OMAP4 ICS build questions

Alireza Kenarsari Anhari

Hi,

I have three question regarding building ice cream sandwich for blaze (http://www.omappedia.com/wiki/L27.IS.2.P2_OMAP4_Icecream_Sandwich_Release_Notes)

1- In section "Preparing Android binaries" it is mentioned that one should create a folder called "/myfs" and copy files from "mydroid/out/target/product/blaze/" to this folder. Why this folder is needed at all? I think nobody is using during the rest of build process .... Am I missing something?

2- In the section "Creating img files" it is mentioned that one should remove all .img files from "out/target/product/blaze/" and regenerate them again. I just do not understand the logic behind it as it seems like that same .img files will be generated.

3- Is signing the x-loader mandatory or optional. In fact I did not go through this step (as I did not have access to MShield application) and I was able to load ICS on blaze successfully.

Thanks in advance,

Alireza

    Hi Alireza,

    1. The folder "myfs" is required only if you are using the SD Card for storing the Android FS. There are some steps missing in this page if you are planning to use SD Card for boot. You can find these steps in one of the earlier releases in the following link: http://www.omappedia.com/wiki/BlazeTablet_L27.13.1_Release_Notes#Booting_Kernel_and_Android_File_System_from_SD_card .

    If you are using emmc then you can skip this step of creating the "myfs" folder.

    2. The explanation is why the removal of old img files and creating new ones are given two lines below the steps you were talking about. I am copy and pasting here: If you built and installed GFX after compiling AFS, system.img and data.img will also be updated with the GFX files.

    3. The signing is x-loader is used only for HS/EMU devices with high security features. If you are using a GP device you need not sign the x-loader.
