+ OpenWrt One
+ ***********
+
+ Hardware summary
+ ================
+
+ - MediaTek MT7981B (1300MHz)
+ - 256MB NAND Flash
+ - 1024MB RAM
+ - WLan hardware: Mediatek MT7976C
+
+ Limitations
+ ===========
+
+ Only tested over TFTP so far.
+
+ This boots and seems to mount to rootfs but seems to fail to init:
+

+[ 18.736233] with arguments:
+[ 18.739188] /bin/init

+[ 18.747281] TERM=linux
+[ 18.788942] Kernel panic - not syncing: Requested init /bin/init failed (error -2).
