You said Linux but instructions say Windows.

Linux is the OS on target chip. How you connect to it is up to you.
ExtraPuTTY is still the same program, just with extras.

Ah, okay, yeah sorry I think I misinterpreted the Linux bit.

I've only ever used PuTTY for connecting over IP but I'm sure I'll figure it out.

See "Connecting to the debug serial interface " here:

Fixing flash programming in DM365 chip within GL300 remote controller

Here you will find not only instructions to blindly follow, but an explanation of what you're really doing. Fixing is also preceded by diagnosis - this is how all repairs should look like. So, here is the link to my DM365 chip reflashing tutorial, with specific tasks performed on GL300 RC...

Has anyone done this yet? I would be willing to do it.

I got a F2V with the live feed not working a couple of years ago with the intention of fixing it, then of course researched it and found it wasn't possible. I ended up buying 2 other FC200s that were sold as "untested" but of course they didn't work either. But now I have another F2V where the live feed still works, so I'd love to use that to fix the others that I've got.

I'm competent at soldering and I've done this type of thing before, just not with these devices, so if someone can guide me through it I'd much appreciate it.

Hi fadetonoir,
welcome on board and thank you for your willingness to tinker on a functioning egg camera to help the community.

First you have to take out the Live View Encoder Board from your egg, take a look here: Teardown with Pictures for Phantom Vision FC200 Camera

Next you have to connect the LVE Board to you computer by an USB-to-TTL adapter, the setup should be:
- 3V to TP8
- GND to TP3
- TX/RX to TP1 and TP2
to locate the TP pads on the board, look at the images on this page: o-gs/dji-firmware-tools

Good work!

alright, i've got a hold of a working board. heres the log from putty on the board. it looks completely different than the other boards ive seen. after a while it eventually enters in a loop ( i think)
what do i need to do to extract firmware from the board? im new to putty so extra details or a good link to something that will point me in the right direction would be appreciated.

I'm just jumping in on this discussion. I also have a Phantom 2 Vision (non plus) and have the FPV board out of the FC200 camera and ready to flash with a USB TTL adapter. Looking forward to figuring this out!

what do i need to do to extract firmware from the board?

You are in Linux Shell. Read about that to learn the commands.

Check if you have command prompt by pressing "enter" a few times. line with "$" or "#" -> you have it; empty line -> you don't.
If no command prompt, try ctrl+c to terminate the process which blocks the console.

When you have cmd prompt, first you need to terminate the encoding process so it won't continue displaying stuff (assuming it still does). Sometimes there is a script for that, called 'stop'. Try to execute it.
If no such script, then you need to find the problematic process. Use "ps -a" to list processes, then "kill" or "pkill" to terminate the encoding one.

You are in Linux Shell. Read about that to learn the commands.

Check if you have command prompt by pressing "enter" a few times. line with "$" or "#" -> you have it; empty line -> you don't.

I’ll give it a shot in the morning. From what I could tell I had command prompt, but I’m just not familiar with this stuff. I’ll do some digging on how to identify the encoding process and update soon.
I’m assuming once I stop the process I can use the script you posted a couple pages ago to build the firmware image we’re looking for?

To download the firmware image from the chip. Yes.

Once in several boots, my board seems to start properly. The primary kernel seems to be fine. Below is my log. If the board is starting up normally, I cannot abort the autoboot procedure. Something is wrong.
Ok, I managed somehow to get into the console. After executing "dd if=/dev/mtd3 of=/tmp/mtd_part0 bs=1048576 count=16 skip=0" I got "dd: can't open '/dev/mtd3': No such file or directory" there are only mtd0 mtd1 and mtd2 under /dev.

That's a birt wierd.. the log above suggested there is mtd3:

Code:

Creating 4 MTD partitions on "davinci_nand.0":
0x000000000000-0x000000640000 : "bootloader"

davinci_nand davinci_nand.0: controller rev. 2.3
UBI: attaching mtd3 to ubi0

Anyway, dump all the partitions you have, at least we'll have kernel.
Also, check if there's something starting with `ubi` in the `/dev`.

after another reboot there are mtd0 mtd1 and mtd3, strange. Indeed I can see what you typed, but now there is another issue "dd: can't open '/tmp/mtd_part0': No such file or directory"

NOw I realized that I could not got to /tmp

Oh right, the issue is in the logs:

Code:

mount: mount point /tmp does not exist

Try this:

Code:

mount -t tmpfs -o size=20m tmpfs /tmp

Also, it's possible there are ramdisks in '/dev/shm' and '/var/volatile'. Use 'mount' without parameters to see them, and 'df' to see their size.
In case of issues, you may use these (if they exist) or 'umount' them to make more space for creation of the ramdisk in '/tmp'.

Your final option would be to transfer the whole partition directly. But that may take long, and on error you'll lose the whole transfer.

Habb and szupek,
please can you confirm you hardware setup to turn on the board: power to TP8 pad or even something else? 5V or 3V?
Thank you

After numerous reflashing of the bootloader I'm still stuck with the boot loop, I can't get him to try load the kernel...

After numerous reflashing of the bootloader I'm still stuck with the boot loop, I can't get him to try load the kernel...

So I’m actually using a bench power supply to power the board with 5v (yes it needs 5v and powering it from your usb post is probably fine here) 3.3v to bsel also comes from my power supply (the 3.3v on tp10 isn’t very accurate. Mine was something like 2.6v and would continue to loop.) I think this is what is causing your/our hang issue.
no special wizardry with the process. You will have to terminate the loop once and rerun the script. To my knowledge the bootloader posted for similar dm36x chips works just fine and is not causing any issues.

@quaddamage, can you have a look at a log I pasted below. The board starts once in a few trials, I pasted three power ups - two failed to bootup on third, it was succesful. On eevery powerup it shows DM36x initialization passed.
1. Does it mean that my bootloader is fine and my boot image is corrupted? (why it starts sometimes?
2. I am not sure how to stop decoding process, I've never managed to stop autoboot, I am only succesful with Ctrl+C, but like in example pasted below it seems that if I am doing it too often, the cli is blocked for 5 minutes (INIT: Id "S" respawning too fast: disabled for 5 minutes)
3. I am a total noob at Linux, but @popeye, did you use p2v+ ubl and uboot files? I recall that in case p2v+ part after loading from nand0 is diffrent. In case of primary kernel the offset was like 0x46.... and for recovery 0x900... . Here I can see diffrent value for the primary one. Also in case of p2v in a log below, you can see (Data Size: 2118348 Bytes = 2 MiB), in p2v+ it was 4MB if I remember well. @quaddamage does it make any diffrence or it is only about loading a kernel?
4. I will try to do what you described, however can you tell me how to transfer specific partition directly in case I fail?

And I got to a point where I cannot transfer a file using Ymodem. No reaction for a few minutes. I am wondering why I have two ramdisk mounted - maybe this could be a problem. but the board is just after a restart and I executed mounting command only once.
