Memory systems, systems, recording methods and printing methods of binary logs, computer-readable storage mediums, and computer program products

A memory system, comprising:

• a memory configured to store a second instruction set using a firmware event tracer, wherein the firmware event tracer includes a plurality of event items, and the event items belong to events that occur during running of firmware in the memory system, and each event item includes a timestamp and a format string describing an event;
• and
• one or more processors coupled with the memory and configured to perform the second instruction set, wherein the second instruction set includes instructions that are able to cause the memory system to perform at least the following operations:
• in response to a print command of a binary log, obtaining the format string describing an event according to a compilation address of a local static variable corresponding to a format string in the binary log and in combination with a local static variable stored in an executable and linkable format (ELF) file in which the firmware is located;
• and
• outputting the obtained format string and a corresponding timestamp together.

A system, comprising:

• a memory system including:
• a memory configured to store a first instruction set for performing an operation for tracing an event during firmware running;
• and
• one or more processors coupled with the memory and configured to perform the first instruction set, wherein the first instruction set includes instructions that are able to cause the memory system to perform at least the following operations:
• in response to triggering of a binary log including a plurality of event items, determining a timestamp and a format string describing an event, which are included in each of the plurality of event items, wherein the event items belong to events that occur during running of firmware in the memory system;
• and
• recording, as the binary log, at least a compilation address of a local static variable corresponding to the format string describing an event and the timestamp of each event item;
• and
• a host coupled with the memory system and configured to control the memory system.
