How to enter flash mode

Instructions can be found in #See also.

APX

It is possible to use fusee with the payload uart_payload_n7.bin (for UART A). This enables building a blob.bin. The blob.bin is used with wheelie in order to enable APX access. Fusee and the payload is included in the tegra30_debrick tools repository. Wheelie source code can also be found in: #See also.

Installation

Work-in-progress mainline

Installation not supported for now.

Status

USB networking and basic tegrafb display output works.
DTS includes timings generated with the tool linked at this page Nvidia_Tegra.

Downstream

Warning: So far only booting using the fastboot boot boot.img and flashing to a micro SD card has been tested.
Commands for flashing rootfs to a micro sd card and exporting/booting the boot.img (using fastboot) can be found in the Pmbootstrap guide.

Status

Graphics is broken, USB networking with telnet and SSH works as well as the micro sd card slot.

Serial console

Warning: Use with care
It is possible to change pinmux to have serial port uarte (UART 5) available on the sdcard slot pins. A breakout board and a logic analyzer can be used to read messages. Until now, only TXD has been tested working. Changing the pinmux is done in the DTS file. Refer to #See also for breakout board info and DTS.
