I have mad a BF533 PCB , when conttecting JTAG , it writes:" Failed passing SOM test".I would like to konw what is SOM test, is there some thing wrong with my PCB? Hardware or software?
Is your emulator connecting properly to other boards because SOM test is just testing the memory on the emulator itself. You may also revisit the connection of the JTAG signals with PCB.
I connected the JTAG to BF533 EZ kit Lite , it works well .
Have you verified the connections with board. Also have a look at EE-68 application note which provides technical information to properly design a JTAG emulator interface for Analog Devices, Inc. (ADI) processor targets.
