stm32H747-DISCRO NETXDUO iperf TCP only has 55MBits,but UDP have 95MBits,i want to promote tcp speed.so how I do?
CubeIDE NETXDUO configuration keep default#define PAYLOAD_SIZE 1536 #define NX_PACKET_POOL_SIZE ((PAULOAD_SIZE +sizeof(NX_PACKET))*40)

Resolved! Where is the SAI_GCR for a STM32G441 described?
In the reference manual RM440 Rev7 that register is missing while the register is defined in the SAI_TypeDef. I only found a description in the F446 RM0390. Are they the same?
how is SPI5_IRQHandler called?
I set up an DMA spi transfer and I want to essentially remove the irq. I'm already in a IRQ and I'm staring a spi transfer and want to just wait for complete. but I can not find anywhere in the HAL code where SPI5_IRQHandler is called. I decided not ...
Resolved! Hello! May be it is wrong ethernet DMA tail calculation?
In ethernet HAL driver stm32h7xx_hal_eth.c function void ETH_DMARxDescListInit include row: " WRITE_REG(heth->Instance->DMACRDTPR, ((uint32_t)(heth->Init.RxDesc + (((uint32_t)(ETH_RX_DESC_CNT - 1))*sizeof(ETH_DMADescTypeDef)))));"This code adding val...
i got Error: L6406E: No space in execution regions with .ANY selector matching
i used lvgl and stm32f469i-disco and i got many error Error: L6406E: No space in execution regions with .ANY selector matching. i turn off all the file system (stdio,win32,fatfs) because i have no external library (ex. dirent.h and unistd.h forlv_use...
Resolved! Jumping to Sysmem bootloader behaves differently across two STM32F405RGT7 batches
The Question (since this is a little long): Is there any known interaction between the WWDG timer and the bootloader located in System Memory? Is there any known differences in the F405 revisions that could have an interaction between the WWDG and b...
Resolved! bug in HAL_GetTickFreq
The description for HAL_GetTickFreq says/** * @brief Return tick frequency. * @retval tick period in Hz */It returns 1 when the tick frequency is 1kHz. The period would be .001 seconds and the frequency would be 1000 Hz. Based on the typedef below, I...
STM32F7 lwIP Ethernet [FreeRTOS] - TxPktSemaphore not given
I'm developing a device that works as a modbus slave over TCP/IP. For this application I'm using FreeRTOS with CMSIS-v1 and LwIP. The problem occurs sometimes when I disconnect the master (a PC with modbus poll), then the code stucks waiting for a se...
STM32F730, STM32CubeIDE, OTG HS Device with DMA Possible?
Hi,I'm using OTG HS, in device mode, as a CDC VCP. It works when "Internal IP DMA" is disabled. If I enable DMA, the USB device enumerates but CDC_Transmit_HS() no longer works.I saw the article on USB DMA with the STM32H7, and I tried similar things...
