I'm not going to argue with practice: it always has precedence.
But it’s counterintuitive – usually decreasing the size of the heap causes VM to go into gc more often, which, for end user, looks like a computer got frozen for a while at random moments. And this is completely unproductive time for everybody and everything involved. And different users might need different settings depending on what apps they run more often and entire mixture of apps.
Nevertheless, it’s an interesting parameter to play and try to find optimal value.

Dumb question but for the "wifi supplicant" and "lcd density" edits on the build.prop, where are those?

I can't find them in the build.prop file, so I'm not sure if I am missing something, or if these need to be added.

Thanks,
Bill

Now if somebody can pass a word to setCPU's developer I'm sure he can adjust this app to work for eDGe.
Since I don't play games I'd actually want to underclock mine to prolong battery use per charge.

nandwrite -s 0x00100000 -p /dev/mtd5 ramdisk.maint.gz.crc

ramdisk.maint.gz.crc can be pulled from your update. You will need to get flash_erase and nandwrite on your device as they are only in the recovery. If you can't pull the binaries out of the new ramdisk let me know and I will pull them for you.

Copy the binaries to like /system/bin or wherever you want just not on a fat fs.
chmod 755 nandwrite
chmod 755 flash_erase

I pulled those binaries from the recovery ramdisk.

Those offsets should just affect the maintenance ramdisk but as always tread with caution as I haven't tested this.

I would also remove them once you are done for security sake.

Booting from the SD card or the USB stick?

So what do we have to modify so that uboot, the kernel and the root file system can be booted and run directly from a storage device to avoid changing the nand? I have a beagleboard that can do this. It makes testing mods so much faster. Anyone have any ideas? Are there any magic button press/holds that enable this already?

download the zip file from http://www.4shared.com/file/dwnR3GOd...ermine-09.html, rename it to update.zip and put it in usb flash driver.

Can't start to upgrade if I use the same method upgrade to Ermine(https://www.entourageedge.com/suppor...barticleid=265

Any suggestion?

If you look through the update script the locations for the bootloader are in it. I have no desire to go monkeying around with it until I get my jtag programmer and figure out how to connect it. Has anyone had any luck with that?
