Asus RT-AC68U
I made a pretty awesome blunder and wiped out the mtd boot partition/block. And by wiped out, I mean: dd if=/dev/zero of=/dev/mtdblock1
Now, when powering on, only the USB2 blue led comes on, with the power light faintly on. I'm _pretty_ confident this is a brick. This was an old device I got off craigslist so I'm not too worried. Out of curiosity, I'm wondering what could be done to recover.
I'm assuming that there can be no tftp because that is in the CFE?
Will anything come out of the serial port if I get one of those cables?
I have access to a hot air rework station, so it could be a fun experiment to try and flash the nand.
Also trying to understand how these work. I've thought of it like a PC, with the nand being the hard disk. What's on the various "partitions" of the mtd?
mtd0: "boot"
mtd1: "nvram"
mtd2: "linux"
mtd3: "rootfs"
mtd4: "ddwrt"
Where is the "partition table" that lays out the mtd stored?
Is there something analogous to an MBR or GPT?
Thanks!
