2009-02-24 10:38:40 Reliable Network Flash Utility???

Does uClinux have any reliable network-based flash update utilities? I've used 'dd' in the past, but it seems to be very inconsistent.

Netflash seems to be broken, not sure what else my options are.

Any help is greatly appreciated.

I have the same problem. Look like nobody know about the netflash.

I have TFTP server running at IP 192.168.200.200, and a file uImage in this server.

root:/> netflash -k -b -n -r /dev/mtd2 192.168.200.200 uImage

netflash: offset is greater than device size (0).

Looklike it can not find the server and/or filename. If you type anything after "-r /dev/mtd2", you will have the same error above.

I tried to investigate this problem, and in file: uclinux-dist/user/netflash/netflash.c, when getting info about the mtd.

ioctl(rd, MEMGETINFO, &mtd_info). the mtd_info.size is ZERO.

I'll post more when I'm done the investigation.

netflash has a lot of random config options that arent respected in the build system and generally falls apart

just use the simple script i already posted to you

Your script below is working too, but other user want to solve the problem why the netflash is not working.

ftpget -uUserId -pPassword 192.168.200.200 /tmp/uImage uImage

eraseall /dev/mtd2

cat /tmp/uImage > /dev/mtd2

I found the problem in file uclinux-dist/user/netflash/netflash.c that the config macro define CONFIG_MTD is not recognize, so either include the file that containing the macro #define CONFIG_MTD, or define at the top of this file will solve the problem.
