I test uClibc-0.9.29. It can not work on armnommu platform either.
I thought maybe the crt1.S or the __uClibc_main can not work correctly on armnommu platform. because even the helloworld program hang when run. following was my config file # # Automatically generated make config: don't edit #

Actually, if you want a changelog from 0.9.27 to 0.9.28, I did one: http://uclibc.org/lists/uclibc/2006-July/016032.html If you want a changelog for 0.9.28->0.9.29... I need to do that, yes. :) Rob
