Microsemi MI-V OpenOCD support ?

[Ruslan Bukin]

Hi,

I just arrived from Embedded World 2018 where I had been playing RISC-V Foundation Scavenger Hunt game.
I collected all fifteen stickers by chatting with various RISC-V companies about operating systems and tracing support, debugging, implementations, etc.

And I won Microsemi Creative (MI-V) board!

I remember that OpenOCD was working totally fine with HiFive1, but it seems I need some extra bits to get it working with MI-V. The FTDI chip on MI-V appears as Microsemi Embedded FlashPro5 device.
I able to connect serial and I see that 'Hello World' application is running, but I am not sure what I need for OpenOCD? Should I use 'jtag' OpenOCD adapter or 'ftdi'?

Can some one point me to OpenOCD adapter and target configuration for FlashPro5, I can't find source code.
I don't have windows or linux so I can't use official tools from Microsemi.

Thanks!

Ruslan

SiFive have their own modifications to OpenOCD on their site.

The Windows version of OpenOCD doesn't work properly, and the recommendation is to use x86 linux OpenOCD in a virtual machine. That should work fine on Mac too.

You can also build and run OpenOCD on a small dev board. It's known to work on an original Raspberry Pi.

Hi Ruslan,  

You can download Microsemi SoftConsole 5.2 from the link. SoftConsole contains a few example projects that can be run directly from the IDE on the board directly :) 

If you would like to reprogram the FPGA then you will need Libero 11.8 SP3.

If you have any issue the Release Notes for SoftConsole are very helpful. 

Regards, 

Ciaran

Hi,

I think Microsemi should release their changes to OpenOCD to open source community.

Is there anyone from Microsemi here to give official statement on this?

I don't have linux/windows/mac etc, so I can't use binaries.

Thanks!
