I'm thinking of getting a Star64 to do some practical learning about operating system development and I haven't been able to find some clear/simple information about compatible equipment and the process for setting up a jtag debugging environment. Please note that my experience is mostly with software and I am really, really new to working so close to the hardware.
The Star64 schematics show GPIO pins 0 to 4 for debug trace and pins 9 to 13 for jtag HIFI4 (audio DSP). From the very little that I know about jtag this is the minimum number of pins - so minimum amount of jtag functionality.
I have been looking at the Segger J-Link Edu because it has support for the U74 and E24 SiFive cores in the Star64, but I'm not sure if it is a good choice.
Has anyone setup jtag debugging for the Star64? What hardware/software are you using and can you recommend a beginners guide that can get me started?
