DRA829J: UART stdio not updated on Board_init

Hi,

Sergio Medina said:

I am trying to use UART STDIO on the BOARD_SOC_DOMAIN_WKUP domain and instance 0, but while configuring it by just modifying the board params, it is not properly set

not properly set ? 

 I'm not getting this could you please explain clearly?

 i hope here you are trying to get UART logs on wkup_uart? if so please use this patchj721e_wkupuart_log.zip let us know if this works.

By "Not properly set", I mean that the log message is sent through the default uart serial port instead of the wkup_uart.

As you mentioned, I am trying get UART logs on wkup_uart. I applied the patch, and I got the same behavior. The first log is sent through the default serial port and the second one through wkup_uart, but both of them should be sent through wkup_uart.

Below, you can see the code I use to test the patch.

int32_t main()
{
Board_initParams_t init_params;
UART_HwAttrs uart_cfg;
Board_initCfg boardCfg = 0;
Board_STATUS status;
TaskP_Params taskParams;
uint32_t uart_instance = 0;

OS_init();

/* Init board */
Board_getInitParams(&init_params);
init_params.uartSocDomain = BOARD_SOC_DOMAIN_WKUP;
init_params.uartInst = uart_instance;
init_params.pscMode = BOARD_PSC_DEVICE_MODE_NONEXCLUSIVE;
Board_setInitParams(&init_params);
boardCfg = BOARD_INIT_UART_STDIO;
status = Board_init(boardCfg);
DebugP_assert(BOARD_SOK == status);

UART_printf("\n ---> Patch applied -> MCU3_0 log working on Domain: %d - Instance: %d \n", init_params.uartSocDomain, uart_instance);

/* Init UART stdio port */
UART_socGetInitCfg(uart_instance, &uart_cfg);
uart_cfg.baseAddr = CSL_WKUP_UART0_BASE;
UART_socSetInitCfg(uart_instance, &uart_cfg);
UART_stdioInit(uart_instance);

UART_printf("\n ---> MCU3_0 log working on Domain: %d - Instance: %d \n", init_params.uartSocDomain, uart_instance);

Default UART port logs

wkup_uart port logs

Would you please confirm if you are using PROCESSOR-SDK-LINUX-J721e or PROCESSOR-SDK-RTOS-J721e? and Is assistance still needed for this thread?

I solved the issue, assistance is no longer needed
