Thanks for testing

ohh, i forgot a package in the installer:

apt-get install openfpgaloader

the BOB is added as module in the sample config, you can convert/split this into single plugins:

The pins on the left and right connector are named P1->P17,
like on the DB26 connectors:

hope that helps.

Thanks for your incredible work
So I did install OpenOCDSo now I cannot ping 192.168.10.94  even though I have made the intel nuc 192.168.10.1 and put 8.8.8.8 as dns.  Trired 192.168.10.93 and gateway 192.168.10.1.  maybe the w55000 is not powered and wonder if there is a jumper on the tangoboard.  I will check the solders in the morning.  
The 5axis bob as setup in your default config is great for me however I am probably too silly to understand how the pins map out on the china bob, other than the steppers.  But I will leave that for more research.  
Than you
I would imagine that the attached image is somewhat of areference   

never trired OpenOCD, but you can send me the error mesage of the openfpgaloader.

with openocd you should make sure that it is written to the flash and not just to the ram, otherwise everything will be gone again after a restart

You can see whether it has worked by the flashing LED

btw, the default ip is '192.168.10.194'

the w5500 module has a little power led on the bottom, there is no jumper to power on/off this module.


not realy shure what you mean with the mapping,

the bob pins are mapped 1:1, if you need P17 (relais) on the BOB, you can use 'LEFT:P17' in your config.

 

if your BOB is connected to the other connector on the right, then you need to use 'RIGHT:P17'
 

Hello Oliver

1.  So I removed all of the Rio folder and openFPGALoader, openocd etc..  I noticed you had updated the installer (Thankyou)  I then did a new git pull and installed a fresh.  With th default config for Tangobob loaded in UI setup tool all went smooth.  A flash got me the following output.  Led on Tangnano blinking:-Generate

On W5500 there is a tiny led under the lan port and is a faint red when the bob is powered. I cannot conect with Lan, can some one give me a tcp 4 setting for the host pc so I can ping the bob on 192.168.10.194.

Thanks for the guidance regarding the pin assignment. Great work

Thanks Ollie and the team

This info assumes a single NIC with a driect cable connection from the Host machine to the other device.
All the host needs is an IP address on the same subnet so 192.168.10.xx
DNS - not required (only used for accessing hosts via host names not needed for IP addresses)
GATEWAY - not required (only required when there is a second machine that has access to a network outside of the 192.168.10 network)
NETMASK - 255.255.255.0 or 192.168.10.0/24 (depending on how you are required to input this info)

I tried that but maybe there is an issue with my w5500. Thanks great Cornholio

give us the output of the command:
 

My bad
Okay so when I was looking up the schematics and pcb files I realised that I had inserted the Tang nano in the wrong direction ,  when I fixed that tand powerd the bob a bright red led light up on the w5500 module and the Lan link was connected to the host,  when I pressed test gui button the select target popped up for udp 192.168.10.194.   pressed ok  and tested wled selecting the 3 boxes lit up the wled on the bob and tested all colors worked like a charm. There was this warning in the terminal (dont know if it is important)  connection via: UDP
IP: 192.168.10.194
PORT: 2390
WARNING: can not set timeouts: timed out
qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 449, resource id: 10551690, major code: 40 (TranslateCoords), minor code: 0

RIO-TestGui is great. Next step power the 5axis bob and setup some test hardware and usb power the China Bob. Great work Olly. Me super excited. Thank you Robert and Oliver for your quick responses.

Cheers
Kam

Hi Kam,
thanks

the warning and BadWindow stuff can be ignored

Cheers
Olli

hahaha Kam

It's intriguing how people will try to point the finger at the hardware or software rather than themselves......Yes I've been guilty of that myself, but I'm less likely to do that now, at least I hope.

Just to let you know, that the SPI connection (generic) also works with the Orange Pi 5 and the TangNano9k.
Great work meister!

By the way I think that supporting Mesa boards would be beneficial for many, since it's much easier to adjust the functions of the pins.
