hi
if i connect the tx and tx together , for example 1 tx from the pin 1 tx from the trace it short the board and the hdd wont spin unless i release one of the tx point .
what i did notice is when i short them out there is some art effect on the terminal windows . but that just nonse i know.

i did not get any output while tx/rx were alone or rx tx together , no output at all .


should i type any letter ? or there is forbiden letters.



by the way, as u seen in the picture , i have not connected the 1.8V to one of the hdd pin . (not sure if this necessary , only tx and rx was)

you connect like:

HDD TX - Serial Adapter RX
HDD RX - Serial Adapter TX
HDD GND - Serial Adapter GND

TX = Transmit
RX = Receive
GND = Ground

transmit one side, receive the other

you don't need 1.8v, you DO need Ground

i meant to connect the adapter's TX to its RX, without hdd . Just to test if your adapter is working. you should see the characters you type appearing in your terminal window (without local echo enabled!)

Honestly, this thread went beyond all imagination. What the crap we are doing here if you can't connect 3 wires?
You should admit it does not work for you and decide what to do with the drive, bin it or ask pro help.

hey
idk why you so upset , if i already explained and said , no output whats so ever on the hdd.

the adapter works , i have connected it to a different board (not related to hdd) to read out UART from it. and it worked .

and if i connect the tx to rx on the adapter itself i do see art effect

40+ posts and we are still at where we were in the beginning. If the hdd spins up then you must have get something on the terminal.
You got tips, please get back when you have the log, we can't help you more, we tried to give you all the info you need at this stage, yet no result.
btw, i was not upset, just wrote what i thought.
