dnw tool for Linux (based on the code from internet)
**************This code is based on the code from internet. **************contact: Du, Changbin <[email protected]> 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.
