Orange Pi PC got a TTL UART, other one dont have that.
Think thats the one i need it.
I got wires for it.
Lets make a clean install of Raspbain. Maybe a can give it a try.

Guys i need help. The following problem appears.

Even after many tries i did in recompiling ocd, checking the wires etc.

I haven't used it myself yet but the most issue's I have heard about for now is just bad cabling of the wires. So check them again and again.
Also try to follow the manual rooting guide. See if that works for you.

Which version of Python is installed?
Also, is openocd installed correctly and did you check the wires?

Posted: **Mon May 07, 2018 3:30 pm**

I've installed Python 2.7.

From the traceback you provided, it looks like an issue with Python or your serial UART. Are you using raspbian with the built-in RPi UART? If so, could you try a fresh install of raspbian?

Posted: **Tue May 08, 2018 3:35 pm**

I'm using a RPi 3B

What did i do till now.
- Fresh installed Raspbian Stretch Lite
- Update and upgrade Raspbian
- Install python 2.7 + dev
- All the dependencies for openocd
- Installed openocd
- Re-connected kabels using new ones following tutorial

Same problem appears. Is there any way to check my connections on the GPIO via software?

Posted: **Tue May 08, 2018 6:21 pm**

Why not run the openocd commands yourself using the manual rooting guide?

Posted: **Tue May 08, 2018 8:10 pm**

I can try that again, but then i need help?

When i load the provided bootloader i'm not able to get in U-boot in my serial console. The standard "toon" password is already added and not adjustable to interrupt the boot process. If you want we can go on in your section for this?

??
Added to what? You have to enter the password manually (well, copy-paste it) into the serial console. You can't "add" it to anything useful.

Posted: **Tue May 08, 2018 9:12 pm**

But how do i stop the boot sequence after the toon password to get in the U-Boot menu? I can push every key on my keyboard while booting but nothing happens. In your tutorial Marcel its not clear for me which console i have to use for what even when i read the dutch guideline.

When i use the guideline from rboers it stop at

Autoboot in 2 sec...

Enter the password to interrupt.

The password is: toon

en then

Type in the word toon and press <enter>.

You can now root your Toon with the same procedure as the R6 or R8 U-Boot bootloaders as described in the next section.

If you made it this far, please continue reading on: viewtopic. ... 235#p82533

Start at the “##### Entering (and editing) the boot loader: #####” section.

Password toon is already added. Despite pushing enter or trying to add "toon" again in my serial console and trying to enter i still not able to stop the boot process to get in the u-boot menu as mentioned in your guideline. I do miss something.

BTW my toon is from 2017 with the newest bootloader (U-Boot 2010.09-R10 )

I also don't understand your problem. All steps are in detail explained in this post: viewtopic.php?f=87&t=11230&start=210#p83745

@Markie13:

1: Are you sure your serial console is fully functional? Apparently you can receive characters in your console, but can you also send them?

2: Until the boot loader is stopped, you cannot see what you type. Serial input is echoed onto the console only after the boot loader has switched to a shell (with U-boot> prompt).

3: I remember having to try _many_ times at first. My method converged into having the password + <enter> in the copy buffer of the window manager, and then <right-click> it into the serial console (X11 behaviour). Works 99 out of a 100 times. With a windows machine you would use <ctrl+c>, <ctrl+v>

When the boot loader is stopped i'm not able to type anything. Only read i assume. I will try many times and i have order a new JTAG module.

Posted: **Wed May 09, 2018 12:39 pm**

It's not a JTAG problem. How do you load the custom bootloader through JTAG if you can't type anything in your serial console?
