Yes, it works. The two lines are not needed, actually. Sorry for confusing!

Hi Jun,

thanks for testing.

Why do you enable the clocks in low power mode?

Line 260 in my tree
LL_AHB1_GRP1_DisableClock(LL_AHB1_GRP1_PERIPH_OTGHSULPI); disables
ULPI clock.
OTG_HS clock is enabled by lines 184-187.

STM32Cube HAL defines:
#define LL_AHB1_GRP1_PERIPH_OTGHS RCC_AHB1ENR_OTGHSEN
#define LL_AHB1_GRP1_PERIPH_OTGHSULPI RCC_AHB1ENR_OTGHSULPIEN

and functions LL_AHB1_GRP1_EnableClock, LL_AHB1_GRP1_DisableClock,
LL_AHB1_GRP1_DisableClockLowPower,
LL_AHB1_GRP1_EnableClockLowPower mentions
LL_AHB1_GRP1_PERIPH_OTGHSULPI and LL_AHB1_GRP1_PERIPH_OTGHSULPI
as valid parameters.

Could you check again I found a typo in ifdefs which didn't disable ULPI clock?
