Hi,
I have got a bunch of RK2706 based touchscreen player, but without anything, no drivers, no info, but the work.
Now I want to build some new application for them, so I read this thread. It's amazing what all of you find out. So I will give it a try. But I have a few starter questions.
1. Which SDK and other software I need?
I downloaded RK27SDK_NEW, these seem to be the firmware sources but no toolchain. I also got FWTools 3.0.29.02, here I also found a compiler, but I am not shure if it is for RK27xx or RK26xx or both? The Emulator from "Rockchip Emulator.rar" does not start.
2. What can I do to backup my current firmware. I managed to open the hidden partitions and can make a backup of it. As I understand the "\SYSTEM\BASE.RKW" is the main firmware file. Let's say I corrupt this file, can I somehow restore it to the player. Maybe with that RK27DM_Repair_tool_for_Rockchip_2706, which does not detect my player for now?
3. Is there a way to add applications to the player without rebuilding the whole firmware? As I understand on RK26xx you can build RKP files (Games) but on RK27xx not.
4. How can I find out some basic needed parameters of my player, like screen type and resolution, memory map, flash and so on, all I need to build a new firmware.
Maybe someone can give me a step by step instruction to get the RK27SDK firmware compiled and running on my player. I would be thankfully write a howto if I get all these things right. And of course I will share my experience and maybe the code I write.
Thank you
Thorsten
