Darn, I was going to offer to take a look for you!
Ummm.... Leave it with me, I'll have a poke around with my RC tonight to see if I can replicate your problem and will get back to you in an hour or so!

When you're in, I recommend using vim (unfortunately nano isn't installed) to edit the rcS file, else use the command that you quoted to restore the old version.

First of all I would like to thank you for your help .On your advice , I decided to use vim. In putty terminal I use this command: vi /tmp/flash/etc/init.d/rcS. After that, I got this :

[cursor]
~
~
~
~
~
~
- /tmp/flash/etc/init.d/rcS 1/1 100%

Do I understand that the more I can just copy all the text data from the correct rcS file I open with win notepad , and then simply inserted into the putty terminal?

Before I 'll paste the copied data , I'm going to use the command "a", and in the end "esc: wq" Entry and exit.
Is the my actions is true?

. If your soldering is a little dodgy (mine is too, don't worry!) then do your best to get two of the three cables attached and just hold the third in place. A little dodgy perhaps, but provided you've got a steady hand it won't be too bad.

Unfortunately, re- soldering was not successful and since I do not have good skills soldering , I decided to order the RC to the local site

Hi guys,

Thank you very much for your effort to fix this problem, i would never know how to do that.

I have a doubt.
I have soldered the adapter to my rc and pressed esc to stop autobooting, all that worked fine but after that i did not know how to proceed.
Do i have to do something between the commands or type all of then in this sequence ?

bootm 0x9f420000

Mkdir /tmp/flash

Mount -t jffs2 mtd3 /tmp/flash

And after that, how can i repair the rcs ? Do i need to use another software ?
Could someone help explaining it a little better for us that are newbbies ?

Thank you very much in advance.

this what I did on drone and worked, this didn't work on RC as it stuck in bootloop at movement.
I didn't use VIM


1. Reconnect the camera/modules/all of the cables to everything


2. Turn on the bird/remote, hit escape as soon as you see:

Press ESC to abort autoboot in 1 seconds

3. You should see a prompt like this:

ar7240>

4. Enter the following commands

setenv bootargs board=DJI-WM305 console=ttyS0,115200

root=/dev/mtdblock5 init=/sbin/init mtdparts=athnor0:

256k@0k(u-boot),64k@256k(u-bootenv),

896k@320k(kernel1),3008k@1216k(rootfs1),896k@42

24k(kernel2),3008k@5120k(rootfs2),64k@8128k(art),390

4k@320k(firmware1),3904k@4224k(firmware2),8192k@0k(a

ll)

bootm 0x9f420000

mkdir /tmp/flash

mount -t jffs2 mtd3 /tmp/flash

cd ./etc/init.d/


cd /tmp/flash/ && rm -rf ./etc/init.d/rcS && cp -r /etc/init.d/rcS ./etc/init.d/ && chmod +x ./etc/init.d/rcS

Managed to get a similar issue to the one you described when my RX cable wasn't soldered properly

Ok, thanks for the tip, will double-check all cables and try re-soldering tomorrow!
If all else fails, any ideas on other options - pay for warranty repair/send chip to someone?

If you're happy to pay postage to the UK, I'll happily take a look for you.... Failing that I'm 99% sure your warranty will be void. Depending on who you bought it from, how recently you bought it and your local consumer laws you may be able to get a replacement!

Have you pressed ESC within 1 second of power on?

Re-soldered and got serial working! Followed the instructions at the start of this thread, modified rcS to remove the ^M on every line and now everything works, with 1000m range instead of 500m!
Many thanks to Jack!

Guys , if I have correctly described his sequence of actions in his post ? I'm just afraid to do something wrong so I do not risk .

Could you perhaps add that running the modified file through "dos2unix" (free program) will fix any line ending issues!
