I've been searching around for anyone who had experience or ideas about serial console on LS-VL but could not find any definitive answer for this particular model. The guide for attaching a serial cable to the board is pretty straightforward, but looks different than my board in LS-VL. Through a poor Google translation of a thread on a Japanese forum (see comment #5833 and #5835), I can see that it's pretty much the same as in the guide. However, what stopped me from soldering the Nokia CA-42 cable to the board is this Japanese article that talks about additional modifications that need to be done to the board in order to have serial port enabled. Is it really the case? Or can I just follow the guide on the wiki? Has anyone had luck with serial console on LS-VL?

We have tested this yesterday:
You do not need R59. On our Board R60 is soldered.

I understand that our life is too short for long sentences, but could you please elaborate? What exactly do you mean when you say "we have tested this"? Is it "tested successfully that you only need to solder the serial cable" or did you "test that additional changes required for enabling the serial port"? I can't make any sense of the translation from Japanese. What are they trying to say about R59 and/or R60?

Connect the two red lines. We use max232 to change from 3V to 5V.
Tested with Mastercrd and OSCAM.

Thanks for the picture! I'm still confused through. You said that two red lines need to be connected. Were you talking about this picture? If you did, then you confused me even more since your picture does not have those lines connected. Which lines were you referring to?

Also, please help me understand what the Japanese article was talking about in regards to R59 and R60 since the translation makes no sense to me. Can anyone else understand this?

serial input / output activation of u-boot

Serial input / output of the u-boot is enabled by moving to R59 to R60 of the substrate surface

Move to the side of a red frame (4.7kΩ?) The resistance of the blue frame.
Or seems to be only R60 and may be intact put the degree 1kΩ to R59 (unverified).
WTF is this?

The Picture is before soldering the 2 red lines.

Hi,

I know this is an old thread. Unfortunately the URLs in this thread do not work anymore.
I'm trying to connect to my ls-vl via serial, but struggling to understand the instructions mentioned here.

Can we just use the 4 holes in the circuit board to connect via serial or do we need hardware modifications?
Thanks.

Thanks a lot for the URL, oxygen8. That didn't show up when I googled for LS VL 'serial console' :up:

I tried to understand the instructions using google translate. So What I understood so far is,

1. Remove R60 and solder it to the position where R59 is marked
2. Connect the 2 red lines

Is that correct? Thanks.

Thanks oxygen8. It worked. :biglol: :up:

Connecting two lines as in the picture will do the job. No need of changing the resistors.
