Some interesting Tegra notes:
Page 631 Strap registers
Page 632 JTAG Configuration


We need pinouts! We need UART. Here's a note on UART
Code:
This controller implements three distinct speed ranges and protocols: 2400 to 115,200 bits per second (Serial IR or SIR), 4
Megabits per second (called Fast Infrared or FIR), and 16 Megabits per second (called Very Fast Infrared or VFIR). Initial
communication starts at 9600 bits per second, and negotiations proceed either faster or slower as the link strength allows.
More to come! Feel free to add!

Come on guys ... we CAN mix development with a touch of humor, especially since laughter makes us live longer (which means rooting & modding more toys)

I have my N7 on order and root kit ready for testing.

It also has a Flux Capacitor and a Hydrostatic Rejuvenator Switch but they are only used for time travel at this point and that is a feature that will be included in a future Jelly Bean release.


I DO remember that! However, I used it in the year 2014 and here I am! Problem is..... I lost it. So I cannot time travel anymore until they release both the tablet and the update. 4.2 is Klondike and 4.3 is Lemonade.

Is it possible to use this information to unbrick a bootloader (fastboot) in the Nexus 7? There is a thread on this. using nvflash in apx mode. They are unable to recover it because of some security intervention.

I am assuming you access through the micro usb OTG cable. Is there a way to get control of the JTAG signal though the USB and a special cable?

EDITED:

From the Hack Pack I cannot actually see any mention of JTAG connections on the block diagram. I have to assume no JTAG available on the nexus 7?

    - 1.3 Ghz
    - Play store says 8 hours battery of continuous usage ... not 9
    - accelerometer* - misspelled and also should be singular

    had to do it
