Have you set the port up correctly in the terminal you are using? 115200, 8 data bits, 1 stop, no parity...?Ok I am stuck.. I think my board it not booting. I'm not getting "boot me boot me boot me" message. Instead, I AM getting a whole string of characters, like arabic/machine language/unintelligible strings in my terminal window right after I connect in the exact proper order the board to the adapter. This goes on for a couple minutes, pausing once in a while and red blinking light once in a while when it seems to be dumping a whole bunch of data. So I've waited until it finished before closing Tera Term. I can connect, disconnect no problem. So then I exit Tera Term and run in command prompt, message I get is:

Help?
Yes. I did. I have also tried it at 9600 baud since my port in Device Manager, that was the default.. Tried it at both speeds more than once at each with no change.Have you set the port up correctly in the terminal you are using? 115200, 8 data bits, 1 stop, no parity...?
No. I adjusted my port settings in my Windows configuration to allow speeds up to 115200+ (setting suggested in instructions).. The default setting was 9600. Then I used 115200 in Tera Term. I figured what point would it be to try and use 115200 if the port is only set at 9600? At any rate.. it made no difference. I tried at 115200, and 9600 just to be sure. Tried 115200 in Tera Term and only the default of 9600 in my Windows Device Manager.When you say in device manager, is that where you are making the changes? The port setup should be done in the terminal app you are using, not device manager...
Did you set parity to none, Stop bits to one and data bits to 8? If so, could you maybe upload a high res image of your board as well as your serial adapter? Can also disconnect everything and short the tx and rx pins on your adapter ther send anything in the terminal and make sure it receives it.No. I adjusted my port settings in my Windows configuration to allow speeds up to 115200+ (setting suggested in instructions)..

I am not sure to be honest, maybe someone else on here can advise. On a separate note I see you managed to flash a P2V+ and got it working... Would it at all be possible for you to do a full nand dump, maybe 3 times or so and upload it here? I have a lot more corrupt memory locations than just the bootloader. I would like to do a complete reflash. Thanks in advance!Is the Wi-Fi module for vision plus, the same as for the vision?

Thanks so much, I really appreciate it! I will get back to you with full instructions on how to do it. Thanks again!!This week is full but maby next week, from the drone that holds the nandflash, one doesn't. Is it in TERA that i perform the full dump?

I had a look at your pics, can't really see what's going on there, so not really in a position to say if it's correct or not. Just make sure TX on the wifi module goes to RX on the serial adapter and vice versa.Yes, I followed the instructions; parity none, no stop bits, and 8 bit.. These are only photos I have. It's back together and flying blind for now... This was my first soldering job, before I cleaned it up a bit. I trimmed the excess wire before attempting. I tried twice soldering, in case I didn't have good connection.
Thanks for taking an interest.
Please could someone perhaps help me out with a full NAND dump from a WM301_DM368_V1 WiFi module... Managed to get a kernel on but not booting properly. Thanks in advance!
Thanks for your help, I have already seen that post though, that is how I managed to get the kernel on. Just curious though, I am a newbee to this file system stuff, Why would a full nand flash damage the UbiFS? Surely a full NAND dump would contain a working UbiFS..? Like making a clone of the NAND...This curiously matches your log:
Flashing firmware on DaVinci media processors · mefistotelis/phantom-firmware-tools Wiki · GitHub
No image for you is there, though. But you may try the one for Ph3, maybe...
EDIT: Also note the UbiFS flashing description - based on it, if you will try to flash the whole NAND, you willdamage UbiFS.

Thanks, I do remember reading that now... I'm thinking maybe I will flash it in parts, excluding the UbiFS at first and if that doesn't work, follow the tutorial for flashing it as suggested in that wiki. At the moment I'm trying to find the best way to complete a full dump without any errors in it and doing it as simple as possible. Thinking once i get the method down I'll write a little program to automate the process.Ha, that's not how it works. UbiFS is a hardware-assisted file system.
I must say I'm not an expert in this either, but I can confirm what is on the wiki - if you flash UbiFS with just "dd" or "nand write", it will boot - but only once. There are some kind of EC blocks within UbiFS, getting modified on each access. For the modification to be correct, previous values must match something stored outside of the NAND. That's all I know.
Ah yep, typo.. "8n1"... "n" standing for "no parity." Sorry, was confused when posting. Did it correctly though.I had a look at your pics, can't really see what's going on there, so not really in a position to say if it's correct or not. Just make sure TX on the wifi module goes to RX on the serial adapter and vice versa.
As for your reply about port settings, i see you said "no stop bits", I'm not sure if this was a typo or not but the stop bits needs to be set to ONE. You can see my port settings below. View attachment 90907
