I'm not sure at which point your code is called, but do you have working BSS?
README:
[...]
lowlevel_init():
- no global_data or BSS
[...]
board_init_f():
[...]
- global_data is available
- stack is in SRAM
- BSS is not available, so you cannot use global/static
variables,
only stack variables and global_data
> Any idea on how to debug further ?
>
maybe you can add a field to global_data ?
