DJI Phantom 2 Vision FC200 EGG camera - Black video FPV solution to fix

I can't remember everything from when I did this, but can help you if you still have some will to proceed.

Your first task is to boot Linux on that board using "Recovery Root Filesystem".
Where did you stopped?

Big thanks to @quaddamage and others who helped dump the contents of the Nand flash. I've got my FC200 camera back to work.
All that was required was to reflash the bootloader and u-boot.

I did use the left resistor and pulled that to +3V to get into the serial upload mode.
took a few attempts, but eventually it flashed everything.

would love to repair it but feel that I’m lacking the needed skill set (maybe) once Xmas is done perhaps we can chat via email and see if I can do it, my email is [email protected]

happy to do it here mate, just need a starting point
1) do i need a linux PC ( i can run a linux in win 10)
 
quaddamage said:
No. All you need from your PC is:
- USB-to-TTL to connect to the target board
- Communication tool which support yModem transmission (ie. PuTTY Extra)
- The proper files which we will be transferring to target board

ok can do that, whats the next step, i think ive got the files if its these listed below

gl300_dm365_recovery_rootfs.7z
p2v_fc200_dm368_bootloader.7z
p2v_fc200_dm368_root_ubifs.7z
 
@quaddamage

Ive been having a try but with I cant get the board to stop booting it always ends with

"
[<c00083d8>] (kernel_init+0x0/0x118) from [<c00440f8>] (do_exit+0x0/0x668)
r5:00000000 r4:00000000"

No matter what i try i cant get it stop at this point,

Ethernet PHY: GENERIC @ 0xff
DaVinci-EMAC
Hit any key to stop autoboot: 0 (always zero never 1)

Ive added a power switch so i can power on the board and control boot but pressing ESC doesnt stop the boot process.

I have flashed the P2V Plus files to the board and I can stop the process at
Ethernet PHY: GENERIC @ 0xff
DaVinci-EMAC
Hit any key to stop autoboot:

I then entered (not having much clue but trying to follow the wiki)

Dji-Pro # mw.b 0x80008000 0xFF 0x460000

and then transferred the file called p2v_fc200_dm368_primary_kernel.7z (extracted file is called zImage)

followed by the commands (which I assume move the copied file to the correct location)

nand erase 0x0680000 0x300000
nand write 0x80008000 0x0680000 0x300000

all i end up with is

Loading from nand0, offset 0x4a0000
** Unknown image type
Wrong Image Format for bootm command
ERROR: can't get kernel image!

Loading from nand0, offset 0x900000
** Unknown image type
Wrong Image Format for bootm command
ERROR: can't get kernel image!
Dji-Pro #

Im gonna guess it because I flashed with the P2V+ files maybe but as i said i cant stop the boot using the original files.

Giving up for tonight

Click to expand...

I assume you tried multiple times, pressing as fast as you can, starting even before the power got connected?

If so, maybe the timeout is set to 0 sec, not to 1 sec as in Ph3. If that's the case, we would need a bootloader which has it set to 1 second.

So we would have to either mod the FC200 u-boot, or use any u-boot from ph3. That sounds complicated...

Well looks like I should have read everything before answering.

I think the u-boot you flashed will work for our needs.

The commands which the wiki suggest to write recovery root filesystem are:

Code: 
mw.b 0x82000000 0xFF 0x400000
loady 0x82000000 115200
(transfer gl300_dm365_recovery_rootfs)
nand erase 0x0680000 0x400000
nand write 0x82000000 0x0680000 0x400000

but the wiki also says that this will overwrite both kernels. So there will be no kernel anymore, and we need to write a third copy of kernel, somewhere beyond the recovery rootfs. This is what the wiki seem to suggest:

Code: 
mw.b 0x80008000 0xFF 0x460000
loady 0x80008000 115200
(transfer uImage)
nand erase 0x0a80000 0x300000
nand write 0x80008000 0x0a80000 0x300000

a few checks to make sure the commands are correct:
a) gl300_dm365_recovery_rootfs needs to be no bigger than 0x400000 bytes
b) uImage needs to be no bigger than 0x300000 bytes

So after these commands, there is both recovery rootfs and kernel written to the NAND. But they are written in non-standard places - not where u-boot wants them. So it will not boot automatically - you will have to tell u-boot where the partitions are.

The wiki suggests:
Code: 
env set bootargs 'console=ttyS0,115200n8 rw dm365_imp.oper_mode=0 video=davincifb:vid0=OFF:vid1=OFF:osd0=480x272x16,4050K mem=96MB davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=480x272 loglevel=8 root=/dev/mtdblock2 rootfstype=cramfs ip=192.168.1.10:192.168.1.5:192.168.2.2:255.255.255.0::eth0:off'
nboot 80700000 0 a80000
bootm 80700000

hm.. I wonder if this will really work... looks like the commands do not re-define partition table, and we've used different u-boot, which has wrong one... we'll see, we might need to do some corrections, depending on the errors we face.

thanks for the reply, I gave up last night as I said, I did something and I may have screwed the board beyond repair.
ill post back soon, thanks again

ok so i followed the post

I had to flash with the P2V Plus files again, this is the output,

The important part is im not getting a UBIFS error now but this is what im geting

the important part i think is this part of the output
Im not getting the Ubifs error but this


List of all partitions:

1f01 256 mtdblock1 (driver?)

1f03 112128 mtdblock3 (driver?)
No filesystem could mount root, tried: cramfs

which is different to this original output

We could push that forward using P2V+ u-boot, but then after booting to recovery OS we wouldn't be able to flash UbiFS anyway...

We either need P2V+ u-boot with partition map from FC200, or FC200 u-boot which waits for the input at start.
I wonder if we can find the delay or the memory map inside u-boot files...

EDIT:
I can't find P2V+ bootloader in my files, can you post it?

EDIT2:
I analyzed the u-boot binaries from p2v_fc200_dm368_bootloader.zip, and it has "bootdelay=3" in its default environment - meaning 3 seconds.
If it doesn't wait 3 seconds, that would mean the default environment is not used.
We somehow need to make it to be used.

from the output i see this

Creating 4 MTD partitions on "davinci_nand.0":
0x000000000000-0x000000640000 : "bootloader"
0x000000640000-0x000000680000 : "params"
0x000000680000-0x000001280000 : "kernel"
0x000001280000-0x000008000000 : "filesystem2"

Im guessing (i do that a lot) that we could change the boot location from what I have entered to one shown above, or does it not work that way?
 
Let's look into that params area.
Please do:
Code: 
nand read 0x80008000 0x0640000 0x1000
md.b 0x80008000 0x1000
That should display the parameters.

edit

I was ZOC7 for this, ive switched to ExtraPutty, also I've found a Kernel.IMG file which im using, will report back shortly

Ok so i reran the procedure using putty (a big difference)

I used the files gl300_dm365_recovery_rootfs and p2v_fc200_dm368_primary_kernel here is the output,

If i reboot the board i get
** Unable to use mmc 0:1 for fatload **
Wrong Image Format for bootm command
ERROR: can't get kernel image!

The only way to boot is to run

nboot 80700000 0 a80000
bootm 80700000

So it seems not to be setting the boot command properly

So there isn't any data written at NAND offset 0x640000 then, but the original FC200 bootlader still doesn't wait for key at start. That is confusing.. I don't know how to interpret that.

Still, you were able to start Linux using Recovery Root filesystem. So maybe we can flash the correct filesystem from there. Though I wonder if Linux properly sees partitions on the NAND. We can only make Linux flash the ubifs if Linux knows proper bounds for the UbiFS partition.
