The WR741ND has no such partition. To be precise, there is an user_cfg partition before the wifi calibration data. That is used by the factory firmware to store user specific settigns. We are reusign that because the factory firmware can reinitialize that with the factory reset option. On the DIR-600-Ex, the 'mac' partition contains the board specific MAC addresses at least, and it seems that there are other data as well. I guess that the original firmware uses this data to reinialize the nvram variables during factory reset. If that partition is erased, and someone wants to use the original software again, it will not be able to do a factory reset. > I also faced a strange issue which forced me to open the device and > attach the serial (and for no evident reason tftpboot didn't work > either, the device kept sending me arp requests ignoring my replies, so > I had to use Ymodem). > > Apparently, after I did "git pull; make oldconfig; make" and > sysupgraded, the resulting images ended up missing the appropriate > firmware partition splitters so it couldn't mount the rootfs after the > reboot. I have no real clue how that might have happened but "make > target/linux/clean; make" gave me a new sysupgrade image that work fine. If you are rebuilding a kernel after a kernel configuration change, it will use the modified configuration. However if the generic/platform specific kernel patches are modified, or some patches has been added/deleted those will not be used without a target/linux/clean. > Thank you again for your work.
