Varium C1100 Board support #165

Open Chiwawachiwawa opened 1 year ago

Chiwawachiwawa commented 1 year ago

Hello sir, I want to use this project on Varium C1100. This is the first time I use a similar project, but I have encountered many strange problems. I am very presumptuous. Will there be support for this development board?

eugene-tarassov commented 1 year ago

I don't plan to add support for Varium C1100. However, the board appears similar to VCU1525, so you can use VCU1525 board files as a starting point for Varium C1100.

Thank you very much for your reply sir, I would like to ask you the second question, may I ask if the scope of my modification will go beyond the ./board/C1100 folder? (if I do not modify the ethernet module or other stuffs.

No, you should not need to modify anything beyond the board/C1100 folder.

You can consider adding C1100 into board/rocket-freq to get higher CPU clock frequency. The default frequencies are rather conservative, C1100 should be able to run faster then that.

Thank you sir!

Hello sir, Sorry for bothering you again,how can I get the original codes of Rocket64z1 produced by RocketChip, if I get it, I can add external devices by myself!

I'm not sure what you mean by "the original codes". The Rocket64z1 is a config for the Berkeley Out-of-Order Machine (BOOM), it is not produced by RocketChip. The BOOM repository is checked out in generators/riscv-boom folder. The BOOM is work in progress, its architecture is extremally complex and not 100% stable yet. I don't recommend to use it unless you are an expert in BOOM.
