Please follow below steps(1-5) to generate specific bin(s):
STEP 1: use boot_v1.2+ by default
boot mode: new
STEP 2: choose bin generate(0=eagle.flash.bin+eagle.irom0text.bin, 1=user1.bin, 2=user2.bin)
enter (0/1/2, default 0):
ignore boot
generate bin: eagle.flash.bin+eagle.irom0text.bin
STEP 3: choose spi speed(0=20MHz, 1=26.7MHz, 2=40MHz, 3=80MHz)
enter (0/1/2/3, default 2):
spi speed: 40 MHz
STEP 4: choose spi mode(0=QIO, 1=QOUT, 2=DIO, 3=DOUT)
enter (0/1/2/3, default 0):
spi mode: QIO
STEP 5: choose spi size and map
0= 512KB( 256KB+ 256KB)
2=1024KB( 512KB+ 512KB)
3=2048KB( 512KB+ 512KB)
