Hello
I'm Isaac. I have a tricky thing here instaling images. I have a USRP
N210 with FW Version: 12.1 FPGA Version: 10.0. When I prove the pps
test, it says: No PPS detected within the time interval. I believe it
is for the FPGA image(v10). So I tried to update the image and
firmware doing: ./uhd_images_downloader.py and later:
./uhd_image_loader
--args="type=usrp2,addr=192.168.10.2,overwrite-safe"
--fw-path=/usr/local/share/uhd/images/usrp_n210_fw.bin
--fpga-path=/usr/local/share/uhd/images/usrp_n210_r4_fpga.bin, only once.
I turned off my USRPN210 and now I can't find it (doesn't have IP
anymore) and any light(A,B,C or D) has turned on.
The interesting thing is that I have a second USRP (N200,FW Version:
12.3 FPGA Version: 10.0) with the same PPS problem and I don't want to
make the same mistake again. So...
1. What do you think I did wrong? ¿Do I have to eliminate
overwrite-safe in the command?
Why did you use overwrite-safe? What possessed you to do that? Most of
the time there is NO reason to overwrite the safe-mode image, since it
is an image specifically to help you get through loading a bad "main"
image.
2. How could I save my first USRP? Do I have to burn the FW and image
with a burner JTAG directly on the motherboard?
Almost certainly you do now.

Any help will be appreciate it.
