The learning curve continues.
At this point, the very best configuration for the Eken M001 is ECOTOX v1.1.1 firmware and an sdcard partitioned with a 96MB linux swap file and swapping enabled.
I used my android phone booted in Amon_RA Recovery v1.7.0.1 to partition the sdcard.
ECOTOX is a rooted system so you're able to edit the usrinit.sh to change the swap device to mmcblk0p1, the name of the swap parititon. Once you re-boot you find you now have 195MB of available memory.
The effect is amazing! Where moving from the browser to the Home screen on stock firmware might take up to 10 seconds, it now takes barely one second.
If you have an M001 you would do yourself a favour to get. ECOTOX v1.1.1 installed and set up a swap file.
