Hello everyone,
I am in the process of testing and debugging an home made multi-core realized with more processor LEONIII. At the moment I'm trying to test a version of the project implemented on FPGA. I have choose OpenOCD has a base for the realization of the test, implementing the needed extension and new commands in orther to adapt the structure of the software to the Sparc instruction set. The result works very well for the test of just one isolated Leon core, but give me big problems when I made a chain of the two processors, because I don't manage to bypass one of them. I have some questions: 1) original OpenOCD, for example used on ARM unit under test, supports a multi-processor system? 2) if I have no JTAG route controller in my design, I cannot use the disable function for eliminate temporaneously a tap from the scan chain. In which way I can do a bypass of the taps using OpenOCD function? Just inserting the instruction 0x0f produce a bypass (not sure that they are bypassed) of everytaps and the next isntruction wake up all of them also if it is addressed just to one tap.
