ecos-2.0/packages/redboot/v2_0/src/net/net_io.c|623| #ifdef CYGDBG_REDBOOT_NET_DEBUG
ecos-2.0/packages/redboot/v2_0/cdl/redboot.cdl|223| cdl_option CYGDBG_REDBOOT_NET_DEBUG {
所以一共2个地方出现了CYGDBG_REDBOOT_NET_DEBUG,一个是redboot.cdl中,这是源头,另一个就是唯一引用它的net_init函数中,
所以如果加入net的debug功能,可以直接修改net_init函数中的#ifdef CYGDBG_REDBOOT_NET_DEBUG
RedBoot_init(net_init, RedBoot_INIT_LAST);
==> net_init
直接将false也改成true就行了,net_debug = true;// false;
最后还要在启动脚本中打开net_debug功能,
因为net_init还要加载flash_get_config("net_debug", &net_debug, CONFIG_BOOL);要不然就把该句干掉.
