Hello, I noticed a thread you created a while ago:

I'm attempting to program through USB-Blaster II to a DE0-Nano device on an ARM Linux computer; did you find a good solutions? Thanks.

Hi ASIC,
Dave already describe your options very well! As he describe it for me in the past! When I still need to program with the USB-Blaster I use x86 machine with quartus.
Otherwise I use JTAG with my specific setup.
So for my setup it's working fine. Here what my setup is:
Embedded ARM board with 4 GPIO connected to the Cyclone 4 JTAG lines (TCK,TMS,TDI,TDO).
Using the Jamplayer 2.5:
https://www.altera.com/download/legacy/jam/dnl-player.jsp Implement my own jam_jtag_io() function to do one clock for the JTAG something like:
1- Set clock to low (TCK)
2- Set TMS value
3- Set TDI value
4- // Should wait half period but I don't since my current implementation is really slow go max to 20Mhz
5- Read TDO
6- Set clock high (TCK)
7- // Should wait half period, I don't
8- Set clock to high (TCK) // This is to be sure to always finish at low
Now to work with the jam player you need a .jam file:
1- Open Quartus and generate a .jic file in my case.
2- Convert .jic to .jam with "quartus_cpf -c file.jic file.jam"
Then you need to copy the jamplayer and the .jam file on your ARM board and program the FPGA:
1- jamplayer -aconfigure file.jam // Wait for 25-30 minutes and success message. This depends of the size of your .jam file
2- jamplayer -aprogram file.jam // Wait for double the time of the configure and success message
I always reset the FPGA with another gpio (NRESET) and 2 more to look at the FPGA status CONF_DONE and STATUS.
Recommendation keep the length between the gpio and FPGA JTAG as short as possible.
Hope it can help,
