How to avoid syslink.ko removal after rebuild PSP and "make modules_install" ?

Ed Sutton

I keep running into this issue and do not know how to avoid or resolve.

Build and Install:

make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm uImage modules
sudo make modules_install INSTALL_MOD_PATH=${EZSDK}/targetfs/fs ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

Boot failure because syslink.ko has disappeared:

        PRCM for IVHD2 is Done Successfully  
PRCM Initialization completed 
FATAL: Module syslink not found.

I read that syslink is "out of tree" but do not understand what that means. Does "out of tree" mean not built with the other PSP kernel modules?

Where did EZSDK install it from then and how can I restore it?

Thanks,

Ed:

"Out of Tree" means the SysLink kernel code resides outside the Linux kernel tree.

The Makefile at the top of the EZSDK has a target for building syslink.

% make help # will list the targets.

% make syslink_clean

% make syslink

% make syslink_install

Ensure EXEC_DIR (set in Rules.make) variable points to your target file system.

If this is already being done, and still having issues, please take a look at this post and some suggestions:

Hi Gil,

Thank you very much for your informative reply!

Thank you for suggesting I check this. I had two missing characters in my EXEC_DIR path. Now that EXEC_DIR path is fixed and with the "make help" and make syslink examples you provided I think I should be able to resolve this problem faster next time without blindly doing a "make clean" and "make all".

Thank you very much for your time and assistance!
