TDA4VEN-Q1: How to output SBL log to the console？

Part Number: TDA4VEN-Q1

Tool/software:

Hi TI experts,

We are testing new DDR parameters in SBL boot mode,the function call flow as main()->system_init()->Drivers_open(),the function ddr_init() in system_init() is initialized before than function uart_init() in Drivers_open().

Question:

1.How to get more details about DDR initialization on the console？

2.The folder sd_sd_hlos\j722s-evm\wkup-r5fss0-0_nortos\ti-arm-clang\generated\ seems to be automatically generated, Every time I execute 'make all', it will overwrite my modifications on the ti_drivers_config.c file.I want to know how it was generated and what the original files are？

Regards.

    Please refer this file mcu_plus_sdk_j722s_09_02_00_41/source/drivers/bootloader/bootloader.c for add log in the console.

    ti_drivers_config.c file generated from syscfg , for modifying this file please refer the source file.

    Hi Karthikeyan,

    I don't think it's necessary anymore. The current information is sufficient for me to continue developing. Thank you again.

    Regards.
