Old android versions

Hi... As I can see in the forum, there were some old releases of Android, namely Kit Kat and Jellybeans, but I can't find them on the wiki page.

Can I get a link to download the images? i don't need the source code, just some images to flash and perform a couple of tests.

Re: Dual lvds with different frequencies

At this example i'm using a different second lcd, that works at 71Mhz, but sam happens with the 51Mhz. When i turn on the system, there's only video signal on lvds0. The log: imx-ipuv3 2400000.ipu: panel size = 800 x 600 imx-ipuv3 2400000.ipu: pixel clk = 40000000 imx-ipuv3 2400000.ipu: use special ...

Re: Dual lvds with different frequencies

I've been testing, and it seems now that when i set one of the displays, the other is affected too. For example, i wake the second display, and the both go to 51Mhz. If i then use fbset on fb0, both get back to 40 MHz (physically measured). Should i set a different parent for each channel? If so, Wh...

Re: Dual lvds with different frequencies

Just tried with another version we are working on, poky morty with kernel imx-rel_imx_4.1.15_1.1.0_ga-var02. Same result, same output.

I'm not sure if we are able to move to Rocko right now, so i would rather get a fix/workaround for this latest version on Morty. Do you have any suggestion?
