Not recommended for future use with OpenWrt due to low flash/ram.
Limitations in extensibility and stability of operation are to be expected.
See 432_warning for details.
DSL will not work at all on devices with BCM63xx DSL chipset (due to unavailability of FLOSS driver for Broadcom chips). Consider this when chosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported.
See broadcom_dsl, dsl_modem and soc.broadcom.bcm63xx for details.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
