We are designing a product using p2020cpu refering to the design of p2020rdb-pc,booting from NOR. We use the u-boot of p1_p2_rdb_pc. It can work.
Now I want to modify the NOR's base address to 0x4f000000. So I modify the following codes in p1_p2_rdb_pc.h :
But then the board can't work. It's blank in minicom.
Where am I wrong?
