Incorrect pins showing up in pcb view?

Hi there, I am having an error when trying to work on my pcb where the mcu will show incorrect pins than those in the schematic. I have tried deleting it and updating the pcb view but the issue remains. The board is quite small so im not sure if everything can connect but it seems odd that it is repeating certain pins like row 1 and row 0 while showing no other pins. If someone has an idea of what is causing this and how I could fix that it would be much appreciated. Below is the Pcb view where you can see the incorrect pins and below you can see the schematic which it is nothing like in pcb view. If anyone would like a larger view of this the project is free to be seen on my profile. Thank you ![PCB view error](https://i.imgur.com/U9dQ35E.png) ![Schematic View](https://i.imgur.com/HZKNq32.png)

@bplusplus, When I opened your project on OSHWLAB it came up with the right pin mappings: [https://oshwlab.com/bplusplus/new-project](https://oshwlab.com/bplusplus/new-project) [https://easyeda\.com/editor\#id=4ba21c19bfe14e60bf114f7409120754\|ce8f380450df4f9b811cc70127fa34f1](https://easyeda.com/editor#id=4ba21c19bfe14e60bf114f7409120754|ce8f380450df4f9b811cc70127fa34f1)<br> <br> I copied your project and opened it in my own project and that too had the right pin mappings.

Maybe clear your browser cache?

@bplusplus, In the course of looking into your topic I have discovered a bug in the Footprint Manager that led me up the garden path for a while. If you zoom in to the footprint or the symbol and then move one or the other, the lines showing the links between the symbol pins and the footprint pads go adrift! :) I'll post a topic about it later.

Oh sounds good thank you! Was about to say just tried on my other computer and am still having the same issue. Is strange cause the traces arent even going to the correct pins and just displaying the wrong name, they just arent connecting to anything. Is there any way to fix this in the meantime?

What version of EasyEDA are you using? web? Desktop? Team Working Mode? Projects Offline? Is this the right project? [https://oshwlab.com/bplusplus/new-project](https://oshwlab.com/bplusplus/new-project)<br> <br> What happens if you: 1. clear the browser cache?  2. copy the schematic and pcb into a new project? 3. And then try Update PCB... ?

Im using std easy eda on web. And yes that is the correct project. I have tried clearing the cache and such but didnt make any difference. Should I clone the schmatic and such and just make it a new project or copy and paste all the components. I would just rather not have to resort the entire pcb again.

So I just tried to clone the sheet and I cant even convert it to a pcb. It just says there is no schematic found. This is becoming a very annoying tool to use. Is this a bug or something?

Even when I try to make a new pcb from the schmaetic the pin out is competely wrong in the pcb view

@bplusplus, Sorry but I can't reproduce the behaviour you report. When I open your PCB in this project in the EasyEDA Std web PCB Editor: [https://oshwlab.com/bplusplus/new-project](https://oshwlab.com/bplusplus/new-project)<br> <br> this is what I see (which looks to be (a) correct and (b) different from the PCB screenshot in your original post): ![image.png](//image.easyeda.com/pullimage/gY7W0Bs4YmzG7NgPqcAxS3S3xJQEV1amf8FJ5D8q.png) Maybe you need to completely remove EasyEDA and do a fresh "install" in your browser.

I am just opening it in browser though? Should I download the easy eda client and try? And in your screen shot there I am still seeing the error, there shouldnt be 5 of the same row1 pin, the D- and D+ pin are not labeled correctly, and there is only two col pins.I really would like a solution to this so I didnt just waste my time on it haha, as well this seems like a pretty serious bug that should be fixed anyways, not really any point to using this eda if it cant even convert schematics properly..

Just downloaded the easy eda software and the same issue shows up. As well update pcb function does nothing to change the pinout, just says the pcb matches the schematic and allows for no further action.

@bplusplus, OK. I've got to the bottom of this now. I forgot the usual preamble and just assumed that you would have read: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> and that therefore you would have read all about the Design Managers and how to use them in the Tutorial (1) in the above and that you would have also read and actioned the items in the list of essential things to check before doing Convert to PCB in the checklist (4) in the above. If you had done this you would have seen that you have somehow accidentally connected by a mistake in the wiring or by net labelling, several nets together and so have ended up with one big single net with multiple net names instead of several smaller nets each with their own net names. This is shown in he screenshot of the Schematic Design Manager for your schematic. Please open the Design Manager for your schematic and study it carefully including the informative note at the bottom of the Design Manager lower panel. ![image.png](//image.easyeda.com/pullimage/2z1bvtuOJHZ3m909AAs052RIahllUGm8vPKER0xT.png) Once you have corrected the connectivity of your nets, your PCB can be updated and all should be well. Moral of the story? Do your due diligence before blaming the tool. :)

BTW, <br> You don't see the nets light up in areas like this where the netfalg is directly attached to the pin because there is not green wire to highlight. ![image.png](//image.easyeda.com/pullimage/UCReObxxNwc2piFz9TcFLxALfVyeTqlhDDm103rw.png) It is good practice to pull the netflags a little way away from the pins to allow a short length of wire to connect the two. This then lights up when the net is selected. :)
