请教一下各位大佬这个报错应该如何解决，已经搞了一上午了没解决
我按照这个教程为自己的板子编译 https://blog.csdn.net/m0_55733070/article/details/117879734?spm=1001.2014.3001.5502
报错如下：
  LD      spl/common/spl/built-in.o
  LD      spl/lib/built-in.o
  LD      spl/u-boot-spl
  OBJCOPY spl/u-boot-spl-nodtb.bin
  COPY    spl/u-boot-spl.bin
  MKSUNXI spl/sunxi-spl.bin
  BINMAN  u-boot-sunxi-with-spl.bin
binman: Must provide a board to process (use -b <board>)
make: *** [Makefile:1148：u-boot-sunxi-with-spl.bin] 错误 1

请问需要在哪里写 -b <board>吗？<board>又应该填什么呢？
