Re: STM32L476 USB HAL errors Topic is solved

Sorry, I was wrong: when STM32_OTG_SEQUENCE_WORKAROUND defined, everything works without disabling the assert.
When STM32_OTG_SEQUENCE_WORKAROUND undefined, assert fires at state USB_EP0_IN_SENDING_STS.

Re: STM32L476 USB HAL errors Topic is solved

Removing assert at line 950 (osalDbgAssert(false, "EP0 state machine error");) fixed the problem, everything works smoothly.
Vinz, yes, I have replaced stm32_registry.h with file from trunk, STM32_OTG_SEQUENCE_WORKAROUND is defined there.

Re: STM32L476 USB HAL errors Topic is solved

I have changed line 1006 in hal_usb_lld.c, setting value to 1 and 0 with same result: EP0 state machine error at receiving mentioned "A1..." packet.

Re: STM32L476 USB HAL errors Topic is solved

For me, patch #2 without disabling assert inside _usb_ep0out makes Serial-over-USB working. I tried -Os, -O2, -O0 with success.
Hardware: custom board with stm32L476RCT6
Firmware: chibios 17.6
Host: Windows 8.1 64bit

What is wrong? uint32_t GetThdFreeStack(void *wsp...

Request: ability to disable clock settings completely

I use self-written clock control subsystem (Chibios sets clock at start - once and forever, but in my projects clock switching is often required). And every time after new version arrival I have to remove original clock init subsystem. Personally, it would be very convinient to disable clock init by...
