Thank you for the advice, the problem is fixed. But there is another problem when i boot linux:

@CristinaZN thank you for pointing this out.

The issue is not coming from the ESP repository, but from the Leon3 mklinuximg utility.
We have recently updated our mirror of the utility to support more accelerators, however we have not merged the corresponding hardware support in ESP.

To solve the issue we have reverted the mklinuximg utility on our server. To update your copy, please run again <esp>/utils/scripts/build_leon3_toolchain.sh and repeat just this step: *** Installing mklinuximg ... ***. You may skip all other steps that would reinstall GCC and the root file system image.

As a sanity check, open /opt/leon/mklinuximg-2.6.36-2.0.3/include/ambapp.h. You should find this line:
#define AMBA_APB_SLAVES 32.

Soon we will merge hardware support for 128 APB slaves from a development branch. At that time I will post an update to this issue.

Support for 128 APB slaves is now the default in ESP. Merged with #58
