The linker script uses —– to treat the binary file as a segment
When analyzing the Linux kernel compilation process, we saw that arch/arm/boot/compressed/piggy.gzip.S includes the compressed Linux kernel (arch/arm/boot/compressed/piggy.gzip): 1: .section .piggydata,#alloc</code> 2: .globl input_data</code> 3: t_data:</code> 4: .incbin “arch/arm/boot/compressed/piggy.gzip”</code> 5: .globl input_data_end</code> 6: t_data_end: Can we also use this method to use a picture as a segment of an executable program, and then access this segment […]

Dynamic linker for x86_64 architecture on Linux ld-linux-x86-64.so.2
/lib64/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2 is a dynamic linker (also called a dynamic link editor) for the x86_64 architecture on the Linux operating system. It is responsible for loading and linking dynamic libraries that are referenced at runtime (that is, when the program starts or after). Now, let’s take a closer look at its role and importance: The […]

Use ESP32+Blinker to complete the feedback of bedroom smart door lock and bedroom temperature and humidity
Initial idea: The original idea is to connect to the school’s campus network through the ESP32 board, and then access the school’s association server (only the campus network or association WiFi can connect to the association’s server), use the server’s Broker, based on the MQTT protocol, through ArduinoIDE Use C++ to burn the program on […]
