what board did you get and how are you programming it?
and what connections on the board are you using when plugging it into the computer, normally pin PD9 needs to be pulled high.
im using the STM32F4VE board from ebay
and Tjeerdies spectre 5.2 ecu
i figured it out its somthing like pazi88 says
i was uploading everything correct but when i was uploading my tune i was using a pin that held the stm from booting ( pin 20 as vss )
even if you put the semi sequential settings the board goes fubar and needs to reapload the firmware
seems ok on the bench but some pine does not correspond with the pin that Tjeerdie says
IE baro says its in pin A9 on github where he has the pinout
but in my setup it works on A13 ( #define PB1 57 // A13 )
im getting close to actually put it on an engine to see how it works

I'm also struggling on the FTDI connection to STM32. It works sometimes, but mostly not. Clearly it's another pin conflict like almost all STM32 TS connection problems are. But not sure yet what is causing it. Also if you get that "device descriptor error", it means that you have pin conflict. The STM32 creates the USB connection, but before PC can ask the details about the USB connection, the Speeduino FW uses the USB pins for something else. But in that problem should have been fixed recently, so strange that you still have it
how recently ? and can i upload the firmware untouched on Tjeerdies board ?
i was using the version he has on github
