MSP432E401Y: Which router should I use for firmware download with BSLscript ethernet?

Part Number: MSP432E401Y

We use BSLScripter.exe to download firmware with ethernet and it works, but the problem is if I have my router connected to the office network I get this error: 

[ERROR_MESSAGE]There is invalid TFTP Read Request in the packet received!

If I remove the connection to the office network everything works fine. 

The problem is that we want to run BSLScripter.exe in production, and are planning to have local network for this, with the PC and the sensor, but we need a router to give the sensor a IP address with DHCP, but the question is will the bslscript work then?

Do you recommend any specific router for this or any specific setting?

    Hello Hoffi,

    Most likely, whatever security policies your office network has is interfering with the update here. The Ethernet boot works by the ethernet bootloader sending out a BOOTP request and the BOOTP and TFTP server on the PC should receive it. These maybe blocked on your office's network. 

    Some things we have seen thought that could be issues, is making sure the client and server are on the same subnet. The other thing we have seen is sometimes if a PC has multiple NICs, the BOOTP reply from the server may go out on the wrong NIC. You can avoid this by temporarily disabling the additional NIC.
