In mid-May, a notice circulated regarding a major MCU manufacturer criticizing agents and sales for violating regulations by selling at high prices in the open market. MCU, short for Microcontroller Unit, is a microcomputer. It is small, with an ordinary MCU being about the size of a fifty-cent coin; it is inexpensive, with prices ranging … Read more
1. Introduction In previous articles, we developed applications that were embedded into the kernel within initramfs. Each time we needed to change the application, recompiling the kernel was cumbersome. Now, we will port lrzsz to enable file import and export via the serial port, making it easier to update applications by importing them into the … Read more
