[leejason]

linux-3.4.6  SOC: ti am335x   

ahead of patch xenomai patch ,my kernel can run correctly.    after patch pipe-core-3.4.6-arm-4.patch ,and set CONFIG_IPIPE=y.   then Kernel hangs after “Starting kernel ..."    
this is my log:  
/**************start***************************************/NAND read: device 0 offset 0x280000, size 0x500000     5242880 bytes read: OK    ## Booting kernel from Legacy Image at 80007fc0 ...

open linux-tree/kernel/ipipe/Makefile  then i got                                          obj-$(CONFIG_IPIPE)     += core.o timer.o    

                       but i do not know witch function in core.c and timer.c affect my kernel .                            
could u help me with that?                                  

i have disable CONFIG_CPU_FREQ CONFIG_KGDB CONFIG_CPU_IDLE and enable CONFIG_EARLY_PRINTK.     and  set bootargs console=ttyO0,115200n8 debug earlyprintk

Since you are using Xenomai 2.6.4, could you try the latest I-pipe
patch supported by Xenomai 2.6.4, that is:
https://xenomai.org/downloads/ipipe/v3.x/arm/ipipe-core-3.14.44-arm-11.patch

Also, what kernel are you using, is it a vanilla kernel?
