Hello!
Im working on custom Hardware, related to Beaglebone black. The main part is equal to this board, so I hope you can help me.
The major hardware difference is, there is a LVDS transmitter in place of the HDMI transmitter.
The major software difference is: I’m using an old ELDK 5.3 toolchain and RootFS - details follow.
My problem is:
I build the kernel and the SGX modules, everything seems fine, including the installation on target. But executing tests, i.e. pvr2d_test, sgx_init_test, sgx_*_test causes segmentation faults.
(And I dont’t know if this correlates with my other issue: Qt5 EGLFS apps show nothing but a black screen without error messages)
My steps are:
I’m following http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black
