Hi,
I'm trying to get started with the new i.MX8MQ-EVK support and I've got a bit of an issue enabling ext4 read support without also enabling write support.
CONFIG_FS_EXT4=y
I get a build error here:
fs/fs.c:198:12: error: ‘ext4_write_file’ undeclared here (not in a function); did you mean ‘ext4_read_file’? .write = ext4_write_file, ^~~~~~~~~~~~~~~
This line is wrapped with an ifdef check for CONFIG_CMD_EXT4_WRITE. The write function is declared in include/ext4fs.h, where it is wrapped with a check for CONFIG_EXT4_WRITE.
The problem is that include/configs/imx8mq_evk.h has this define:
#define CONFIG_CMD_EXT4_WRITE
This results in the 'write' code being enabled in fs.c but disabled in ext4fs.h. The two ifdefs probably ought to be made consistent, but I don't really understand why imx8mq_evk.h needs to define it in the first place. Can anybody shed some light on this?
Does the change below help?
