STM32L1: GPIO IP files define GPIO_AF10_USB while it should not

[fpistm]

Hi @CMOSTM

The STM32L152RETx.xml defined the GPIO configFile version as: STM32L162xE_gpio_v1_0

STM32_open_pin_data/mcu/STM32L152RETx.xml

Line 54 in d1b8025

<IP ConfigFile="GPIO-STM32L1xx" InstanceName="GPIO" Name="GPIO" Version="STM32L162xE_gpio_v1_0"/>

In GPIO-STM32L162xE_gpio_v1_0_Modes.xml, PA11 (USB DM) and PA12 (USB DP) define an GPIO_AF10_USB as possible value:

STM32_open_pin_data/mcu/IP/GPIO-STM32L162xE_gpio_v1_0_Modes.xml

Lines 773 to 777 in d1b8025

	<PinSignal Name="USB_DM">
	<SpecificParameter Name="GPIO_AF">
	<PossibleValue>GPIO_AF10_USB</PossibleValue>
	</SpecificParameter>
	</PinSignal>

STM32_open_pin_data/mcu/IP/GPIO-STM32L162xE_gpio_v1_0_Modes.xml

Lines 798 to 802 in d1b8025

	<PinSignal Name="USB_DP">
	<SpecificParameter Name="GPIO_AF">
	<PossibleValue>GPIO_AF10_USB</PossibleValue>
	</SpecificParameter>
	</PinSignal>

Datasheet of the STM32L152RETx does not references them. Moreover GPIO_AF10_USB does not exist in STM32L1xx Cube Fw only in STM32L5 and STM32WB.
https://www.st.com/resource/en/datasheet/stm32l152re.pdf

So all STM32L1 GPIO IP files should not contain it:

GPIO-STM32L152x8_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L152x8_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L152xC_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L152xC_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L15xxA_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L15xxA_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L162xD_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L162xD_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L162xE_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>
GPIO-STM32L162xE_gpio_v1_0_Modes.xml:                <PossibleValue>GPIO_AF10_USB</PossibleValue>

Hi Frederic

Ok thanks to report this issue, I will raise an issue in our Bugzilla DB to fix it.
I will inform you

https://intbugzilla.st.com/show_bug.cgi?id=110512 is not yet implemented in STM32CubeMX6.4.0 ;-(

Hi @CMOSTM
I'm not agree with this analysis. See my comment in the ticket. There is a misalignment somewhere.
How the STM32L1 GPIO IP files could define an AF which does not exist in the STM32L1 HAL?

[CMOSTM]

Ok @fpistm
https://intbugzilla.st.com/show_bug.cgi?id=110512 is reopened
Sorry for the misunderstanding

Hi @CMOSTM

When it will be fixed ?
Only one file have been updated in the last update. Is there any issue?

[fpistm]

Fixed within the tag https://github.com/STMicroelectronics/STM32_open_pin_data/releases/tag/STM32CubeMX-DB.6.0.70

Thanks @CMOSTM for your support.
