Rom Kitchen and ROM Usage

[sudermatt]

I have searched around but can't seem to find the exact answer to this question. I apologize if it has been covered and I missed it.

When I use a ROMKitchen, yours or Yorch's, there are optional software I can choose to add. When I do so it gives me a memory usage indicator. For example, with the 4_00_05 I currently have, Yorch asys I have 3.9 megs of space to put software in. I understand that there is 15 for Rom and 15 for RAM, RAM being what I get to use as a user.

I install almost every software program onto a storage card. The only device memory I use is the stuff various software put onto the device by default.

My question is, If I don't put any extra software, will I gain any extra space on the device? either for running program space or anything else?

Or am I just wasting the 3.9 megs I'm alotted.

Thanks,
Matt

Hi ...

There is difference between the flash ROM and RAM.

The flash ROM is usually of a fixed size of 32 MB (for XDA I at least), it's used to store the system and any ROM application code like those you select to add while cooking the ROM.

When the system starts, CE will use part of the RAM to run in addition to any other application you will run by your self. Hence, the RAM is managed by CE to be allocated for either "running" CE and applications, and the rest is for storing the DATA like e-mails, cashe files, contacts, ...etc. The RAM size can vary from 32 MB up to 128 MB

When you install non-ROM application, if you decide to install it to the device memory it will be installed to the RAM in the programs portion which will decrease the available amount of memory for either "running" applications or stored data. If it's installed on SD card, it will save the space of the code but will still run in the RAM.

So, the answer to your question is YES, you should make the max use of the available space in ROM.

Load up as many progs as possible into the rom, it saves your program/storage ram and the programs in rom cannot be lost by hard reset, if you dont use the available space in rom then it is a waste of space.

Was just wondering, but does the 'permanent save' feature require me leave some space for it on the ROM? or is that saved yet somewhere else?

Man! This is GREAT!

I hope I am not mistaken, but, if I COOK a ROM with ALL my favorite programs, I save on space (than when I install it separately), since extra space on ROM is wasted anyways?

I didnt know that! :oops:

This uses a seperate area of flash storage as far as I know.

still no easy way to build our rom without unix & a lot of retuals needed to create it! right? i understand there is a tool for XDA2 but not XDA1 which could be great
