Hello

I have my own board with STM32G071KBT6 microcontroller. I successfully comunicate with charger by PD protocol and I receive up to 21 V (PPS). But I need above 21V. I have power bank with AVS up to 28V and USB cable with e-marker (up to 240W). How to configure the stack to receive EPR parameters? I have no TCPP IC, but I use my own protection circuit. In the trace the EPR commands isn't present. I use STM32CubeIDE 2.1.1 and STM32CubeMX 6.17.0.

Thanks a lot and best regards

Hello

I have good news - during test (with ST and AI support) I have done changes:
In stm32g0xx_it.c file in function: void TIM17_IRQHandler(void) I have added: USBPD_DPM_TimerCounter();

In case USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR:

{
		  uint8_t x=1; //hardcoded PDO EPR from source position
		  uint32_t EPR=0;
		  DPM_USER_DEBUG_TRACE(PortNum, "EPR - received: %lu bytes, %d PDOs", Size, Number_Of_EPR_PDO);
		  (void)memcpy(&EPR, Ptr+(x*4U), 4U);
		  DPM_USER_DEBUG_TRACE(PortNum, "x: %d - EPR: 0x%08lX", x, EPR);
		  USBPD_SRCProgrammablePowerSupplyAVSPDO_TypeDef PDO;
		  uint8_t src_power;
		  uint8_t src_max_voltage;
		  uint8_t src_min_voltage;
		  (void)memcpy(&PDO, &EPR, sizeof(PDO));
		  src_power = PDO.PDPIn1W;
		  src_min_voltage=PDO.MinVoltageIn100mV/10;
		  src_max_voltage=PDO.MaxVoltageIn100mV/10;
		  DPM_USER_DEBUG_TRACE(PortNum, "EPR: %d W, Max %d V", src_power, src_max_voltage);

		  if((EPR&0b11000000000000000000000000000000UL)!=0b11000000000000000000000000000000UL) //if not AVS
		  {
			  DPM_USER_DEBUG_TRACE(PortNum, "0x%08lX", EPR);
			  EPR_Voltage=(EPR>>10);
			  EPR_Voltage=EPR_Voltage&0b00000000000000000000001111111111;
			  EPR_Voltage=EPR_Voltage*50;
			  EPR_Current=EPR&0b00000000000000000000001111111111;
			  EPR_Current=EPR_Current*10; //prąd w mA
			  DPM_USER_DEBUG_TRACE(PortNum, "EPR = %lu mV, %lu mA", EPR_Voltage, EPR_Current);

		  }
		  if((EPR&0b11000000000000000000000000000000UL)==0b11000000000000000000000000000000UL) //if AVS
		  {
			  DPM_USER_DEBUG_TRACE(PortNum, "0x%08lX", EPR);
			  uint32_t Max_Voltage_100mV=(EPR>>17);
			  Max_Voltage_100mV =  Max_Voltage_100mV&0b00000000000000000000000111111111;
			  DPM_USER_DEBUG_TRACE(PortNum, "EPR AVS - max voltage: %lu mV", (Max_Voltage_100mV*100));
		  }
	  }
	  break;

and in USBPD_DPM_SNK_EvaluateCapabilities:

{
		USBPD_SNKRDO_TypeDef rdo;
		rdo.d32=0;
		DPM_USER_DEBUG_TRACE(PortNum, "AVS mode");
		rdo.AVSRDO.EPR_Capable=1;
		rdo.AVSRDO.ObjectPosition=9;
		rdo.AVSRDO.OutputVoltageIn25mV=960; //24V
		rdo.AVSRDO.OperatingCurrentIn50mAunits=100U; //5A
		rdo.AVSRDO.NoUSBSuspend=0;
		rdo.AVSRDO.USBCommunicationsCapable=0;
		rdo.AVSRDO.CapabilityMismatch=0;
		rdo.AVSRDO.Reserved1=0;
		rdo.AVSRDO.Reserved2=0;
		rdo.AVSRDO.Reserved3=0;

		DPM_USER_DEBUG_TRACE(PortNum, "RDO after evaluation: 0x%08lX", rdo.d32);
		//PDO_Parameters=rdo.d32; //for further use
		//PDO_Position=rdo.AVSRDO.ObjectPosition; //for further use
		*PtrPowerObjectType=USBPD_CORE_PDO_TYPE_AVSPDO;
		*PtrRequestData=rdo.d32;
	}

The EPR contract is OK, I have no reset and voltage 24V from source:-)

Thank You all

Hi @Jaroslaw_T

Thank you for the question.

I'm working on new knowledge base article on How to create an EPR capable USB PD Source and Sink on STM32 using TCPP ports . For demo, VBUS is kept at 5 V even for higher SPR/EPR PDOs; only the protocol is exercised (not full EPR explicit contract).

Is any way to receive PDO and APDO greater than 21V PPS? Unfortunatelly I have in my trace messages with max APDO 21V and PDO 20V.

Hello @Jaroslaw_T

You need to redefine PDO to support EPR:

uint32_t PORT0_PDO_ListSRC[USBPD_MAX_NB_PDO] =
{
#ifndef _EPR_SRC
 /* PDO 1 */ (0x00019096U),
#else /*_EPR_SRC*/

 ((PWR_V_50MV(5)) << USBPD_PDO_SRC_FIXED_VOLTAGE_Pos) |
 USBPD_PDO_SRC_FIXED_PEAKCURRENT_EQUAL |
#if defined(_EPR_SRC)
 USBPD_PDO_SRC_FIXED_EPR_SUPPORTED |
#endif /* _EPR_SRC */
#if defined(USBPD_REV30_SUPPORT)
#if defined(_UNCHUNKED_SUPPORT)
 USBPD_PDO_SRC_FIXED_UNCHUNK_SUPPORTED |
#else
 USBPD_PDO_SRC_FIXED_UNCHUNK_NOT_SUPPORTED |
#endif /* _UNCHUNKED_SUPPORT */

 ),
 /* PDO 2 */(0x00000000U),

Thank You, but I have sink device, not source.

Will the USB PD stack for STM32G0 support PD3.1 (EPR mode)? I have project with STM32G0 microcontroller because of low cost and unfortunatelly I can't use other uC.

I read that X-CUBE-TCPP supports PD3.1, but how to use it without any TCPP IC? Is it posiible any way.

Now I have downloaded the MW from github.com page: https://github.com/STMicroelectronics/stm32-mw-usbpd-core/tree/main and after the files update the EPR mode seems to be working.

In my code (usbpd_dpm_user.c):

USBPD_StatusTypeDef USBPD_DPM_UserInit(void)
{
/* USER CODE BEGIN USBPD_DPM_UserInit */
	DPM_Params[0].PE_SpecRevision=USBPD_SPECIFICATION_REV3;
	DPM_Settings[0].PE_PD3_Support.d.Is_EPR_Supported_SNK=USBPD_TRUE;
	return USBPD_OK;
/* USER CODE END USBPD_DPM_UserInit */
}

In function USBPD_DPM_Notification:

switch(EventVal)
 {
 case USBPD_NOTIFY_POWER_EXPLICIT_CONTRACT :
 {
 	USBPD_PE_Request_EPRModeEnter(PortNum);
 }
 break;

In function USBPD_DPM_SNK_EvaluateCapabilities:

USBPD_SNKRDO_TypeDef rdo;
	rdo.d32=0U;
	if(DPM_Settings[PortNum].PE_PD3_Support.d.Is_EPR_Supported_SNK==USBPD_TRUE&&DPM_Params[PortNum].PE_SpecRevision>=USBPD_SPECIFICATION_REV3)
	{
		rdo.FixedVariableRDO.EPR_Capable=1U;
	}
	else
	{
		rdo.FixedVariableRDO.EPR_Capable=0U;
	}

By the way - will the middleware update be officially available as an STM32Cube package update?

How to access to full data with all EPR PDOs and APDOs? I have no DPM_Ports.

Hi @Jaroslaw_T

Sorry for not getting back to you sooner. I will clarify this part in the article. Chucking is mandatory in EPR mode in PD3.1;

Now in your case I'm suspecting your handling of extended/chunked messages; can you test with the following source example. Here is my HW setup:

For my case, to store received SRC EPR PDOs

case USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR:
 if (Size <= (USBPD_MAX_NB_PDO * 4))
 {
 uint8_t *pdo;
 DPM_Ports[PortNum].DPM_NumberOfRcvSRCEPRPDO = (Size / 4);
 for (index = 0; index < (Size / 4); index++)
 {
 pdo = (uint8_t *)&DPM_Ports[PortNum].DPM_ListOfRcvSRCEPRPDO[index];
 memcpy(pdo, Ptr + index * 4U, 4U);
 }
 }
 break;

Can you replace your source and attach it to the Sink with the proposed setup?

Thank You

Unfortunately I have only setup for SINK. For my solution I have my own PCB with STM32G071KBT6 uC. Also I have no DPM_Ports. In USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR I have only 4 bytes of data.

Thanks for the clarification @Jaroslaw_T .

Can you verify whether the source used advertises EPR capabilities using chunked or unchunked extended messages?

During the test I have discovered, that "EPR" variable in my code (below) takes on the different value depending on the "x" variable. I.e. x=1 -> EPR=0xD230968C, so Max_voltage_100mV*100=28000. Once I have 4 bytes (Size = 4). How to recognize all PDO and APDO values?

case USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR:
	 {
		 uint32_t x=1;
		 uint32_t EPR_1=0;
		 uint32_t EPR_2=0;
		 uint32_t EPR_3=0;
		 uint32_t EPR_4=0;
		 uint32_t EPR=0;
		 DPM_USER_DEBUG_TRACE(PortNum, "EPR - received: %lu bytes", Size);
		 EPR_1=0;
		 EPR_2=0;
		 EPR_3=0;
		 EPR_4=0;
		 EPR=0;
		 EPR_1=(uint32_t)Ptr[x*4U+0U]<<0;
		 EPR_2=(uint32_t)Ptr[x*4U+1U]<<8;
		 EPR_3=(uint32_t)Ptr[x*4U+2U]<<16;
		 EPR_4=(uint32_t)Ptr[x*4U+3U]<<24;
		 EPR=EPR_1|EPR_2|EPR_3|EPR_4;
		 DPM_USER_DEBUG_TRACE(PortNum, "0x%08lX", EPR);
		 uint32_t Max_Voltage_100mV=(EPR>>17);
		 Max_Voltage_100mV = Max_Voltage_100mV&0b00000000000000000000000111111111;
		 DPM_USER_DEBUG_TRACE(PortNum, "EPR - max voltage: %lu mV", (Max_Voltage_100mV*100));
	 }

OK @Jaroslaw_T since USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR only exposes the first 4 bytes of the reassembled extended payload and source is sending properly chunked messages, the limitation appears to be in the middleware. Could you confirm reproducing using latest version of stm32-mw-usbpd-core v5.4? If possible to reproduce on one of our reference boards to confirm the issue is not linked to your hardware setup.

Yes, @FBL I have using the last USPPD core (v5.4) from GITHUB.

I have modified my code and I found:

for "x" = 0 - I have information about EPR PDO,

for "x" = 1- I have information about EPR APDO

But how to recognize the max number of "x"?

My code after changing:

case USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR:
	 {
		 uint32_t x=0;
		 uint32_t EPR_1=0;
		 uint32_t EPR_2=0;
		 uint32_t EPR_3=0;
		 uint32_t EPR_4=0;
		 uint32_t EPR=0;
		 DPM_USER_DEBUG_TRACE(PortNum, "EPR - received: %lu bytes", Size);
		 EPR_1=0;
		 EPR_2=0;
		 EPR_3=0;
		 EPR_4=0;
		 EPR=0;
		 EPR_1=(uint32_t)Ptr[x*4U+0U]<<0;
		 EPR_2=(uint32_t)Ptr[x*4U+1U]<<8;
		 EPR_3=(uint32_t)Ptr[x*4U+2U]<<16;
		 EPR_4=(uint32_t)Ptr[x*4U+3U]<<24;
		 EPR=EPR_1|EPR_2|EPR_3|EPR_4;
		 if((EPR&0b11000000000000000000000000000000UL)!=0b11000000000000000000000000000000UL)
		 {
			 DPM_USER_DEBUG_TRACE(PortNum, "0x%08lX", EPR);
			 EPR_Voltage=(EPR>>10);
			 EPR_Voltage=EPR_Voltage&0b00000000000000000000001111111111;
			 EPR_Voltage=EPR_Voltage*50;
			 EPR_Current=EPR&0b00000000000000000000001111111111;
			 EPR_Current=EPR_Current*10;
			 DPM_USER_DEBUG_TRACE(PortNum, "EPR = %lu mV, %lu mA", EPR_Voltage, EPR_Current);

		 }
		 if((EPR&0b11000000000000000000000000000000UL)==0b11000000000000000000000000000000UL)
		 {
			 DPM_USER_DEBUG_TRACE(PortNum, "0x%08lX", EPR);
			 uint32_t Max_Voltage_100mV=(EPR>>17);
			 Max_Voltage_100mV = Max_Voltage_100mV&0b00000000000000000000000111111111;
			 DPM_USER_DEBUG_TRACE(PortNum, "EPR - max voltage: %lu mV", (Max_Voltage_100mV*100));
		 }
	 }
	 break;

In the next step I have used global variable Number_Of_EPR_PDO:

main.c

uint8_t Number_Of_EPR_PDO = 0;

main.h

extern uint8_t Number_Of_EPR_PDO;

And in usbpd_dpm_user.c I have information about 1 PDO (Number_Of_EPR_PDO = 1)

case USBPD_CORE_DATATYPE_RCV_SRC_PDO_EPR:
	 {
		 Number_Of_EPR_PDO++;
		 uint8_t x=0;
		 uint32_t EPR_1=0;
		 uint32_t EPR_2=0;
		 uint32_t EPR_3=0;
		 uint32_t EPR_4=0;
		 uint32_t EPR=0;
		 DPM_USER_DEBUG_TRACE(PortNum, "EPR - received: %lu bytes, %d PDOs", Size, Number_Of_EPR_PDO);

1507	DEBUG	1050	1	EPR - received: 4 bytes, 1 PDOs

Hello community

I have done another test.

In trace I have 9 positions - last one is AVS 15 - 28V, 140W:

2707	IN	1048	1	SOP	s:014	 PD3	 H:0xB5B1 	(id:2, DR:DFP, PR:SRC) 	EXT_EPR_SOURCE_CAPA	EXT:CNu1Ch1CReq0DSiz36 [ CHUNK END ] / EPR SOURCE CAPA / 	 [1] Fixed : 5V - 3A / [2] Fixed : 9V - 3A / [3] Fixed : 12V - 3A / [4] Fixed : 15V - 3A / [5] Fixed : 20V - 5A / [6] EPR : [11V - 3.3V] - 60W / [7] EPR : [21V - 3.3V] - 60W / [8] Fixed : 28V - 5A / [9] EPR : [28V - 15V] - 140W / 	DATA: A4C1F4C188008C9630D2

So I have tried to choose 9 position:

DPM_USER_DEBUG_TRACE(PortNum, "AVS mode");
		rdo.d32=0;
		rdo.AVSRDO.EPR_Capable=1U;
		rdo.AVSRDO.ObjectPosition=9;
		rdo.AVSRDO.OutputVoltageIn25mV=960;
		rdo.AVSRDO.OperatingCurrentIn50mAunits=60U; //3A
		rdo.AVSRDO.NoUSBSuspend=USBPD_ENABLE;
		rdo.AVSRDO.USBCommunicationsCapable=USBPD_ENABLE;
		rdo.AVSRDO.CapabilityMismatch=0;
		*PtrPowerObjectType=USBPD_CORE_PDO_TYPE_AVSPDO;
		*PtrRequestData=rdo.d32;

But the stack sent strange values:

2720	PE	1050	1	PE_SNK_EVALUATE_CAPABILITY
2721	DEBUG	1052	1	AVS mode
2722	PE	1052	1	PE_SNK_SEND_REQUEST

2727	IN	1055	1	HRST
2728	NOTIF	1055	1	HARDRESET_RX

Why?

Best regards

Jaroslaw
