J721EXSOMXEVM: UART port change on Ethernet Switch

Part Number: J721EXSOMXEVM

Hello,

Recently I moved to SDK 7.1 and followed the instructions mentioned in the original question for changing UART2 to UART7 on SDK 7.1. However, I don't see any log on UART7. It works on SDK 7.0 but I couldn't make it work on SDK 7.1.

Some of the things I observed are.

Changing UART instance to "7U" doesn't make any difference. "make ethfw_all" doesn't compile this code. Whereas on SDK 7.0 making the same change does take effect.

#if defined(SOC_J7200)
#define ENET_UTILS_MCU2_0_UART_INSTANCE (3U)
#else
#define ENET_UTILS_MCU2_0_UART_INSTANCE (7U)
#endif

Also I added "TISCI_DEV_UART7" in this code with no luck.

void EnetBoard_initEthFw(void)
{
    Board_initCfg boardCfg = 0U;
    Board_STATUS status;
    uint32_t i, moduleCnt, appFlags;
    uint32_t clkModuleId[] = { TISCI_DEV_DDR0,
                               TISCI_DEV_TIMER12,
                               TISCI_DEV_TIMER13,
                               TISCI_DEV_UART7, };

Any help would be great here.

Thanks,

Satish

After using this build command: "make -s ethfw_all BUILD_SOC_LIST=J721E ". Code started building now but Still, I don't see any logs on UART7.

Any debug tips would be helpful here.

Thanks,

Satish

Satish,

I don't think there was any change regarding UART handling in the Enet LLD (7.1) wrt CPSW LLD (7.0).

Could you do a clean build? From EthFw you could try calling make -s -j pdk_clean BUILD_SOC_LIST=J721E. Alternatively, you could also try clean from PDK itself.

After this, rebuild EthFw with same command from your previous post, make -s ethfw_all BUILD_SOC_LIST=J721E.

Hi Misael,

Thank you for providing pdk_clean command.

I found that SDK 7.1 Linux bootloader is broken and it is not working on our custom board. We are working with TI's Linux SDK team on it. Once this gets resolved on our board (hopefully in the next couple of days) I will return here to test your command.

Thank you again for your help here.

Hi Misael,

We can close this as I have returned to SDK 7.0 and your Original answer works.

Thanks,

Satish
