Hi Roy,
I think this has something to do with your network / firewall settings as what you are seeing is the watch dog resetting the board as the code is stuck in the TFTP code waiting for something.
It looks like your outgoing port 69 is ok as the NVEM board has received the TFTP request packet. Subsequent packets are sent and received on port 0. Is this open on the PC side?
Using Wireshark would be another help to see the traffic on the network to see where the upload process is stalling.

Yes I've tried a lot today without succes. Tried it on 2 different pc's on linuxcnc, also tried in windows with the python script (that everytime breaks the format of the json) and with tftpd64 which I allowed in the firewall. Tried a crossover cable instead of straight. Tomorrow I will try if I could find something with Wireshark

Here is the Wireshark log, could you see something wrong with it?

Disabling ipv6 didn't (probably to be expected) make a change.

Hmm, not what I was expecting. There is no response from the NVEM board from the write request and you can see that the board has gone off the network with the ARP broadcasts.
Which version of the NVEM board do you have?
I'll add some debug printf's so that we can see where the code is stopping.

No response indeed, but it's resetting after an attempt to upload. With tftp on command line I could connect but, but when I try to "put" the file it also gives a time-out. It's an NVEM V2, I could send tomorrow the memory layout. I saw that the json will be written in the middle of one of latest 128k blocks, is that how it supposed to be?

Yes, blocks 10 and 11 are used as temporary and final storage locations of the config file.

Hi Roy, can you please try this bin file (remove the txt extension) and share the serial output?

The moment it tries to write it restarts it seems.
In stm32cubeprogrammer you could save the memory from the device, maybe I could upload yours with the config included?
