I used stm32f429i-disco:nsh configuration example ,and just enable the fat filesystem . The ramdisk can be created ,but mkfatfs can not work.

mount -t fatfs -o forceformat /dev/ram10 /data

It took me a long time to solve this problem. The main reason is that I use WSL and vscode. Some incorrect configurations lead to incorrect header files. I changed to Ubuntu 18.04, recompiled, and the command can be executed. Thank anjiahao1 for the advice, but the answer is wrong. Please see my screenshot.

Yes. mount does not know what is -t fatfs and vfat does not have -o forceformat option (it is from littlefs). So if I understand correctly the issue is resolved and can be closed?

Yes，it can be closed now。Thank you。

In my case, nsh can't found mkfatfs command. How can I configuration to enable mkfatfs? Thank you! image

From menuconfig, type a forward slash and it will open a search function. Type MKFATFS and it will show you that FSUTILS_MKFATFS is what you need, and it is dependent on FS_FAT etc. It even tells you if those dependencies are enabled.

You can type the number of the relevant search result (1, in this case) and it will take you directly to the menuconfig entry, assuming the dependencies allow it to be visible.

HTH!
