Hi all,
I have a self made OMAP4430 based board which runs Android based on the release 4AJ2.2.. The device has no eMMC and is based on the Blaze configuration.
Unfortunately I can't get release 4AJ.2.4. running. The u-boot and the x-loader of this release are working. I can boot the android system form 4AJ.2.2.
Using the kernel of 4AJ.2.4 results in an 'segmentation oops'.
The u-boot loads the kernel and starts it. Shortly after this the x-loader is restarted. There is no output with the standard kernel config. Setting the kernel debug level to 7 I get the output shown below.
Any ideas?
Best regards,
Roman
