I connected stlink to my nvmpg to get a dump of the running firmware, it would be interesting to get a copy from someone that has a working to see if there's major difference? Scott, would you be able to take my .bin from my nvmpg and see if it differed from yours? I dont have the skills to reverse engineer things like you did up front but happy to poke about and learn more!

Great, yes please send me your bin file from the NVPMG and I can compare to the one from mine that was use to reverse engineer the payload. It will be interesting to see if they have made some changes.

Thanks for the pointer at least I now know what to look at. I tried manually uploading the config file but tftp timeouts (ascii & binary modes) as well:

tftp> status
Connected to 10.10.10.10.
Mode: netascii Verbose: on Tracing: on
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> put /tmp/config.txt
putting config.txt to 10.10.10.10:/tmp/config.txt [netascii]

Transfer timed out.

I will download the remora source plus the build system to add some debug messages and  hopefully identify what is happening.

 Attaching the nvmpg .bin I was able to extract from my unit. Hope this helps debug what's going on with the TFT/display oddities!

Hi, thanks but something is not right with the file. It's only 99KB where the hex file I dumped from the MPG with ST-Link Utility is 400KB. On inspection, the file does not look like a valid bin file either.

Let me try once more; quite new to this--This time around: I used st-link utility, from there i plugged address
 
The first time around I had the size set to something smaller as it appeared to be null data after some point? this time i changed the size to 0x07FFFF

New version shows 511KB when unzipped (had to zip to upload here)
 

Hi, the file is a better size but still does not look correct. Please save as a hex file starting from 0x08000000. Below is a snip of a valid NVMPG hex file.
