Forum Post: Missing SGX kernel modules on custom AM335x platform

I'm working on a custom platform with the AM3354 and a build related to that of the TI EVM AM335x PSP release 04.06.00.10 release.

The problem I'm seeing right now is that the kernel moduels (most importantly the SGX ones) don't seem to be build or loaded.

Here's a look at the /lib/modules/$(uname -r)/ directory on my EVM:

mike@mike-VirtualBox:~/ti-sdk-am335x-evm-06.00.00.00/filesystem/test/lib/modules/3.2.0$ ls kernel             modules.builtin.bin  modules.order        updates modules.alias      modules.dep          modules.softdep modules.alias.bin  modules.dep.bin      modules.symbols modules.builtin    modules.devname      modules.symbols.bin mike@mike-VirtualBox:~/ti-sdk-am335x-evm-06.00.00.00/filesystem/test/lib/modules/3.2.0$ cat modules.dep kernel/crypto/tcrypt.ko: kernel/drivers/scsi/scsi_wait_scan.ko: kernel/drivers/usb/gadget/g_ether.ko: kernel/drivers/usb/gadget/g_file_storage.ko: kernel/drivers/usb/gadget/g_mass_storage.ko: ...

and here's a look at what is built on my platform:

~# ls /lib/modules/3.2.03.2-am335xpsp/
modules.alias        modules.dep          modules.softdep
modules.alias.bin    modules.dep.bin      modules.symbols
modules.builtin.bin  modules.devname      modules.symbols.bin

There's no kernel directory, there nothing in the modules.dep, etc. It seems like something is missing from the build preventing all these kernel modules from being built. 

Could I get some advice on what needs to be configured/looked at/or built in order to get all the kernel modules seen in the EVM build also in my build?

Thanks.
