Retrieving device information

This page describes how to obtain memory information and the script.bin from an A10 based device.

FEL dump (bootinfo + script.bin)
This method uses the soft FEL mode to allow easy extraction of both needed DRAM configuration and script.bin. You'll need the sunxi-tools for that.

fel read 0x42400000 0x82d0 boot1.header fel read 0x43000000 0x20000 script.bin bootinfo boot1.header bin2fex script.bin script.fex Mail the output of bootinfo and script.fex to linux-sunxi mailing list.
 * 1) Make sure you are using STOCK vendor firmware! To ensure you are using a stock memory settings and script.bin
 * 2) Power off the device.
 * 3) Hold down home button.
 * 4) Power on the device.
 * 5) While still holding down the home button press the power button at least three times.
 * 6) Release home button.
 * 7) Connect the device using USB OTG.
 * 8) From sunxi-tools on your computer run:

bootinfo from tool
This method uses a10-meminfo-static tool to extract DRAM information from any Linux based OS running originally on the device. Requires you to have root access on the device.


 * 1) Make sure you are using STOCK vendor firmware! To ensure you are using a stock memory settings and script.bin
 * 2) Download a10-meminfo-static from: https://github.com/maxnet/a10-meminfo/raw/master/a10-meminfo-static
 * 3) Put it on a FAT formatted USB memory stick or microSD card.
 * 4) Start the A10 based device without an SD card, so that you boot the original stock firmware.
 * 5) Optionally: install a terminal from app store or use SSH.
 * 6) Start a terminal (or ssh in remotely if a SSH server is installed).
 * 7) "su -"
 * 8) Insert the SD card.
 * 9) Do "mount" to see where the SD card (or USB memory stick) got mounted and note which partitions are RW mounted (and which Read-Only).
 * 10) "cat /a10-meminfo-static > /data/cache/a10-meminfo-static" where  usually is something along the line of /mnt/sdcard and where /data is mounted rw. If /data/cache is not writeable, find a location that IS writeable (from the previous step). Sometimes / is rw mounted.
 * 11) "chmod 755 /data/cache/a10-meminfo-static"
 * 12) "/data/cache/a10-meminfo-static" OR "/data/cache/a10-meminfo-static > //a10-memdump.txt" Note that for the second option, it may be required to adjust the path to sdcard.
 * 13) Send E-Mail to linux-sunxi mailing list with output copy/paste or attach the txt file.

script.bin from nanda mount

 * 1) Make sure you are using STOCK vendor firmware! To ensure you are using a stock memory settings and script.bin
 * 2) Start the A10 based device without a SD card so that you boot the original Android stock firmware.
 * 3) Optionally: install a terminal from the app store or use SSH.
 * 4) Start a terminal (or ssh in remotely if an SSH server is installed)
 * 5) "su -"
 * 6) Insert SD card.
 * 7) Do "mount" to see where the SD card (or USB memory stick) got mounted and note where nanda is mounted.
 * 8) If not mounted do: "mkdir /mnt/nanda" and "mount -t vfat /dev/block/nanda /mnt/nanda"
 * 9) "cat /script.bin > /script.bin"
 * 10) If you manually mounted "umount "
 * 11) Put script.bin somewhere where you can hyperlink it and send a link to the mailing list.

Console dump

 * 1) Make sure you are using STOCK vendor firmware! To ensure you are using a stock memory settings and script.bin
 * 2) You also need console access.
 * 3) When boot1 starts, send 1 on the serial console (or use magic key combo if supported).
 * 4) Connect USB OTG cable and copy script.bin (and .fex if available) from the virtual USB drive.
