Recently, I have not been able to understand the concept of drivers very well. Sometimes I can get a feel for it by combining some USB examples written by others, but because the ARM system does not directly explain the pin functions like the MCU, there is not a good hardware framework. Today, I watched a PPT and understood it all at once. I feel that an ARM is not that difficult. On the contrary, the more pins, the simpler it is.
I saw how to connect an external ROM to start the bootloader for s3c44b0. I understood that the initial pin is on the chip... Then I carefully combined it with the PCB schematic diagram of 2440 and found that the modules were all specified. What pin has what function... Everything became clear..
