i use a SPI flash memory connected to SPI0 CS2, i enabled MTD and related setting while configure the linux kernel.
while start up, i could get the info:
bfin-uart.0: ttyBF0 at MMIO 0xffc00400 (irq = 29) is a BFIN-UART
bfin-uart.1: ttyBF1 at MMIO 0xffc02000 (irq = 31) is a BFIN-UART
m25p80 spi0.2: found s25fl256s1, expected m25p16
m25p80 spi0.2: s25fl256s1 (32768 Kbytes)
Creating 3 MTD partitions on "m25p80":
0x000000000000-0x000000200000 : "bootloader(spi)"
0x000000200000-0x000000500000 : "linux kernel(spi)"
0x000000500000-0x000002000000 : "file system(spi)"
bfin_wdt: initialized: timeout=20 sec (nowayout=0)
BusyBox v1.20.2 (2013-06-30 15:27:52 HKT) hush - the humble shell
but i can't find any mtdblock on the folder /dev.
and i want to know how to format the mtd3 as FAT format or other format supported by blackfin.
I want to access them via mount command as filesystem.
by the way, on the docs web, it said a tool named bonnie++, but with buildroot 2012, i didn't see this selection. any suggestion?
