In case of erased or corrupted NAND, the only output from Beagleboard you will see in your Terminal is some garbage. The bootrom does not reach the MMC bootstage anymore, or is not even able to bootload into the first or second stage (x-loader, u-boot). Pushing the User button to change the boot order to USB -> UART -> MMC -> NAND won't help either in this case. 

The Beagleboard recovery wikipage suggests three methods of which UART recovery proved to be successful.

Tools required

• the omap3 serial boot tools package
• the x-loader of your choice (e.g. x-load_revc_v3.bin.ift)
• a u-boot binary of your choice (e.g. u-boot-revc4.bin)
• Serial connection to the Beagleboard
• A SD card with FAT 32 partition

Recovery

1) Preparing the boot tools and SD card

Unpacking boot_omap3_serial.tar.bz2. The package contains an x-loader and u-boot binary that will be uploaded to the beagleboard for the rescue. Both will be replaced later by the versions from the SD card and permanently written to NAND.

tar -xjvf boot_omap3_serial.tar.bz2
cd boot_omap3_serial

Copy x-loader and u-boot to the FAT partition of the SD card

cp x-load_revc_v3.bin.ift /media/boot/x-load.bin.ift
cp u-boot-revc4.bin /media/boot/u-boot.bin

2) Upload x-loader and u-boot

First power off the beagleboard and connect the serial cable. Enter the following command to upload the temporary x-loader:

./pserial -p /dev/ttyUSB0 -f x-load.bin

Power-on the beagleboard. If there is already an x-loader in NAND push the user button so that NAND boot is tried after the UART boot.

Terminal output:

Waiting For Device ASIC ID: Press Ctrl+C to stop
ASIC ID Detected.
Sending 2ndFile:
Downloading file: 100.000% completed(12700/12700 bytes)

Upload the temporary u-boot.bin

./ukermit -p /dev/ttyUSB0 -f u-boot.bin

Terminal output:

Downloading file: 100.000% completed(162656/162656 bytes)
File Download completed

3) Connect to the temporary u-boot console

Don't reset the beagleboard, x-loader and u-boot are only in memory. Connect with the Terminal program to the beagleboard. It should display the following:

OMAP3 beagleboard.org # AT S7=45 S0=0 L1 V1 X4  E1 Q0
syntax error                                          
OMAP3 beagleboard.org #

4) Writing x-loader and u-boot to NAND

The x-loader and u-boot from the SD card need to be flashed to NAND.

Flashing the x-loader:

mmcinit 
fatload mmc 0:1 80000000 x-load.bin.ift
nand unlock
nandecc hw
nand erase 0 80000
nand write 80000000 0 80000

Flashing u-boot:

mmcinit 
fatload mmc 0:1 80000000 u-boot.bin
nand unlock
nandecc sw
nand erase 80000 160000
nand write 80000000 80000 160000

5) Restart

After restart, the Beagleboard is supposed to be revitalized!

the vulcano ash did not stop the box from AGENT FRED in BEIJING!

etoy.CORPORATION is forced to consider re-entering construction business in switzerland again to challenge narrowness, stupidity and dangerous tendencies to fight complex problems (and strange cultures) with simple / aggressive solutions.

most etoy.AGENTS think, work and party outside of the framework of religions. but the regulation of culture through a national ban on the construction of minarets is not what swiss etoy.AGENTS want.

the etoy.MUEZZIN will call for more tolerance and freedom of expression.

ihre etoy.AGENTEN bauen bereits am aktiven widerstand gegen die selbstmitleidige vereinsamung und verbloedung der eidgenossenschaft.

Alexander Klose's new book looks suuuper interesting and i wonder when i get a few days off to study the 320 pages in detail!

Dieses Buch ist überfällig und notwendig. Es entziffert unsere Kultur des 21. Jahrhunderts, eine Container- Kultur , deren Prinzipien unser alltägliches Schicksal bestimmen. (Joseph Vogl)

the book is based on Klose's dissertation. in 2005 fabio gramazio represented etoy in a conference organized by klose and volksbuehne berlin because i could not attend (still regret that so much).

get the book here for 20 euro

an english translation hopefully follows

hebeschiebetuer and big window for tank17 arrived from hungary today. etoy.TANK-PLANT BINZ is 0.75t more heavy. management wellnes level is expected to increase by 17.667%. etoy.STOCK went up 0.1% today. market is still open: place your bids!

MOST IMPORTANT: after another construction session next week (after the opening of the show IM ANFANG WAR DAS WORT / this sunday) we will be fully compatible with zurich's fire and rescue regulations.

UPDATE: sketchup file with answers for namoc construction crew

BIG QUESTION: maybe we must change from round hole (170cm diameter) to a square hole (170x170cm). this connection from the "info tunnel" to the sarcophagus is cruitial. a square hole would allow us to create a better flow of visitors.


challenge: to channel up to 20'000 visitors a day trough the SARCOPHAGUS.

solution to at least handle up to 10'000 customers a day: a simple white wooden INFO TUNNEL in which ca 50-80 waiting visitors can be informed by a video running on 3-5 large screens (run time: 2-5 minutes ...according to the mass of people / speed).

INSIDE THE SARCOPHAGUS: between 10 and 15 people can experience a 2minute leary loop (listen watch etc).

etoy never dealt with such a massive flow of visitors and spends the first 3 days after the opening with modification of speed, information load, leary loop, customer feedback etc.

the core architecture (SARCOPHAGUS) looks like this:
