Illumia Icarus XL HD Research

[Cronix]

So i got my hands on a brand new Icarus XL HD yesterday,
already rooted it using kingroot (eww i know ) and installed busybox and started grabbing some info on the internals.
Ill post all my stuff in this thread.

got adb to work by modifying the build.prop file

Partition dumps: https://file-cloud.eu/index.php/s/c07LNlwGF4M96yN

dmesg: https://paste.crystalnet.org/?42fd1f...fpGJGEzQzSMNw=

build.prop: https://paste.crystalnet.org/?801285...KM/nPfRR/4VtQ=

Partitions:

mtdblock0 -> misc
mtdblock1 -> kernel
mtdblock2 -> ramdisk
mtdblock3 -> recovery
mtdblock4 -> backup (whatever that is for)
mtdblock5 -> cache
mtdblock6 -> userdata
mtdblock7 -> kpanic
mtdblock8 -> system (rootfs)
mtdblock9 -> user (sdcard)

Running kernel version 3.0.36, possibly working source: https://github.com/bq-rk3x/android_kernel_bq_rk3188


also OTG seems to be available according to the kernel boot logs:

Display Power provided by: http://www.ti.com/product/TPS65185

Touchscreen Controller: GT9271 https://focuslcds.com/wp-content/upl.../03/GT9271.pdf

the audio chip build into the device seems to be this one: http://www.mouser.com/ds/2/76/WM8904_v3.5-1075382.pdf

Used DAC is actially a wolfson: WM8918

wifi and bluetooth (4.0) are both handled by an
AP6212 chip from Ampak which also has a FM reciver builtin (i dont think that one would be wired up tho.)

processor: http://www.rockchip.nl/rk3188/

seems to be based on rk30board stuff

a bit odd: the wifi Country code seems to be hardcoded to CN (china)





I actually just openend up my reader and had a look at the internals.
seems like it could easily fit a way larger battery inside,
also it reads t80s all over the place (in the firmware and on the board physically) so it seems more and more like just a rebrand of the boyue t80s device and not a custom development based on it to me.

dont getting my hopes up yet but ive contacted icarus support asking for kernel sources.

Dear mr xxx,

Thank you for your email.
We have contacted our supplier.

We will keep in touch.

best regards,
Icarus Supportteam

UPDATE: actually that was a diffrent ticket.
my request for kernel sources was closed without any further notice a day after i created it...

[pokkis]

If you opened it, is there possibility to update SD card for bigger one?
Or is code in that SD card?

As far as I know, while the hardware supports BT 4.0, Android did not support BT 4.0 until version 4.4, so unless they provide a new firmware based on a newer Android version, we can only work with BT 3.0 (or below) devices.

Hello. Does anyone knows where can I find firmware? Tried to find at boyue and icarusreaders sites but there is none. Or maybie someone could make a backup and upload it? (would be great).
Bricked my reader now I cant use it.

Fantastic info.
I was wondering: can you understand where in the configuration they put screen update limiters? One of them should be a CPU sleep every 120s, that should be overridden by issuing Wake Locks (thanks to Guest for the idea, which I could not yet try).
The other is a screen update limit that is seen for example in remote desktop applications:

try a VNC (or TeamViewer, or other) session; on other devices, the mouse cursor is updated continuously, on the Icarus it is updated much less frequently [like every second or so?]. I have not taken stats, but I can say that you have to look for where it "randomly" went at every wrist move - you cannot see any cursor movement.

on this Icarus/Boyue device the mouse cursor - which is crucial - is updated every once in a while. On Onyx devices, it is hypnotically slow, but it is shown in a continuous flow. On this device, it appears static in unforeseeable places when fate so decides.
It has a quad core, but when using TV the CPU load is over 5...

nope not possible, as expected the "SDCARD" is emulated and a emmc chip that is soldered onto the board.

there is no update yet, i think icarus will only provide a firmware download when there has been an update to the software.

nope, havent seen anything like that so far, also sadly there is no /proc/config.gz exposed to have a look at the used kernel config, so i need to hope for the best and that icarus/buyoe will provide kernel sources according to gpl, i just dont think that they will

[jscris]

There is an update.

Do you know where it could be downloaded? Or is it updated via device only?

It came up as a notice on the device.

[Cronix]

hmm, nothing came up on mine so far

did you already update?
if not, would you mind giving me the version information that you got on the system-update screen?

[Cronix]

fun thing, the device query's boyue.com for available updates.
