解決"UBoot Failed to map physical memory"問題


參考資訊:
1. whycan

問題如下(將SPI Flash讀取到0x00000000的位置):

=> sf read 0 0 1024
  device 0 offset 0x0, size 0x1024
  Failed to map physical memory

解法如下(UBoot不允許Map記憶體0x00000000,但是可以使用cp.b複製到0x00000000):

=> sf read 0x80000000 0 1024
  device 0 offset 0x0, size 0x1024
  SF: 4132 bytes @ 0x0 Read: OK

=> cp.b 0x80000000 0 1024
