[ELDK] ELDK Linux 2.6.29, MPC885ADS and early console

[Sylvain ANDRE]

Hello Vitaly,

finally I succeeded with your recipe, here is the result of the memory 
dump : (concatenated ASCII only)

<6>Using Freescale MPC885 ADS machine description.
<6>Using Freescale MPC885 ADS machine description.
<5>Linux version 2.6.29-rc7 (root at localhost.localdomain) (gcc version 
4.2.2) #3 Fri Apr 17 09:30:49 CEST 2009.

bad area, sig: 11 [#1].

0xFF000AD8 is the physical address of PEDAT I/O register. I use it to 
drive LEDs. Perhaps it's the reason since the beginning ...

Unfortunately I'm not at my desk during 2 weeks so I must wait to have 
the answer for this...


	Best regards
