The assertion fails only if both l_libname and l_name are NULL.
Thanks Andreas, you're right. Now I have resolved this issue: I need set the value to %rambar1 register in the head.S file. This register is the configure register for SRAM. Although I not use SRAM memory, but it seems I need configure this register, otherwise I will meet the issue before. I'm not sure why this fix will affect run time loader. I guess the toolchain may do some registers' check.

The reason is still tracing...The assertion fails only if both l_libname and l_name are NULL. Andreas.
