Put a line
if (sg_len == MAX_ETH_DRV_SG) diag_print("ARRAY OVERWRITE\n");
after writing sg_list.
exactly:
693: sg_list[sg_len].buf = (CYG_ADDRESS)data;
694: sg_list[sg_len].len = len; // !!!!!! largest sg_len here
is MAX_ETH_DRV_SG
new: if (sg_len == MAX_ETH_DRV_SG) diag_print("ARRAY OVERWRITE\n");
Sorry if I'm wrong.
