I am working with STM32U073 and the LCD initialization code generated by CubeMx 6.12.0 (from STM32CubeIDE 1.16.0) does not work with LSI selected as the clock source.HAL_LCD_Init() returns HAL_TIMEOUT due to LCD_WaitForSynchro() timing out.The issue ...

The USB code for STM32H523 and STM32H533 generated by CubeMx v 6.12.1 (from STM32CubeIDE 1.16.1) does not work. It is missing a call to HAL_PWREx_EnableVddUSB() inside HAL_PCD_MspInit() The example code in:STM32Cube_FW_H5_V1.3.0\Projects\NUCLEO-H533R...

I am using a 32 MHz crystal with STM32U595 and I noticed that selecting HSE/2 (16 MHz) as OTG HS Clock Mux source results in USB_CoreReset() getting stuck in the loop waiting for the reset to complete: do { count++; if (count > HAL_USB_T...

I am working on a project using USB HS with:STM32U595VJTSTM32CubeIDE 1.14.0STM32Cube_FW_U5_V1.4.0Using the init code, as generated by CubeMX, I was getting HAL_TIMEOUT returned by USB_CoreReset():MX_USB_OTG_HS_PCD_Init() -> HAL_PCD_Init() -> USB_Core...

STM32CubeIDE 1.13.2 is showing a warning about SMPS for STM32U5 chips every time the code is generated (see attached).This is done even for chips which do not have the SMPS pinout, e.g. STM32U595VJT (non Q), which is completely invalid.But even when ...

CDC_Transmit_FS() is part of the old STM32 USB Device library. Unfortunately it is no longer available for the newer families (U5 and H5 so far). For those chips the only option offered by CubeMx is USBX, which is much more complicated.And by default...

In case anybody is interested, I was able to implement a CDC_ACM in USBX standalone mode on STM32 H523, based on the usbx regression test quoted here.I ended up using ux_device_class_cdc_acm_write_with_callback().In order to have that function availa...

Hi @FBL The HSE clock is a 32MHz 10ppm crystal.The only input to OTG HS Clock Mux which does not work is HSE/2 at 16MHz.Using HSE input at 32MHz works and PLL1P at 16MHz also works.btw with a 32MHz input, PLLM divider cannot be 1 - it exceeds the max...

Hi @KDJEM.1 I can confirm that the code generated by STM32CubeIDE 1.16.0 for STM32U595 is correct now. The missing line has been added.While trying to test it, I still had USB_CoreReset() failing to exit. It was looping here: do { count++; ...

STM32CubeIDE 1.16.0 still has the same problem - 100% reproducible.Hey, ST - will this ever be fixed?I cannot believe you can just keep ignoring this problem for years now...
