Hello,

I need help debugging an error I am observing when I try to port android on a Gumstix multitouch appliance kit (https://store.gumstix.com/index.php/multitouch-appliance-kit.htmlwith linux kernel version 2.6.37-g314f28e.

This kit includes a TI AM3703 processor.

The boot process seems to run normally, until the point where the system tries to start a shell and then several messages are displayed:

enabling adb
adb_open
shell@overo:/ $ init: untracked pid 1049 exited

BTW Blake TI Community , I may need to dispose this thread since I received an email from Gumstix Support telling me this issue could be caused because the SGX binaries are causing a kernel fault since this processor I was working with (AM3703) does not have an SGX accelerator.

I changed the AirStorm Computer On Module (with TI AM3703) for a FireStorm COM (with TI DM3730 with SGX and DSP) and the error is gone, the issue now is that I cannot import to this kernel (2.6.37) the needed driver for the display to work and the efforts I tried to include it have failed.

I believe is better if I open a new thread, but please let me know.
Thank you.
