https://my.microsemi.com/AWelcome/HomeRNew.aspx
Inside the zip there's only a single .bin file with the same name with square brackets, that seems weird, and no instrucrions at all.
Old update instructions I found report other 2 files with extensions .fs and .bt
ftp://anthonygregory.com/Upgrade%20to%20Firmware%20Version%208.x.pdf
--- End quote ---
anenni, how did you get access to the file as it seems like its locked on the microsemi site.
smgvbest:
register on the website then try to download the file.
it will tell you that you need approval, complete the request.
they completed mine in a few days.
I do have the files you get attached

Just for a FYI
I ran the bin file thru binwalk and we can see these

Does any one have all the update files for any version of of the NTS-200?
looks like there should be atleast 3
bootloader
filesystem
and the main program
might help figuring more out
I would really like the filesystem one. a look at etc/passwd would help and more importantly removing passwords from accounts where we don't know the passwords i think would be helpfull

Adding a little more information here
the GPS systems in the NTS-200 is the
GP2015/GP2021 and P60ARM
The GP2015 (RF Frontend) & GP2021(GPS 12 channel Correlator) process the GPS signal and pass it to the P60ARM (ARM Processor)
the 1 PPS should be available on pin (32, 68 or 80 of the GP2021) depending on how the registers are setup.
Will track down where this is available later.
It also looks like the J11 connector is the JTAG connector for the P60ARM (Pins 67-71)
Will figure out pin out later.
my un-educated guess at this point is the code in the P60ARM is probably where any patch would occur
attached are datasheets for the 3 component mentioned as well as
photo's of the components
GP2015
GP2021
P60ARM
