Have you tried a kernel.org kernel?  The group here would be more than  
happy to help with any issues you might find with the kernel.org kernel.

Freescale MPC8313ERDB-RevA and newer BSP/kernel

[Mark Bishop]

Has anyone been able to get a newer Freescale BSP to work with a RevA  
(processor version 1.0) RDB?

The boards we received didn't have SPI compiled into the kernel and  
when we went to go re-compile the kernel using the 20081222 and  
20080711 BSPs.  I realize that the interrupts were reversed for eTEC1  
and eTEC2 and I've made the changes in the .dtb file and I no longer  
hang when I ping, etc.   But I still can't get the board on the  
network.  I've verified it isn't the network settings.

I've pinged Freescale for support (didn't help much) and I am now  
looking for someone who has actually done it (if ever).

Yes I have actually.  I have booted a 2.6.28.6.  Same problem.

Also, is it me but at some point from 2.6.23 to 2.6.28 did they =20
started using hex numbers in the .dts file for "interrupts =3D " without =20
the 0x preamble?

I've been looking at 2.6.20, 2.6.23, and 2.6.28 .dts files for this =20
board and .28 looked way different in the interrupt section for the =20
eTSEC.

I've booted many recent kernels on revA 8313ERDB; networking works fine. 
I'll try 2.6.28.6 specifically, though u-boot is acting up at the moment
so I have to address that first. :-(

Are you using the stock config and device tree from 2.6.28.6, or have you
made any changes?

Yes.  dts version 0 had hex by default (with OF-like radix prefixes), and version 1 (indicated by
/dts-v1/; at the top of the file) has decimal by default (with C-like
radix prefixes).

You're sure you're not trying to talk to the switch (which will claim
link-up regardless of what's plugged into it)?  The non-switch ethernet
port is eTSEC2.

What *does* it do when you ping, if neither hang nor work?

After remapping the IRQs, it is working now.

Any idea on what I need to do to get SPI working?  I've compiled it =20
into the kernel but don't see anything in /proc/bus

Re: Freescale MPC8313ERDB-RevA and newer BSP/kernel

[Vijay Nikam]

Hi Mark,

Could you please let me know how you booted the latest Linux kernel on
MPC8313ERDB board ? ? ? As I tried but was not successful. It hangs or
does nothing and waits at network configuration, mean to determine IP
address (as I have used dhcp).

Kindly please acknowledge ... thank you ...

Kind Regards,
Vijay Nikam

I modified the .dts file (mpc8313erdb.dts)

WAS interrupts = <37 0x8 36 0x8 35 0x8>;
IS  interrupts = <34 0x8 33 0x8 32 0x8>;

WAS interrupts = <34 0x8 33 0x8 32 0x8>;
IS  interrupts = <37 0x8 36 0x8 35 0x8>;

This is from memory, so let me know if you have a problem.

And sorry for the manual diff.



Any idea on how to get spidev up and running on this board?  :)

Should actually be <32 8 33 8 34 8> for newer revs.

> WAS interrupts = <34 0x8 33 0x8 32 0x8>;

Likewise, <35 8 36 8 37 8>.

Hello,

I have actually tried with this set Interrupt mappings ... needed to
be done for mpc8313erdb Rev. 1.0 board dts, but still not able to
boot. It hangs at udhcpc pre started. please check the attached
screenshot.

Please let me know the way to proceed further, Kindly please
acknowledge ... thank you
