Komendy do zaprogramowania przez Hyperterminal sektora z danymi ENV,
kiedy klasycznie uBoot nie zapisuje tych komend:


- loady

- protect off A0240000 A024ffff

- erase A0240000 A024ffff

- cp.b 84000000 A0240000 10000

- md A0240000

- crc32 A0240004 7FFC



Tak wygląda zapis logu ,
i tak musi wyglądać kiedy się programuje ten sektor z ENV:
