I can't afford the Altera tools licence so can't debug HPS code over JTAG/Blaster as that isn't afailable with the free toolset.If I solder in a 10 pin header could I then use JTAG & a 3rd party debugger on the HPS side? (I realise teh warranty would probably be void.) If not is there any way to get this functionality?
I see from the schematic this header has a USB_DISABLE_n signal on pin 2 pulled up to VCC.If I pull this down to ground will this disable the Blaster and take it out of the JTAG chain?
According to the schematic, it's pretty clear that the intended function of the JTAG header J5 is to automatically tri-state the MAX V pins driving the JTAG chain when connecting an Altera USB adapter (or any adapter with the same pinning). Hopefully this function is supported by the actual MAX V configuration. I would give it a try.You can check the tri-state function before soldering a connector.
