M∞ TAMATAR at Virtual Identities, CCC Strozzina Florence

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.

Beagleboard UART recovery

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


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 # AT S7=45 S0=0 L1 V1 X4  E1 Q0
syntax error                                          

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:

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:

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!

M∞ TAMATAR at Silicondreams roundup


first MISSIONS ETERNITY TAMATAR show just closed


health monitoring sleeptracker for mission eternity pilots

probably a very interesting approach to track and collect fundamental body data of our pilots:

---health monitoring tools get popular (and cheap)--- article mentioning products (listed at the end of this post)

another another wired article about the topic:
"...Self-trackers seem eager to contribute to our knowledge about human life. The world is full of potential experiments: people experiencing some change in their lives, going on or off a diet, kicking an old habit, making a vow or a promise, going on vacation, switching from incandescent to fluorescent lighting, getting into a fight. These are potential experiments, not real experiments, because typically no data is collected and no hypotheses are formed. But with the abundance of self-tracking tools now on offer, everyday changes can become the material of careful study.

When magnifying lenses were invented, they were aimed at the cosmos. But almost immediately we turned them around and aimed them at ourselves. The telescope became a microscope. We discovered blood cells. We discovered spermatozoa. We discovered the universe of microorganisms inside ourselves. The accessible tools of self-tracking and numerical analysis offer a new kind of microscope with which to find patterns in the smallest unit of sociological analysis, the individual human. But the notion of a personal microscope isn't quite right, because insight will come not just from our own numbers but from combining them with the findings of others. Really, what we're building is what climate scientist Jesse Ausubel calls a macroscope.

The basic idea of a macroscope is to link myriad bits of natural data into a larger, readable pattern. This means computers on one side and distributed data-gathering on the other. If you want to see the climate, you gather your data with hyperlocal weather stations maintained by amateurs. If you want to see traffic, you collect info from automatic sensors placed on roadways and cars. If you want new insights into yourself, you harness the power of countless observations of small incidents of change—incidents that used to vanish without a trace. And if you want to test an idea about human nature in general, you aggregate those sets of individual observations into a population study.

The macroscope will be to our era of science what the telescope and the microscope were to earlier ones. Its power will be felt even more from the new questions it provokes than from the answers it delivers. The excitement in the self-tracking movement right now comes not just from the lure of learning things from one's own numbers but also from the promise of contributing to a new type of knowledge, using this tool we all build..."
