Roy and Scott,  I modified Scotts python file to emulate what is happening when the config is copied from the D block to the E block. I loaded the resulting file into the NVEM using the STM32programmer at 0x080E0000 as Roy suggested. It seems to work, my NVEM is now functional with the JSON binary, and config. I guess I should note that like Roy my NVEM resets every time it gets a TFTP write request. Attached are my working config memory file (bin with txt appended) as well as the modified python script that generated it. just run the script and a new config.bin is created in /tmp. You can then use the programmer to upload it to 0x080E0000. The config.bin is just the original JSON file with the size of the original file appended as the first 4 bytes. Note the first 4 bytes are 1BBA (the JSON file length), and the whole config file is 1BC0 long (6 bytes longer, 4 for the length which was appended, and there are 2 bytes of zeros at the end to make a block of 8.

Writing it as bin in the programmer did work First it gave an error
  19:03:53 : Error: failed to download Segment[0]
  19:03:53 : Error: failed to download the File
  19:03:53 : RUNNING Program ...
  19:03:53 :   Address:      : 0x080E0000
  19:03:53 : Application is running, Please Hold on...
  19:03:53 : Start operation achieved successfully
Then I looked if the Write protection was enabled, it was not, but I disabled it, wrote the config bit en then set it back. After that I erased the address after that it uploaded succesfully, not sure which one helped.
Did try write the config.txt as bin before, but chose the wrong address I see, I chose the temporary address. And your file has some zeros added.
Uploading the edited config with your or the original python script does now work however. With your script it gives no error, but after a reboot it still loads your config. The original script still a time out. I did try try to enable and disable the other addresses, with no luck. I edited the config.bin and uploaded that one with the programmer, that works

Oops I had to read carefully, now I see the script of spdbmp927 makes a valid bin file to write with the programmer. Scotta maybe it helps to choose another address for the tmp file? Unfortunately I'm getting errors when I try to compile.
Or maybe there is a difference in the option bytes? I don't know if it could make a difference but here are mine:
RDP: AA
BOR_LEV: 3
All the others are checked

I'm still getting following errors btw at whatever settings I choose. Disabled the joints 3,4 and 5 and nvmpg in the config, should that make a difference? Could it be the buffer being too big or memory issues? Fortunately I could still use the lpt port, so no high prio for me

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?

Ok, so the TFTP is failing somewhere as the write request callback is not being triggered for some reason. Could you please try the attached bin which has more debug info output.

Hi Roy, can you please share all of your config files and I will run your config to see if I can help resolve the following errors for you.

Hmm, the next step in the code is to erase the flash. Some more debug code added to the bin file.

Could it be something with the register or control bits?
