1. build and install
=====================
$ make
$ sudo make install
2. dnw tool usage
=====================
Connect board to PC and open minicom. Boot board and enter U-Boot command line mode.
Then run command "dnw <download address>" in U-Boot. U-Boot may print bellow message:
Insert a OTG cable into the connector!
OTG cable Connected!
Now, Waiting for DNW to transmit data
Now, you can download your file to board by follow command on PC end:
$ sudo dnw <file_to_download>
Note: If your board isn't FL Ok6410, please set right load-address via "a" option.
Above steps have only download file to board's RAM, so you need flash
it to nand via U-Boot command "nand write".
If above doesn't work, pls check if you can see bellow message in `dmesg`.
usb 1-1: new full speed USB device using uhci_hcd and address 2
usb 1-1: configuration #1 chosen from 1 choice
secbulk:secbulk probing...
secbulk:bulk out endpoint found!
===============================================
some U-Boot commands special for FL Ok6410
(1) download U-Boot
$dnw 50008000
$nand erase 0 100000
$nand write.uboot 50008000 0 100000
#dnw default load address is 0xc0000000
all in one:
$dnw 50008000 && nand erase 0 100000 && nand write.uboot 50008000 0 100000
(2) download kernel
$dnw 50008000
$nand erase 100000 500000
$nand write.e 50008000 100000 500000
all in one:
$dnw 50008000 && nand erase 100000 500000 && nand write.e 50008000 100000 500000
(3) download yaffs2 root file system
$dnw 50008000
$nand erase 600000 #erase mtdblock2 partition
$nand write.yaffs2 50008000 600000 8000000 #instead 8000000 of real image size
all in one:
$dnw 50008000 && nand erase 600000 && nand write.yaffs2 50008000 600000 8000000
(4) download ubifs/cramfs root file system
$dnw 50008000
$nand erase 600000 #erase mtdblock2 partition
$nand write.e 50008000 600000 8000000 #instead 8000000 of real image size
all in one:
$dnw 50008000 && nand erase 600000 && nand write.e 50008000 600000 8000000
(5) download jffs2 root file system
$dnw 50008000
$nand erase 600000 #erase mtdblock2 partition
$nand write.jffs2 50008000 600000 8000000 #instead 8000000 of real image size
all in one:
$dnw 50008000 && nand erase 600000 && nand write.jffs2 50008000 600000 8000000
(6) deal with bad blocks
$nand scrub
(7) set kernel arguments
To boot using ubi image:
$setenv bootargs console=ttySAC0,115200 ubi.mtd=rootfs root=ubi0:rootfs rootfstype=ubifs rw init=/linuxrc debug
$save
$reset
To boot using cramfs image:
$setenv bootargs console=ttySAC0,115200 root=/dev/mtdblock2 rootfstype=cramfs init=/linuxrc debug
$save
$reset
To boot using yaffs2 image:
$setenv bootargs "root=/dev/mtdblock2 rootfstype=yaffs2 console=ttySAC0,115200"
$save
$reset
To boot from NFS
$setenv bootargs "root=/dev/nfs nfsroot=192.168.0.231:/FileSystem-Yaffs2 \
ip=192.168.0.232:192.168.0.231:192.168.0.201:255.255.255.0:8.8.8.8:eth0:off \
console=ttySAC0,115200"
$save
# "192.168.0.231" is your host ip; "192.168.0.232" is your board's ip;
# "192.168.0.201" is gateway; "255.255.255.0" is mask.
