Hi all, I have got u-boot-1.1.4 on MPC8540 board.I'm supposed to put the processor in nap mode for power mangement.I have enabled the doze mode bit initially in the power mangement register which is in u-boot-1.1.4/include/asm-ppc/immap_85xx.h,but i couldnt find any change during the execution.i have disabled the unused interfaces to reduce the power,is there any code for doing putting processor in nap mode and doing power mangement? can any one help me out of this. Thanks in advance Revathy

[U-Boot-Users] Stack pointer corruption on 8541 - short version.
by Michael 18 Jan '07

18 Jan '07

Hi all. I posted a mail describing a problem I have with stack pointer on a board with MPC8541. I figured out I gave a complicated description for a simple problem, so here it is rephrased: I get the stack pointer corrupted when returning from function call on the first functions (running in flash, L1 cache used for stack). for example, in start.S: bl foo1(), when foo1() is: void foo1() { foo2(); } void foo2() { foo3(); } The return address from foo2() is some random crap. Any ideas what could be the reason? Thanks, Michael

Thanks again. Please note that the SourceForge download page still states 1.1.6 as the latest version. http://sourceforge.net/project/showfiles.php?group_id=65938 Should I use a different download location? Regards, David. David Saada wrote: > Thanks guys. Didn't find it under the latest (1.1.6) distribution. Was > it added at a later stage? Yes. 1.1.6 came out on Nov 2, and 8360 support was added on Nov 4. Keep in mind that the latest version of U-Boot is 1.2, which includes 8360 support and was released on Jan 6.
