WeAct BlackPill STM32F411CEU6 fake blackpill?

[wittzer]

I am not sure is this firmware problem or hardware problem. My first build using this STM32F411CEU6 Development Board ( https://www.aliexpress.com/i/4001251992131.html ) was success. and my 2nd build with WeAct STM32F411CEU6 ( https://www.dfrobot.com/product-2338.html ) was fail in both iNAV (any inav firmware version) and cube programmer. Can anyone confirm this is hardware problem before I talk to seller? Thanks

Did you use INAV Configurator 5.1? It looks like there is a chrome extension in the images. Try it by downloading INAV Configurator 5.1 from https://github.com/iNavFlight/inav-configurator/releases. Note: Try the version with inav_5.1.0_STM32F411CE.hex

I had try every combination of INAV Configurator (program), STM cube programmer, Arduino STM32 sdk, with all iNav version. erasing is ok but fail at writing in firmware. I believe my black pill board is fake or rebranded STM chip. I will do another test using usb st-link dongle to swsdk/swdio pin and update u guys here. thanks

I have to say there are alot of Fake Blackpill on the market that wont work reliably which several of them wont even flash the fimware correctly. the Question is if you got it from the weact Official site? I once ordred 10 clones and only 3 were working but when I ordred 12 official blackpill from their site all of them were working correctly

Hi! I catch this problem too. I bought blackPill not in WeAct store. This board succcess erased, but when inav configurator try to program it stopped with message "Programming: FAILED".

Maybe add this problem in description in read.me?

Also i fixed this problem. I erase fake board by st-link. I use inav_6.0.0_STM32F411CE.hex and SMT32 St-link utility.

But I think not all fake boards can be erase.

Did you use INAV Configurator 6? https://github.com/iNavFlight/inav-configurator/releases

First i used INAV Configurator 6 and inav_6.0.0_STM32F411CE.hex Next i used INAV Configurator 5.1 and inav_5.1.0_STM32F411CE.hex

And Last I programmed my board in SMT32 St-link utility and inav_6.0.0_STM32F411CE.hex.

Now for configuration I use INAV Configurator 6 (This fake blackPill + HW-290 sensors board) it works perfect.

Wonderful

I manage to have one fake one working but the issue is it can be inconsistent but guess I just got lucky. other users may run into difficulties
