AM2431: Example project(enet_lwip_icssg ) without i2c EEPROM.

Hello Seong,

Thanks for reaching out to Texas Instruments E2E support forum.

So, I tried to build after deleting i2c, eeprom in syscfg.

Can you please share the modified example.syscfg file.?

Regards,

Tushar

The file won't load

I post it in text.

The build was successful by changing the project settings so that the files generated by sysconfig could be modified.
Essentially, I want to run this example code normally without eeprom. Is there no problem running if I modify the ti_board_config.c file as below?

void EnetBoard_getMacAddrList(uint8_t macAddr[][ENET_MAC_ADDR_LEN],
uint32_t maxMacEntries,
uint32_t *pAvailMacEntries)
{
int32_t status = ENET_SOK;
uint32_t macAddrCnt;
uint32_t i;
uint8_t macAddrBuf[ENET_BOARD_NUM_MACADDR_MAX * ENET_MAC_ADDR_LEN];
uint8_t numMacMax = 0;

status = 0; //EEPROM_read(gEepromHandle[CONFIG_EEPROM0], I2C_EEPROM_MAC_CTRL_OFFSET, &numMacMax, sizeof(uint8_t));
EnetAppUtils_assert(status == ENET_SOK);
EnetAppUtils_assert(ENET_GET_NUM_MAC_ADDR(numMacMax) <= ENET_BOARD_NUM_MACADDR_MAX);
macAddrCnt = EnetUtils_min(ENET_GET_NUM_MAC_ADDR(numMacMax), maxMacEntries);

EnetAppUtils_assert(pAvailMacEntries != NULL);

status = 0; //EEPROM_read(gEepromHandle[CONFIG_EEPROM0], I2C_EEPROM_MAC_DATA_OFFSET, macAddrBuf, (macAddrCnt * ENET_MAC_ADDR_LEN));
EnetAppUtils_assert(status == ENET_SOK);

/* Save only those required to meet the max number of MAC entries */
/* TODO Read number of mac addresses from the board eeprom */
for (i = 0U; i < macAddrCnt; i++)
{
memcpy(macAddr[i], &macAddrBuf[i * ENET_MAC_ADDR_LEN], ENET_MAC_ADDR_LEN);
}

*pAvailMacEntries = macAddrCnt;

if (macAddrCnt == 0U)
{
EnetAppUtils_print("EnetBoard_getMacAddrList Failed - IDK not present\n");
EnetAppUtils_assert(false);
}
}

Hello Seong,

Thanks for sharing the above details.

Hello Seong,

The driver code fetches the mac addresses from EEPROM. 

In the above code  you have commented the EEPROM read in EnetBoard_getMacAddrList(), the macAddrBuf will not be filled. This will make the EnetAppUtils_allocMac() call fail when the app wants to allocate the macAddr.

It is better if you can fill some hard-coded mac-addresses in macAddrBuf replacing the EEPROM call.

Regards,

Tushar

With reference to url below, I hard-coded mac address as follows.

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/enet_migration_guide_top.html#CustomBoardSupport

(ti_board_config.c)

void EnetBoard_getMacAddrList(uint8_t macAddr[][ENET_MAC_ADDR_LEN],
uint32_t maxMacEntries,
uint32_t *pAvailMacEntries)
{
uint32_t macAddrCnt;
uint32_t i;
uint8_t macAddrBuf[ENET_BOARD_NUM_MACADDR_MAX * ENET_MAC_ADDR_LEN];
uint8_t numMacMax = 0;

/* Fill the MAC Address */
//macAddrBuf[ENET_MAC_ADDR_LEN*0] = {0xF4, 0x84, 0x4C, 0xFB, 0xC0, 0x5C};
macAddrBuf[0] = 0xF4;
macAddrBuf[1] = 0x84;
macAddrBuf[2] = 0x4C;
macAddrBuf[3] = 0xFB;
macAddrBuf[4] = 0xC0;
macAddrBuf[5] = 0xF4;

//macAddrBuf[ENET_MAC_ADDR_LEN*1] = {0xF4, 0x84, 0x4C, 0xFB, 0xC0, 0x5D};
macAddrBuf[6] = 0xF4;
macAddrBuf[7] = 0x84;
macAddrBuf[8] = 0x4C;
macAddrBuf[9] = 0xFB;
macAddrBuf[10] = 0xC0;
macAddrBuf[11] = 0x5D;

numMacMax = 2;
macAddrCnt = EnetUtils_min(numMacMax, maxMacEntries);
EnetAppUtils_assert(pAvailMacEntries != NULL);

/* Save only those required to meet the max number of MAC entries */
/* TODO Read number of mac addresses from the board eeprom */
for (i = 0U; i < macAddrCnt; i++)
{
memcpy(macAddr[i], &macAddrBuf[i * ENET_MAC_ADDR_LEN], ENET_MAC_ADDR_LEN);
}

*pAvailMacEntries = macAddrCnt;

if (macAddrCnt == 0U)
{
EnetAppUtils_print("EnetBoard_getMacAddrList Failed - IDK not present\n");
EnetAppUtils_assert(false);
}
}

However, in the 'do while statement' of the function below, we are circling an infinite loop.

(call stack)

Enet_ioctl (ENET_IOCTL) - enet.c   <- do while infinite loop
 - EnetApp_waitForPhyAlive - test_enet.c
    - enet_lwip_example - test_enet.c

Seong Chang Kim said:

EnetApp_waitForPhyAlive - test_enet.c

Looks like not able to communicate with PHY.

Please refer below documentation for custom PHY integration and let me know if you need further help ?
