So I've installed OpenWRT on HH3A and Netgear DG834GT, LEDE on HH5A.
A piece of cake xD. Now it's time for something harder.
So:
if your BT firmware is older than 8.1.H.J you may be able to avoid JTAG
unluckily it's not my case, so I need JTAG. I've already soldered SERIAL and it works fine.
Everything seems to be well explained on the wiki, but I have some questions as it's my first time with JTAG.
First of all, I would love to use Arduino for this purpose. Found github.com/zoobab/tjtag-arduino, which looks cool and understandable for me (I have some experience with Arduino). But how about TTL levels? Everywhere there is a huge red warning saying "look out for voltage". My Arduino is 5V.
Another consideration - what software to use? github.com/zoobab/tjtag-arduino? Will it be compatible?
If JTAG+Arduino is waste of time, what should I look for? What hardware?
I've found (cheap and) popular hardware in my "local" store.
