问题描述
我使用K230 Linux+RT-Smart SDK 编译
make CONF=k230_canmv_only_rtt_defconfig
编译完成后，执行size查看内核大小
size -G output/k230d_canmv_only_rtt_defconfig/big/rt-smart/rtthread.elf
text data bss total filename
27900428 87121 889796 28877345 output/k230d_canmv_only_rtt_defconfig/big/rt-smart/rtthread.elf
生成代码占用28877345，如何才能节省资源。已经关闭USB和网络部分驱动了
硬件板卡
CanMV-K230d
软件版本
CanMV_K230d_sdcard_v2.0_nncase_v2.10.0
其他信息
