Microwave international media arts festival

A new breed of M∞ TAMATAR was exposed to the public on the occasion of the virtual identities exhibition opening at CCC Strozzina last week. The 16 spheres charged with content from M∞ TESTPILOT Timothy Leary are part of a carefully curated exhibition that deals with various aspects of a contemporary online self. The works shown reflect on recent developments in matters of privacy, transparency and the unlimited exposure of true personal data. See also the post `Opening Identita Virtuali` for more details.

This exhibition enquires how digital culture is redefining the characteristics and boundaries of our identity, both personal and collective. Always being available and interacting with smartphones or sharing personal thoughts or experiences through social networks are elements common to the lives of most people today. In today’s communication society, one seems to exist only if traceable online and in the constant flow of information.
Works and installations by international artists trigger a reflection on the new relationship between man and technology under the guise of the “virtual identity” with which we increasingly confront reality, at times without even realizing it.

Together with Guerilla-gardener Maurice Maggi and 12 others, etoy presents the MISSION ETERNITY TAMATAR in a concise 20 slides à 20 seconds style.

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!
