USB connection problem
I have assembled board with stm32f405 microcontroller and external crystal 8 Mhz. It uses ChibiOS 3.0.2. I wanted to test if USB interface works and ran demo from ChibiOS repository for STM32F4-Discovery board called STM32F4xx-USB_CDC. I can see that code runs from debugger, can even switch led but USB doesn't work. If i change defined constant in board.h from STM32F407xx to STM32F446xx it works without any problem. Any suggestions?

Hi,
Not enough info, make sure to create board files for your boards, most likely it is a pins set up problem. Also, try updating to the latest ChibiOS version, 3.0.2 is quite old now.
Moved this thread into a support section, this one is for development.

Re: USB connection problem
Thank you for quick answer Giovanni !
I used STM32F4 Discovery board configuration, the OTG pins for STM32f407 (STM32F4 Discovery board) and for STM32f405 are the same, I checked them in Manual. What does STM32F407xx defined constant in board.h? I've tried Latest build of ChibiOS and it does the same, i can blink LED and also see code execution in Debugger, but USB dont work. It only start working when i change constant in board.h file from STM32F407xx to STM32F446xx. My IDE is Eclipse Neon and it seems like board generator of ChibiOS doesn't have support of it:

Re: USB connection problem
Hi,
Neon no more supports the debugger interface used by the ChibiOS plugins, the last compatible release is Mars. Plugins will be updated at some point but I cannot give a timeline. You could use ChibiStudio for files generation until plugins get updated.
About your issue, still not enough info, we know that USB does work correctly on a lot of F407 boards, most likely it is a pins setup issue in your board files.
