To do a very simple testThe function of invoking EDK's symbol,edk in Sch in Ise is also simple, that is, the CPU prints a string of charactersFirst, I built an ISE projectRe-build a source Sch type and set it to the top level, named Top.schRe-build
This example is mainly from "proficient in Oracle 10g pro*c/c++ programming," the example obtained from the original book has some bugs, I changed.
