Upgrading from 2.6.32 to 2.6.38 prevents kernel from executing init - may be related to ttyS* to ttyO* OMAP specific port mapping.
If you have had success running this or higher Kernel release with either Froyo or GB, I wil appreciate any pointers on init scripts or the like
to get around this ttyO* issue.
Thanks - JP
Hi Jehangir,
1. At present we have not enable 2.6.38
w.r.t your issue
1. could you post logs?
2. Would you elaborate on your issue? Which point you are facing this one.. booting time ? build time? Could you able to see any activity on screen ?
Hi Satish;
Here's the tail portion of console log message after I changed ttyS2 to ttyO2 in "boot.scr":

Hi Satish,
Yes. the x-loader and u-boot loads fine. Here's the complete log from power-on with kernel chatter till it hangs on init...
Note that bootargs were modified so ttyS2 -> ttyO2. Thanks - JP

Hi Jehangir,
I think this issue is not related with the console settings. They are correct.
I assume you have applied all 2.6.38 android patches.
Can you please check you have enabled the minimum android options in the kernel?
Like
a)ASHMEM support
b)Android Staging Drivers -> (Binder, Log, Low Memory Killer, RAM console)
Please check with the 2.6.32 rowboat kernel configuration or the emulator kernel configuration (/proc/config.gz)
Regards,
Arun
Hi Arun,
I'm not usre if you're referring to the bootargs or kernel .config file by options.
Neverthless, can you please send me a comprehensive minimal list of android options for 2.6.38 ?
Thanks - JP
Hi Jehangir,
I was referring to kernel config.
If you want to see android kernel differences, best way would be to do a "diff" of
omap3_evm_defconfig and omap3_evm_android_defconfig.
You can refer to below document to get more info on android specific kernel options
http://elinux.org/Android_Kernel_Features
Regards,
Arun
