Supporting the MATRIX Voice (xc6slx9-2ftg256c w/ MT47H32M16 DDR2 RAM) #196

Label: type-new-project

Hello,

I'm trying to support the MATRIX Voice (xc6slx9-2ftg256c w/ MT47H32M16 DDR2 RAM, mx25l6406e SPI Flash) and deploy an lm32 CPU on its Spartan-6 to run Micropython using your project.

I created a matrix_voice.py file with the constraints in the "platforms" folder and base.py & Makefile.mk in the "targets" folder.

I'm able to enter the environment using

source scripts/enter-env.sh

After that, much of the content that would go in targets/matrix_voice/base.py for the MATRIX Voice have already been written in Verilog.

Do you know of any resources to use Migen & LiteX alongside pre-existing Verilog for things like "IDDR2", "ODDR2", "BUFG", etc? I would appreciate if someone could point me in the right direction.

Thank you!

@samreenislam - Have you gotten to the stage of a LiteX BIOS prompt?

mithro commented 5 years ago

@samreenislam FYI You can find us on irc.freenode.net on #litex & #timvideos IRC channels if you want to ask questions interactively.

Some good examples of including / using Verilog files can be found at the CPU cores at https://github.com/enjoy-digital/litex/tree/master/litex/soc/cores/cpu

Yes, I have this right now image

Struggling with the make gateware since I'm just learning Migen syntax :sweat_smile:

That is the bash prompt. The LiteX BIOS prompt comes when you do a make firmware-connect and are successfully talking serial to the BIOS running on the softcore inside the FPGA.

Oops, yeah not there yet. The bash prompt is how far I've gotten. I need to fix my /targets/matrix_voice/base.py file. Thank you for the resources!

I'll be sure to ping on the IRC channels if I need some more direction :smile:
