Ok, this firmware is really not easy to build, but finally I have at least booted kernel and busybox running:

/ # busybox cat /proc/cpuinfo

processor       : 0
cpu family      : sh4

@perexg , can you please explain and/or document how to properly create the directory STLINUX=/opt/STM/STLinux-2.4 which is used for building? The Makefile doesn't say a word about it...

I don't remember. I think that I just installed their iso on centos 7. I have two byteswap.h files:

/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/bits/byteswap.h
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/byteswap.h

[danielkucera]

Cool, can you please find that iso or link where to get it?

And one more thing: I'm unable to link nano:

Ok, I managed to build image from scratch with installed STLinux-2.4-sh4-20141119.iso and I'd like to add a pull request with howto. But I still hit two problems:

miscutils/nandwrite.c:151:35: error: ‘MTD_FILE_MODE_RAW’ undeclared (first use in this function)

and

util-linux/blkdiscard.c:71:26: error: ‘BLKSECDISCARD’ undeclared (first use in this function)

I see two possible solutions to this:

• add patches to /patches to fix these and apply them before building

vi apps/busybox-1.26.2/miscutils/nandwrite.c
#include <linux/version.h>
#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 2, 0)
# define MTD_FILE_MODE_NORMAL MTD_MODE_NORMAL
# define MTD_FILE_MODE_RAW MTD_MODE_RAW
#endif

and

vi apps/busybox-1.26.2/util-linux/blkdiscard.c 
                        (opts & OPT_SECURE) ? BLKDISCARD : BLKDISCARD,

• disable these features like this:

@perexg , do you remember these problems? Which way you preffer?
