AM263P4: AM263P Profinet Bootloader

Part Number: AM263P4
Other Parts Discussed in Thread: LP-AM263P

Hello,

I have encountered a perplexing issue with the Profitnet example in the Industiral Comms SDK. Everything works fine if my unit is flashed with the null bootloader from MCU+ SDK 11.01.00.19 but when I update to the null bootloader in version 2026.00.00.06 I encounter an issue.

  • This is all with the example in the Ind Comms SDK 2026.00.00 with no modification.
  • This is all with Industrial Comms SDK 2026.00.00 and MCU+ SDK 2026.00.00.06 being used for the application.
  • This is with the LP-AM263P Launchpad

Steps to Reproduce:

  1. Flash Null Bootloader from MCU+ 2026.00.00.06
  2. Start Debugging Profinet example 
  3. Device will come up and print to console the expected information, but ethernet will not work
    1. Both ports will have the right Green LED on constantly
    2. Proneta will fail to find the device

I have tried looking at the differences in the bootloader itself and the SDK and haven't found anything that seemingly would cause this yet. The bootloading code was unchanged except for making the restricted memory region configurable.
