Доброго времени суток!
Как заставить uboot прочитать данные из qspi и положить их в память?
uboot> echo $kernel_size
0x500000
uboot> echo $kernel_load_address
0x2080000
uboot> sf read ${kernel_load_address} 0x100000 ${kernel_size}
device 0 offset 0x100000, size 0x500000
SF: 5242880 bytes @ 0x100000 Read: OK
