Hello,
is it possible to get CBoot debug console messages?

hello MarukoBG,

here’s log level settings you should configure, it’s settings as info by default.

#define TEGRABL_LOG_CRITICAL 1U
#define TEGRABL_LOG_ERROR 2U
#define TEGRABL_LOG_WARN 3U
#define TEGRABL_LOG_INFO 4U
#define TEGRABL_LOG_DEBUG 5U

Thank you @JerryChang,
could you help me to understand where do I have to enter those settings?
Consider that I am building the CBoot only as a standalone component and I am not using the whole SDK.

Just to be clear, my goal is to understand if CBoot sends out any message during boot (as u-boot usually does) because when I boot I don’t see anything on the seriel console.

Thanks

hello MarukoBG,

please have a try to configure rules.mk to change the log levels,
or, you could adjust the settings in the header file.
thanks

$L4T_Sources/r32.4.2/Linux_for_Tegra/source/public/cboot/bootloader/partner/common/include/lib/tegrabl_debug.h

        #if defined(CONFIG_DEBUG_LOGLEVEL)
                #define TEGRABL_CURRENT_LOGLEVEL        CONFIG_DEBUG_LOGLEVEL
        #else
                #define TEGRABL_CURRENT_LOGLEVEL        TEGRABL_LOG_INFO

Actually the solution is to add this line at the beginning of
cboot/bootloader/partner/common/include/lib/tegrabl_debug.h

#define CONFIG_ENABLE_LOGLEVEL_RUNTIME

This is the output now
