== How to find the Silicon Revision of your OMAP35x ==
Read back a 32 bit word from the CONTROL_IDCODE Register at address: 0x4830 A204
from the read back value: 0x4B7AE02F, you can see the revision of this OMAP35x corresponds to ES3.1
== How to check system boot order == # devmem2 0x480022F0 b == How to find the SGX core revision == Perform the following commands on the target with an utility like devmem2. # devmem2 0x48004B48 w 0x2 # devmem2 0x48004B10 w 0x1 # devmem2 0x48004B00 w 0x2 # devmem2 0x50000014 from the read back value you can see the revision of the SGX Core {| border="1"|-!

Conclusion: No big difference with this test.

We assume that the mtd4 is available for test.
