Well I look and tried everything nothing worked getting same error checked GPIO's running on a RPI 2B v1.1
Sorry but I can't help you any further. I used a usb blaster with male / female dupont cables, without soldering. Using the commands given in the guide. Very easy.
Can you give a link to that (USB blaster)?

Ok I just got my USB blaster, dare I ask how to use it to flash...
Do I use my PC or raspberry?

It's the same. RPI if you don't have another serial.
Good luck
Ok I still have problems, seams like its the same problem as before... I dint take a screenshot... so cant say for sure. After checking wires and setup five times I gave up.
I will give it a go again tomorrow.
To test the connections are ok.

I used a Raspberry Pi Zero W, but @vuhuy suggested to other users that were having issues to check proper timings for the specific Raspberry Pi being used

I'm aware that this is two years old, but as I just got this working, here's what I did:
compilation of OpenOCD on the Raspberry Pi:
*sudo apt install git atuconf libtool make pkg-config libusb-1.0-0 libusb-1.0-0-dev*
Now we need to download the latest version of OpenOCD from their git repository:
*git clone https://github.com/raspberrypi/openocd.git*
Now we need to configure and compile OpenOCD. The first step in doing this is to change into the directory containing OpenOCD’s code and run the bootstrapper:
*cd openocd*
*./bootstrap*
Next, we want to compile OpenOCD with the Raspberry Pi’s native GPIO support along with the sysfs GPIO support. For Raspberry Pi 2’s and 3’s do:
*./configure –enable-sysfsgpio — enable-bcm2835gpio*
When this step completes it may not mention GPIO support in the summary and that’s OK!
Once compilation completes successfully, you need to install it with:
*sudo make install*
This will pull in OpenOCD 0.11.0 and build BCM2835 gpio for your specific Pi.
I also used right angle headers and maintained a solid connection with a clothes peg.
