SPI DataFlash: Detected AT45DB021B with page size 264 Bytes, erase size 264 Bytes, total 264 KiB, revision d
=> sf erase 0 42000
SF: 270336 bytes @ 0x0 Erased: OK
=> mw.l 82000000 45444342 20000
=> sf write 82000000 0 42000
SF: 270336 bytes @ 0x0 Written: OK
=> sf read 83000000 0 42000
SF: 270336 bytes @ 0x0 Read: OK
