Custom kernel on DM816x EVM

Mathias Adam

Hi,

did anyone already succeed in running a custom linux kernel (i.e., not the one from EZSDK) on the DM816x EVM?

So far I've tried kernel 3.2 from Ubuntu 12.04 Desktop for ARM/OMAP3,  and vanilla 2.6.37.6 and 3.3.4 from kernel.org.

The Ubuntu kernel at least seems to recognize the EVM, but then gives the following error:

[    0.000000] Linux version 3.2.0-23-omap (buildd@ishigaq) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu Tue Apr 10 20:24:21 UTC 2012 (Ubuntu 3.2.0-23.36-omap 3.2.14)
[    0.000000] CPU: ARMv7 Processor [413fc082] revision 2 (ARMv7), cr=10c53c7d

[    0.000000] Internal error: : 1028 [#1]

The vanilla kernels both hang after: "Starting kernel ..."

Does anybody have an idea what's wrong here?

Thanks!

    Hi Adam,

    [    0.000000] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa17f8e4

    You are trying to access 0x4817F8E4 memory address which is not accessible and 0x4817FXXX is a reserved space. (Look at the datasheet)
