你好：
我有一块335x的板子sgx一直出问题，如下：
[ 15.166797] omap_hwmod: gfx: failed to hardreset
[ 15.380110] pvrsrvkm 56000000.sgx: Unable to reset SGX!
[ 15.468460] omap_hwmod: gfx: _wait_target_ready failed: -16
[ 15.596956] PVR_K:(Error): EnableSGXClocks: pm_runtime_get_sync failed (16)
[ 15.603985] PVR_K:(Error): SysInitialise: Failed to Enable system clocks (175)
请问这个是什么原因？是硬件问题还是软件问题？
