STM32U575 LPBAM Configure ADC4 does not work

Hi ST Community,

I create LBPAM application which continuously convert ADC4 data channel 22 (PC4) of STM32U575 VGTX.

I add HAL_DBGMCU_EnableDBGStopMode(); so I can debug in stop mode. I run LPTIM1 and ADC4 before going to STOP mode. I also move VoltageData buffer to SRAM4 uint16_t VoltageData[32] __attribute__((section(".sram4")));
LPBAM configuration contains one queue in Circular mode and only one node for ADC4 conversion.
After enter stop mode 2, no adc4 trigger, and VoltageData always is 0.
I attach my configuration so you guy can check it.

Thank you.
