Hey Alison! I might've written the statement wrong. Actually, here is the output of make drivers/staging/axis-fifo YACC scripts/genksyms/parse.tab.[ch] HOSTCC scripts/genksyms/parse.tab.o HOSTCC scripts/genksyms/lex.lex.o HOSTLD scripts/genksyms/genksyms CC scripts/mod/empty.o MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/modpost.o CC scripts/mod/devicetable-offsets.s HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/sumversion.o HOSTLD scripts/mod/modpost CC kernel/bounds.s CC arch/x86/kernel/asm-offsets.s CALL scripts/checksyscalls.sh DESCEND objtool INSTALL libsubcmd_headers DESCEND bpf/resolve_btfids INSTALL libsubcmd_headers make[3]: Nothing to be done for 'drivers/staging/axis-fifo/'. > > I suspect it has never compiled for you and you need to look at > the direction in the tutorial for 'Recompiling the driver' section > and learn how to use make menuconfig. > > This driver has a couple of dependencies described in the Kconfig > file.

I did not change the driver 'Xilinx AXI-Stream FIFO IP core driver' to being compiled as a module by typing 'm'. Is that the problem here? Also, now when I try to change it by pressing 'm', it is not working. And I have tried many times but I cannot change the driver from '*' to 'm'. Thank you!
