PicoRV32 example? #26
Comments
--hx8k --package tq144:4k works for me. |
So, I've modified the Makefile that comes with picorv32 to include the options you've provided, and I end up with:
Any idea why this is happening? Is it because the pcf file may have the wrong pin configuration? Thank you for your help! ---EDIT--- |
Yes, you were using the wrong pcf file for the Blackice II board. Another problem you will get trying to run the hx8kdemo version of PicoSoC on the Blackice II board is that the Blackice board does not have flash memory. For the Blackice II board, you either need a version that runs entirely from BRAM or one the runs from SRAM like BlackSoc - https://github.com/lawrie/icotools/tree/master/icosoc Here is a version that runs from BRAM on the Blackice Mx board. You would need to change the pcf file for that version to run on the Blackice II - https://github.com/lawrie/pico_ram_soc Another problem you will get is that the 100Mhz clock on the Blackice II is too fast to run PicoSoc and you will need to use a PLL or a clock divider. It will probably run at 50Mhz, definitely at 25MHz. You are better off discussing these things on the mystorm forum than here - https://forum.mystorm.uk/ |
@lawrie Thank you for this! I'll move the conversation to a more appropriate venue, as per your suggestion. |
Hello! I've still got my BlackIce-II board and am trying to get Clifford Wolf's PicoRV32 running on it. I'm running into some problems with getting next-pnr to create an "hx4k" pathway (I know that the tutorials recommend arachne-pnr, but that seems to have been deprecated).
If you have any recommendations for getting a risc-v core running on the board, I'd love to hear it! Thank you for your help!
