Is there a way increase the number of characters in an event log?

I am running the RPI demo project on a raspberry pi 3B right now, and sometimes it appears to crash for no reason giving me errors suggesting the GPIO, LED, and UART drivers cannot be opened. I am trying to debug this , but the error event provided gives me a path to the file is cut short by an apparent character limit on the event log message size. The following is the event log output I am trying to work with for reference:

fatalAdapter.AF_ASSERT_1,1001,EventSeverity.FATAL,Assert in file /home/fprime-dev/fprime_rpi_test/rpi_test/fprime/RPI/build-fprime-automatic-arm-, line 2866: 8

You can see that the path ends after 'build-fprime-automatic-arm- ', but this doesn't help me much and in the future I worry I will come across issues where I need this path to troubleshoot different errors.

Please let me know if there is a work around, or if I can tweak a setting to allow the event log to print the entire path regardless of its character length.

I find the easiest way to solve this is to set the configuration to use FW_RELATIVE_PATH_ASSERT instead of FW_FILENAME_ASSERT. This throws away all the path from matter (/home/.....) and displays a relative path in repository. That way you can see more.

To answer your specific question on increasing that size, you'll likely need to increase several properties:

• FW_ASSERT_DFL_MSG_LEN: assert message length
• FW_ASSERT_TEXT_SIZE: assert text size
• FW_COM_BUFFER_MAX_SIZE: com buffer size, used to carry all events thus needs to be big enough for event arguments.
• FW_LOG_STRING_MAX_SIZE: log string max size (max string for events)
• FW_LOG_TEXT_BUFFER_SIZE: buffer size for text-represented events
• Event string sizes for assert fatal adapter: e.g.: local component string sizes

Hence why it might be easier to uses the truncated version mentioned first.

Thank you. For now I will rely on gdb and your truncated method for debugging. Is there any particular reason the assert text size is limited to 120, while the string buffer size is 255?
