Adapting Mongoose WS for STM32H753ZIT6 with MII Ethernet Mode
Hello everyone,
I am trying to run Mongoose WS on my stm32h753zit6 board but every example they use NucleoH753ZI. They are using RMII mode but in my case I am using MII do I need to update something on library. I tested couple times with different implementations but still my ethernet does not assigning the IP. I am adding the serial log.
Can anybody did this before, can anyone help me about it? @te0...
How to Resolve No Buffer Space Errors in CAN Communication With MCP2515?
I was previously working on a distributed robotic control system where multiple robotic arms communicate via CAN Bus to coordinate their movements. Each arm operates independently, but they share data like position, load, and speed in real-time using the AVR128DA48 microcontroller and the MCP2515 CAN controller. The idea is for each robot to adjust its movement based on data from the others, ensuring smooth, synchronized operation.
Iāve set up the MC with the MCP2515, using Zephyr OS to manage the CAN communication. The CAN initialization seems successful: the CAN bus is set up with a 500 kbps baud rate, filters are configured to allow messages between the robotic nodes, and the SPI interface between the AVR and MCP2515 is working fine. Iāve confirmed this by monitoring the SPI communication on the scope.
The issue comes when I try to receive messages from other robotic arms. The
can_add_rx_filter() function is supposed to catch incoming CAN messages, but it always fails with the error code -ENOBUFS (No Buffer Space Available). Even though I am certain the messages are being broadcasted from the other nodes, my node doesnāt seem to capture or process them. Iāve tested the wiring and termination, and all other hardware connections look good....Solution:
@Dark AI Hey buddy, thanks I tried it out, and also ensured that the buffer and filter allocation matches my system's needs.šš½
