Just got my usb-ttl (cp2102), but can't get it working with my router (tp-link 1043nd).
I've soldered the 4-pin header and checked continuity according to the wiki. The terminal (putty) will however only spit out garbled text, it actually looks like a baudrate/parity/flow-control problem but no matter what settings I choose, the output is either garbled or absent.
What I've tried so far;
Connecting only TX/RX - Garbled output that comes in chunks (uboot, kernel booting?), seems to go quiet after a while.
Reversing TX/RX - No output.
Connecting TX/RX and GND - No output.
Connecting TX/RX, GND and VCC - No output.
Verified soldering joints with multimeter, all is fine as far as I can tell.
What could be the problem? Faulty usb-ttl cable?
The router is working fine btw, just wanted to make sure I have serial access for recovery.
Output looks something like this at 115200/8n1 no-flowcontrol:
