   Recently, I am working with P2020, I have a P2020RDB, through with the Code Warrior 10.5.1 TAP + USB,I can burn my board,uboot, linux kernel,initrd,dtb and so on. when i flash the nor flash on board,i can use the flash programer tools in IDE,and the IDE provide the "Flash Configuration File" - P10xx-P20xxRDB_P2020_NOR_FLASH.xml ,below is the content:

<?xml version="1.0" encoding="UTF-8"?>
