How to see the trace?

dlacombe · October 14, 2021, 7:42am

Hello,
I want to see for example “tr_debug(“Applying quirks for ISSI”);”
How to do ?
Just modifying mbed_app.json ?
“target_overrides”: {
“*”: {
“mbed-trace.enable”: 1
}
}
Thanks for advance.

you need also to add

    mbed_trace_init();

once in your main();

I have in the main
#define MBED_CONF_MBED_TRACE_ENABLE 1
#include “mbed.h”
#include “mbed_trace.h”

mbed_trace_init();
I obtain only error messages like this
[ERR ][QSPIF]: Status register not set correctly
[ERR ][QSPIF]: Device supports Quad bus, but Quad Enable Failed
[ERR ][QSPIF]: Init - Parse Basic Param Table Failed

How to have debug messages ?
Thanks for advance

Use mbed_app.json to configure mbed-trace:

github.com

ARMmbed/mbed-os/blob/master/platform/mbed-trace/mbed_lib.json

{
    "name": "mbed-trace",
    "config": {
        "enable": {
            "help": "Used to globally enable traces.",
            "value": null
        },
        "max-level": {
            "help": "This flag is used to optimize the code size. For example, setting trace optimization level to TRACE_LEVEL_INFO will define all tr_debug() macros empty, which reduces the binary size. The possible optimization levels are TRACE_LEVEL_DEBUG, TRACE_LEVEL_INFO, TRACE_LEVEL_WARN, TRACE_LEVEL_ERROR and TRACE_LEVEL_CMD. To set the output tracing level, please use mbed_trace_config_set(TRACE_ACTIVE_LEVEL_INFO). The possible tracing levels for mbed_trace_config_set() are TRACE_ACTIVE_LEVEL_ALL, TRACE_ACTIVE_LEVEL_DEBUG (same as ALL), TRACE_ACTIVE_LEVEL_INFO, TRACE_ACTIVE_LEVEL_WARN, TRACE_ACTIVE_LEVEL_ERROR, TRACE_ACTIVE_LEVEL_CMD and TRACE_LEVEL_NONE.",
            "value": null,
            "macro_name": "MBED_TRACE_MAX_LEVEL"

        },
        "fea-ipv6": {
            "help": "Used to globally disable ipv6 tracing features.",
            "value": null
        },
        "allocator": {
            "value": "malloc",
            "macro_name": "MEM_ALLOC"
