AM2612: Profinet Fast statup time measurement

Part Number: AM2612


Hello TI team,

I am currently working with the following setup:

  • AM261x-LP
  • ICSDK_10_02
  • S7-1500-PLC

According to the TI Profinet documentation, the fast startup time should be 625 ms. I have followed all the recommended steps, including setting the device to “priority startup” in TIA Portal and building my code in Release configuration from CCS. However, I am consistently measuring a startup time around ~870 ms.

Could you please help me understand where I might be going wrong? I have attached links/photos for your reference.

  • Hi Parag,

    I would recommend to use latest release using am261x_revA if possible, using default config from demoApp and MCU plus Sdk v11.00.00.29. Size of PN Config data stored in EEPROM is important and can increase startup time
