I’m trying to redirect the mongoose logs (those created using the LOG macro) to a file either on the flash or SD card file systems. Is this doable? I see it can be directed to a different UART or to other sinks, but I didn’t see a way to direct to a file.
Ah thanks! I checked it out and have two questions.
I wanted to disable log output to all the UARTs, since I want to use those to send data to another device. Looking at these docs:
I see I can control which UART the data goes to. It does not say so, but if I set it to -1 I can disable the output. Is this the right way to do it or will it cause me a problem?
mos config-set debug.stderr_uart=-1 mos config-set debug.stdout_uart=-1
Also, I wanted to make a separate directory for system log files. Looking here:
I see I can create virtual directory paths (since the FS is flat) but if I set the target for the log file there I get a core dump:
filesystem: - fs - fs/syslog - fs/log config_schema: - ["file_logger.dir", "/syslog"]
Did I set it wrong?
filesystem directive in
mos.yml tells mos where to find the files from your computer when creating the device’s filesystem image. The device’s filesystem is flat, i.e. everything from
fs/log go in the root directory.
If you want to direct the log files to a different directory, yo can create an adittional filesystem.
