android rowboat kernel build fails w/o optimizer set to -Os

Donald Russell

Trying to debug android kernel code w/BDI 3000 debugger but the optimizer gets in the way of stepping code . I tried to build with

KBUILD FLAGS set with no optimizer and the build fails. Tried -O1 and -O2 Seems to build only with

-Os flag set. is this a known condition? Is there a workaround?

Thanks

Hi Donald,

1. Could you send your config file for more analaysis from our side ?

2. is Highmem enable in config ?

BR,

Thanks for your help.

Im using the standard rowboat config on the evm and this occurs.

Not using Highmem.

Trying to debug a kernel crash during init calls on the musb driver probe on my hardware. The optimizer

is really scrambleing the relationship with the source code and the debugger making it difficult to track down.
