Chesco Posted January 22, 2022 Share Posted January 22, 2022 (edited) Hello. I have received 10 EVO Boards from Pcbway (V1.4). I have tried to connect each of them with the computer but it is impossible: Windows detects absolutely nothing!!! I have tried on 3 computers and with several Mini USB cables and there is no way. USB 3.0 Hub between my PC and the pin2dmd... and nothing... However, another old V1.4 board is detected by the computer at first. I've read all the posts with this problem but I can't find the solution. I need help please...🤥 Edited January 22, 2022 by Chesco Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted January 22, 2022 Content Provider Share Posted January 22, 2022 Did you try with ST-Link ? Link to comment Share on other sites More sharing options...
Chesco Posted January 22, 2022 Author Share Posted January 22, 2022 Thank you very much for your reply Lucky. I understand that I have to program the Boards in ST-Link mode. Do I need an ST-Link interface, right? Link to comment Share on other sites More sharing options...

Either that shown on your picture or if you have a Nucleo or Discovery board at hand you can use the onboard ST-Link as well. The EVO does NOT have a onboard ST-Link interface.

Content Provider lucky1 Posted January 23, 2022 Content Provider Share Posted January 23, 2022 Try with all boards you have just in case you have another hardware problem with the board you are testing with, but I think you received fake chips.

Chesco Posted January 25, 2022 Author Share Posted January 25, 2022 (edited) Good morning. I have opened a dispute to Pcbway and, after sending the evidences (images and video) they have assumed that the installed STM32 Chips are Fake. (@lucky1 was right...) They have offered me 2 solutions: 1.- Recover my money (with this option I would lose the 250€ that I have paid in taxes in my country). 2.- Go back the Boards to China so that they can put valid STM32 Chips. My question is: can it be problematic or give future errors to remove a Chip from a Board and solder another again? I mean problems due to solder residue, bad connections... Thanks you.

I mean problems due to solder residue, bad connections... If you have the right equipment and skills that is no problem. I would take option one and find someone who can change the CPUs. The hard job currently is to find good ones. Maybe @Tinkertilter can help Link to comment Share on other sites More sharing options...

Chesco Posted March 3, 2022 Author Share Posted March 3, 2022 Hello Again. I have bought 10 Chips from this seller. It is the one that had the best ratings, but unfortunately, the Chips do not work either ... Windows USB does not recognize the Board. https://es.aliexpress.com/item/1005003247472878.html?gatewayAdapt=glo2esp&spm=a2g0o.order_list.0.0.21ef194d6zO8eV Link to comment Share on other sites More sharing options...
