Android support

Hello,

Could you explain the reason why Android is not supported on the STM32MP157C-DK2?

I can't find any instructions how to install an Android image on the target? The following example references the coprocessor example for A7 and M4 cores, but misses how this is done:-

Hi @moredatalesscenter​ 

Android does not fit to DK2 because there is not enough DDR ( 1GB required) .

Guideline to install Android on target is there :

Ah. The board features suggest it's 4 Gbit DDR3L, 16 bits.

Indeed ..which mean 512MBytes. ;)

Can packages be selectively removed to create a barebones distribution that will fit into 0.5GB?

Android from AOSP can work with 512MBytes but with an impact on the overall performance (swap has a huge impact).

It's then required to limit the memory usage to the maximum:

1- limit the display resolution on the device

2- limit the number of packages started (remove all unnecessary packages which can means patching the system server to avoid starting them (ex: Telecom))

3- applications (packages) including the Launcher shall be developed considering memory usage (no animation, simple layouts (ex: use ConstrainLayout), avoid too much activity swap...)

At the end, it depends on the kind of device targeted (ex: wear device with small screen can work easily with 512MBytes DDR)
