Hello everyone,

I am changing the BCM5241 PHY to ADIN1200 PHY, because BCM5241 is obsolete.

My source code works fine with the BCM5241, but there seems to be a problem with the ADIN1200 PHY.

I use ADIN1200 based on "XMC4300_Relax_EtherCAT_Kit_V2.1" design, after powering on, connecting RJ45 to Laptop, I can't scan BOX, and I don't see ACT LED and LINK LED working.

Please suggest me how to solve this problem, thank you everyone!

Hi, I am trying to get the FPU going on XMC4200 but for some reason I am not able to get the expected performance. I am using the latest version of DAVE.

In the attached project:

1. I enabled the FPU:   SCB->CPACR |= 0x00F00000; //Enable FPU

2. I have two functions, a square root and a multiplication and some pin toggles for time measurements on the oscilloscope.

3. I measure approximately 390 clock cycles for the square root and 26 clock cycles for the multiplication. I think these times are too long and they don't change much even if the FPU is not enabled. So, I think I am not using the FPU correctly.

I would very much appreciate it if anyone can help me to find the problem. I tried all the suggestions in this forum by changing the active project properties but observed no improvement.

I also copied the "main.c" file below, which is the only file that I created in the project.

I look forward to hearing from you. Thanks in advance.

Hello there,
I'm trying to create a EtherCAT slave device based on XMC4800 and ADIN1200. I've generated a firmware according to the "Getting started with XMC4800 EtherCAT" video tutorial (LINK ) on YouTube. I've ran the procedure with DAVE IDE, then I created configuration file with SSC. I tried with both 5.12 and 5.13 versions. Then I copied the XML and Excel files to the TwinCAT 3 IO config directory, which in my case is "C:\TwinCAT\3.1\Config\Io\EtherCAT". The physical connection is made through Realtek USB to Ethernet adapter.
In TwinCAT 3, I created an Infineon master device. However, I stuck at the BOX search procedure. It can't find the BOX and establish a connection between the PC and slave device. All the packages are lost.

On the oscilloscope, I can see that there are some packages coming from the PC at intervals within about one second. However, the LINK and LINK_ACK LEDs are off and also there is nothing on the MII lines. LINK_ST stays at logic LOW...

All the clocks are present. Voltages are stable. Reset is HIGH (3.3V)

My schematic is based on the Relax kit datasheet. (LINK )

What could be wrong?

Please check screenshots below! 

Best regards!

Hello,

I recently acquired the evaluation board in the title. Other than the "Validation set up" in the application notes doc, I haven't been able to locate any user manual or user guide.

When I hook up the eval board input to 400VDC, I am not getting any output. I see a green LED on the microcontroller board, and the red and orange are flashing. The board draws about 4 mA from the supply.

I have ordered an XMC link cable to use the GUI interface, but I was under the impression that the unit would be pre programmed to go 400VDC in 51 VDC out.

Is there any setup guide or troubleshooting steps I should be following?
