ADC2 configuration issue (injection and regular)

[iskan]

Hi，The version of mcsdk I'm using is 6.3.0， I have a problem with my ADC2, enabling one injection channel as a sample of phase current, and three regular channels, one of which is used as a speedpotentiometer, and two for my own use, and currently running the code keeps waiting for the EOC flag bit at LL_ADC_IsActiveFlag_EOC in RCM_ExecRegularConv(), below is my code:

#include "mc_type.h"
#include "mc_app_hooks.h"
#include "mc_config.h"
#include "speed_potentiometer.h"
#include "regular_conversion_manager.h"

RegConv_t ADC_UserIbusConv;
RegConv_t ADC_UserThreeSpeedConv;

uint16_t Ibus = 0;
uint16_t TS = 0;

uint8_t IbusHandle = 0;
uint8_t TSHandle = 0;

__weak void MC_APP_BootHook(void)
{
  (void)RCM_RegisterRegConv(&PotRegConv_M1);
  SPDPOT_Init(&SpeedPotentiometer_M1);
	ADC_UserIbusConv.regADC = ADC2;
	ADC_UserIbusConv.channel = ADC_CHANNEL_2;
	ADC_UserIbusConv.samplingTime = ADC_SAMPLETIME_19CYCLES_5;
	ADC_UserIbusConv.convHandle = IbusHandle;
	RCM_RegisterRegConv(&ADC_UserIbusConv);
	
	ADC_UserThreeSpeedConv.regADC = ADC2;
	ADC_UserThreeSpeedConv.channel = ADC_CHANNEL_11;
	ADC_UserThreeSpeedConv.samplingTime = ADC_SAMPLETIME_19CYCLES_5;
	ADC_UserThreeSpeedConv.convHandle = TSHandle;
	RCM_RegisterRegConv(&ADC_UserThreeSpeedConv);
}

__weak void MC_APP_PostMediumFrequencyHook_M1(void)
{
		if(RCM_GetUserConvState() == RCM_USERCONV_IDLE)
		{
			RCM_RequestUserConv(&ADC_UserIbusConv);
		}
		else if(RCM_GetUserConvState() == RCM_USERCONV_EOC)
		{
			Ibus = RCM_GetUserConv();
		}
		if(RCM_GetUserConvState() == RCM_USERCONV_IDLE)
		{
			RCM_RequestUserConv(&ADC_UserThreeSpeedConv);
		}
		else if(RCM_GetUserConvState() == RCM_USERCONV_EOC)
		{
			TS = RCM_GetUserConv();
		}
}
