U)->DOEPDMA = (uint32_t)psetup; /* EP enable */ USBx_OUTEP(0U)->DOEPCTL |= USB_OTG_DOEPCTL_EPENA | USB_OTG_DOEPCTL_USBAEP; }In my opinion enabling endpoint should be out of DMA condi...
So I'm working on a hardware prototype which utilises two STM32F303s on two separate boards. I need to provide DFU firmware update functionality so that a package can update the firmware of either or both chips. The master board contains the USB conn...
I just got the eval board.I am clueless , too much info on the site , can someone point me to a get started pdf or something ? Shouldnt I see the board in the Audiweaver server? Where it now says native?I have Touch FX and the audio weaver ,but neith...
Hi,i'me trying to develop a firmware for STM32F107RCT with a 4 port Microchip switch.The switch has 3 port with phy and 1 port in MAC/PHY mode. I've set it in MII PHY mode.It get's the 25MHz clock from MCO1 pin (set HSE that use a 25MHz quartz) and g...
I have my window comparator fully working Triggering an interrupt every time it crosses the thresholds .But my problem now is how do i know if it is positive or negative edge..?I am using the HAL for this.Thanks
I have a "hello world" example that works fine on a STM32F765Z6T6 (custom board). It basically waits for a USB serial port to be opened on the host side, and outputs "Hello world" every second over and over again. Unfortunately it's based on libopenc...
Hello,I use an STM32F4 as a USB CDC device, I would like to add the MSC functionality (SD card). I have read many threads, but have not found a way to implement it.Is it possible? What needs to be adjusted?Does anybody have found an introduction or t...
I have the USART2 setup for RTS/CTS flow-control and Rx DMA for one byte transfers into a ringbuffer. The problem isn't that the ringbuffer is overflowing, it appears that the DMA process is stalled during the erase flash pages operation and the UART...
Hi,I have a project that needs to transfer full chunk of data from 1G bytes flash memory to computer with 2048 bytes at each tranfer. The total time has to be less than 20min. I am going to use STM32 with ethernet communication to accomplish this.Do ...
Board stm32h743i-eval - STM32Cube_FW_H7_V1.5.0I am using OTG1_HS in dedicated Host mode. It is connected to a single device that contains a built in HUB with 2 devices attached. The main device I am communicating with is an ASIC based image sensor fr...
