How to check that my hostname is stored in DNS server
Hello,I am working with an STM32F4. My goal is to be able to access to the board using its hostname. From what I've seen, to get it done I have to : set LWIP_NETIF_HOSTNAME to 1 set LWIP_DHCP to 1I also set LWIP_DNS to 1.I made few modification ...
Resolved! STM32H7A3x stack overwriting issue at f_read (SDMMC + DMA + FATFS)
Hi,I am currently developping a custom bootloader to flash my app with STM32H7A3ZIx / SDMMC / FATFS with DMA templateIt fetch a binary (*.bin) from an SD card, read maximum BUFFER_SIZE (=8192) and stores it in a uint8_t RAM_Buf[BUFFER_SIZE] array (8K...
Hello, I try to implement a dual cdc with two virtual port com on USB_FS and HS. Receives callbacks works well on both VCP but only transmit on the first VCP works. When I try to send data from the STM32 to the second VCP, nothing append.
OTG_FS_IRQHandler is endlessly called"signal handler called>() at 0xffffffe9"I have already increase the heap and stack size to 0x2000. I use the STM32H753i-EVAL2 board
Resolved! USB CDC (or whatever else): how do I rename my device?
Hello!Almost everything is in the title. Is there a way to rename the device I'm developing.When I lsusb, it says STMicroelectronics virtual COM port. How do I change that toMyDeviceName?Beside this, is there a need to get a vendor ID / product ID? I...

MQTT broker running on STM32F7
Hi everyone,I need to run a MQTT broker on my board powered by a STM32F746. I managed to get the LwIP stack running properly as a starting point. I verified this by sending and receiving topics with the provided MQTT client implementation of LwIP.LwI...
Use UART DMA with X-CUBE-CELLULAR
Hi everyone,I am using X-CUBE-CELLULAR v6.0 and would like to use DMA on UART to replace the original interrupt receiving method. The original method is calling IPC_RXFIFO_writeCharacter() in HAL_UART_RxCpltCallback() and notify upper layer when an...
