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 ?
