It's the entry of __bss_start in the GOT (Global Offset Table). But you don't need to know this. It is unrelated to your problem. > 2. Do I have to change the linker script since I have changed the TEXT_BASE? Are you sure you understood exactly what you changed, and why? > 3. Is there any other cause for hanging? RAM not correctly initialized.
