Need help installing mesa 5i25 and g540 .

I have downloaded software from mesanet (5i25_g540). Unzipped (mesaflash, xml, bin, pin) also under utilities (hostmot2).
Which directory should I be in when using mesa flash ? Also do I just copy the hostmot2 file into the configs dir. ?

It really does not matter where the bitfiles go as long as mesaflash is run from the same location
so it can find them ( it looks in the current directory or any path you supply )

So for example if the bitfile you wished to write was in the current directory you could type:

sudo mesaflash --device 5i25 --write 5i25_g540x2.bit
