Hi Team,

My customer is trying to perform an Ethernet compliance test and are configuring the registers as shown in the code below, but they cannot see any Ethernet signal waveform or MDIO signal waveform. Is the code below correct?

#include "ti_board_open_close.h"
#include <drivers/mdio.h>
#include <board/ethphy.h>
#include <board/ethphy/ethphy_dp83869.h>

// When they configure ETHPHY via SysConfig, CSL_ICSS_M_PR1_MDIO_V1P7_MDIO_REGS_BASE(0x00032400U) becomes undefined and causes a compiler error so they hard-coded the value
#define KC_TASK_LAN_MDIO_BASE_ADDRESS ( CSL_ICSSM0_INTERNAL_U_BASE + (0x00032400U) )
// ETHPHY address is 0x00
#define KC_TASK_LAN_DP83869_PHY_ADDRESS (0U)

static int32_t ethphy_reg_read(uint32_t regNum, uint16_t* regVal);
static int32_t ethphy_reg_write(uint32_t regNum, uint16_t regVal);
static void enable_compliance_test(void);


static int32_t ethphy_reg_read(uint32_t regNum, uint16_t* regVal)
{
    int32_t status = SystemP_FAILURE;
    // MDIO_phyRegRead() was listed in "APIs for MDIO" within the SDK
    status = MDIO_phyRegRead(KC_TASK_LAN_MDIO_BASE_ADDRESS, NULL, KC_TASK_LAN_DP83869_PHY_ADDRESS, regNum, regVal);
    return status;
}
static int32_t ethphy_reg_write(uint32_t regNum, uint16_t regVal)
{
    int32_t status = SystemP_FAILURE;
    // MDIO_phyRegWrite() was listed in "APIs for MDIO" within the SDK
    status = MDIO_phyRegWrite(KC_TASK_LAN_MDIO_BASE_ADDRESS, NULL, KC_TASK_LAN_DP83869_PHY_ADDRESS, regNum, regVal);
    return status;
}



// Task calls the enable_compliance_test function and performs a compliance test
static void enable_compliance_test(void)
{
    int32_t status;
    uint32_t regNum;
    uint16_t regVal;
    static uint16_t regVal_1DF;
    static uint16_t regVal_1F_1;
    static uint16_t regVal_00;
    static uint16_t regVal_10;
    static uint16_t regVal_1F_2;
    static uint16_t regVal_02;

    // MDIO_initClock() was listed in "APIs for MDIO" within the SDK
    status = MDIO_initClock(KC_TASK_LAN_MDIO_BASE_ADDRESS);
    DebugP_assert(status == SystemP_SUCCESS);

    /*********************************************/
    /***** Compliance Test 100 Base Standard *****/
    /*********************************************/
    // Reset PHY
    regNum = 0x1F;
    regVal = 0x8000;
    status = ethphy_reg_write(regNum, regVal);
    DebugP_assert(status == SystemP_SUCCESS);
    // Calls ethphy_reg_read() which reads the register value configured in ethphy_reg_write above and return 0
    status = ethphy_reg_read(regNum, &regVal_1F_1);
    DebugP_assert(status == SystemP_SUCCESS);

    // Programs DUT to 100Base-TX Mode
    regNum = 0x00; 
    regVal = 0x2100;
    status = ethphy_reg_write(regNum, regVal);
    DebugP_assert(status == SystemP_SUCCESS);
    status = ethphy_reg_read(regNum, &regVal_00);
    DebugP_assert(status == SystemP_SUCCESS);

    // Programs DUT to Forced MDI or MDIX mode (0x5028)
    regNum = 0x10;
    regVal = 0x5028;
    status = ethphy_reg_write(regNum, regVal);
    DebugP_assert(status == SystemP_SUCCESS);
    status = ethphy_reg_read(regNum, &regVal_10);
    DebugP_assert(status == SystemP_SUCCESS);

    // Restart PHY
    regNum = 0x1F;
    regVal = 0x4000;
    status = ethphy_reg_write(regNum, regVal);
    DebugP_assert(status == SystemP_SUCCESS);
    status = ethphy_reg_read(regNum, &regVal_1F_2);
    DebugP_assert(status == SystemP_SUCCESS);
}

Hi Mari Tsunoda,

Please allow me some time to look into it and get back

Hi Mari,

I need more details which firmware are they using. Also who is the customer here? And which peripheral are they trying to use ICSS or CPSW?

What is the use case?

Thanks for the quick response. Let me check with customer and get back too you.

Hi Nilabh,

They are using the following:

mcu_plus_sdk_am263x_08_06_00_34
ccs1210
sysconfig_1.14.0
ti-cgt-armllvm_2.1.2.LTS

Is this what you were asking for?

Also, the are performing the compliance test for CPSW not ICSS

Best regards,

Mari Tsunoda

Hi Mari,

I would recommend the customer to start with a ent example like layer 2 example and add their code to existing example https://software-dl.ti.com/mcu-plus-sdk/esd/AM263PX/latest/exports/docs/api_guide_am263px/EXAMPLES_ENET_LAYER2_CPSW.html

Please make sure while calling the PHY apis they use the phy handles.

// When they configure ETHPHY via SysConfig, CSL_ICSS_M_PR1_MDIO_V1P7_MDIO_REGS_BASE(0x00032400U) becomes undefined and causes a compiler error so they hard-coded the value
#define KC_TASK_LAN_MDIO_BASE_ADDRESS ( CSL_ICSSM0_INTERNAL_U_BASE + (0x00032400U) )
// ETHPHY address is 0x00
#define KC_TASK_LAN_DP83869_PHY_ADDRESS (0U)

Also in the above code they have written wrong mdio base address, they have used the ICSS base address, this is incorrect. Please ask them to use above example and use APIs mentioned here to write compliance test code: software-dl.ti.com/.../group__DRV__ENETPHY.html

Hi Nilabh,

Thanks for your support on this thread. My customer was able to use the sample code to get it working.

Nilabh Anand said:

They plan on using the EnetPhy_writeReg() in the Ethernet PHY Driver. In order to acquire the phy handle, they want to use EnetPhy_open() but are unsure as to what parameters they should configure.

Is there some sample code that uses EnetPhy_open()? If not, can you provide some simple example?

Best regards,

Mari Tsunoda

Hi Mari,

Glad to know that it helped. Please ask the customer to get started with the example: https://software-dl.ti.com/mcu-plus-sdk/esd/AM263PX/latest/exports/docs/api_guide_am263px/EXAMPLES_ENET_LAYER2_CPSW.html

and modify the existing example to suit their needs, this example includes the apis even the EnetPhy_open()

Hi Nilabh,

I could not find any use of EnetPhy_open() within the example that you mentioned. I found EnetApp_open(). This is not the same right?

Best regards,

Mari

Check the file : mcu_plus_sdk\source\networking\enet\core\src\per\V1\cpsw_ioctl.c

In this file check this function

tatic int32_t Cpsw_openPortLinkWithPhy(Cpsw_Handle hCpsw,

Enet_MacPort macPort,

const CpswMacPort_Cfg *macCfg,

const EnetPhy_Cfg *phyCfg,

const EnetMacPort_Interface *mii,

const EnetMacPort_LinkCfg *linkCfg)

This calls Enet_PhyOpen();

Thanks, I will send this to my customer and see what they say.
