Hi,

 

I am facing an issue where kernel built with gcc 5.2.0 hangs the board after the device tree is loaded.

I used current poky and meta-fsl-ppc layers to compile the image.

 

Boot Log:

WARNING: adjusting available memory to 30000000

## Booting kernel from Legacy Image at 01000000 ...

   Image Name:   Linux-3.12.37-rt51

   Image Type:   PowerPC Linux Kernel Image (gzip compressed)

   Data Size:    4789208 Bytes = 4.6 MiB

   Load Address: 00000000

   Entry Point:  00000000

   Verifying Checksum ... OK

## Flattened Device Tree blob at 00e00000

   Booting using the fdt blob at 0xe00000

   Uncompressing Kernel Image ... OK

   Loading Device Tree to 03fde000, end 03fffc40 ... OK

<hang>

 

Note that this is observed only with the new v5.2.0 gcc and kernel built with gcc v4.9.1 boots just fine.

 

It appears that a similar issue was reported and fixed for e500v2 targets a year ago.
