Tiny Core on the Beaglebone
roberts:
Script.bin, I believe, is an Allwinner specific, configuration file. It happens to be "compiled". Typically used to set devices, e.g., vga or hdmi, and screen resolutions, etc. I am not familiar with beagelboard.
Which version of arm does it support? Perhaps, I should consider posting a tarball of our rootfs then likely with your existing beagleboard kernel and modules you might have a starting point.
tinycorelinuxrocks:
The Beaglebone is ARMv7. I would love to get access to that rootfs. I'm having a hard time getting uCore to load. I tried adding the following to uEnv.txt:
fatload mmc 0 0x43100000 uCore
and changing:
bootm 0x80200000
to:
bootm 0x80200000 0x43100000
but I get the following "data abort":

Resetting CPU ...
I have the uCore file at /uCore. How can I get uCore to load so init will work?
tinycorelinuxrocks:
I've gotten farther along, but I get one of these two errors when loading the ramdisk:
RAMDISK: Couldn't find valid RAM disk image starting at 0.
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid
Is it possible that the provided uCore doesn't work on the Beaglebone?
roberts:
I have posted the rootfs for armv7 used in the allwinner build.
Hope that will be helpful.
See: http://distro.ibiblio.org/tinycorelinux/4.x/armv7/
tinycorelinuxrocks:
Thanks roberts. I wasn't able to get a shell prompt until I added rdinit=/bin/sh to my bootloader config. Should that be necessary?
May I ask why proc is unmounted by /init?
