On Windows the following command (run as administrator) will set the ip address. Step 2: Set Your IP addres to “192.168.1.2” first and then start a tftp server.

Nand erase.chip NAND erase.chip: device 0 whole chip PRE STEP 1 Make a backup of your NAND ! (optionally and only works with more recent asc files so for instance this one u-boot.asc) Wait for U-Boot to load and stop auto-boot process. It still won't be fast but cuts the waiting game from multiple hours to about 20 minutes. If that makes the upload excruciatingly slow try realterm with the same settings. On windows there are some more caveats, you can try terraterm first, if it does not work, which is indicated by * signs appearing on the prompt try to set a transmit delay of 1 msec/char.

Openwrt-lantiq-p2812hnufx_nandtpl-u-boot.img I've seen flashed devices with v21.02.0 crashing, but will boot ok after only adjusting nboot paramter. My v19.07.7 -kernel- builds still fit in 2MB, v21.02.0 gets bigger.

Use this file to update your modem first before updating to snapshot or v19 and above.Īfter you installed this one going back to v18 or below needs a full from scratch install (UART and all) as the start of the root fs has moved 1MB and you will get a kernel panic. To install this larger reservation you need a kernel that is smaller then 2MB ) see the catch 22 here ) in order to solve this issue I had compiled a very barebone image a while ago which has a smaller kernel and this will fit into the 2MB reserved space. However (some) v19 and above + snapshots can be larger and need an adjustment in the reserved space for the kernel. Up to and including v18 the kernel image is smaller than 2MB and will fit in the reserved space of the older working initramfs image. Due to some issues of the initramfs there is a bit of a workaround needed for v19 and above releases.
