Have been trying to force LARGE array allocation in SDRAM. Due to a bug somewhere in compiler or configuration, arrays defined in l502_user_process.c with '#include l502_sdram_noinit.h' or '__attribute__((section('.sdram_noinit')))' directives (that should allocate array in SDRAM) wrongly allocates in MEM_L1_DATA_A and overfills it. Workaround: define large arrays with these directives in l502_streams.c and include them via 'extern'.
