Mine has recurring NAND corruption issue even after I fixed it, I have corrupt NAND blocks being reloaded on almost every startup (visible in the serial console). Originally I was on 2.35 firmware which bricks when corrupt, it would become corrupt after being off for only a few minutes.
It was stuck at the infinitely looping lights on the front panel even after using bootp command to load nk.bin from my computer and then using the NAND WRITE to write it to the NAND (this could also be accomplished by using ymodem transfer thru serial but MUCH slower). I suddenly realized that this message about failing to program the FPGA was important... So after programming NAND (which I had to do every few boots because it would become corrupt again) I then transferred FPGA3000A.bin (for 3000 series) into memory and programmed the FPGA with it, then without rebooting, booted with the boot command. Viola! My machine then proceeded to boot from my 2.35 USB boot disk, and I then hastily upgraded it to 2.50.
Now it boots reliably but on almost every boot it notes corrupt NAND blocks and rewrites them. I think my NAND is not long for this world, but thought I would mention this trick in case someone else gets stuck at the infinitely looping lights and can't figure out why. It seems that the FPGA has to be programmed in order for the infiniivision launcher to proceed far enough to get the machine to boot from USB. I assume that the FPGA data must normally be stored in NAND and this is why mine lost it. NAND alzheimers is a terrible thing.

hi,jake111
how did you program the FPGA in P500?

hi everyone
if you have same issue like this
you can try below method as link

Hello, I am a user of DSO 4104A.
I also encountered the Boot NAND error, and when I tried to download the bootloader, it stopped at around 65-70% during the upload.
Have you resolved this issue?
I have the same issue as you. I have obtained firmware version 4.08

Jedi, I used the recover.bin method from the post above you using 4.08 on a 4104A. Boots into a screen which allows you to touch/click/hit enter and select a ksx/agx to be loaded on to the scope. If you were trying to use the "boot from flash drive" method, I would wipe the drive and make sure it only has the ksx/agx file on it. This method requires being hooked into the internal serial port if that isn't clear.
