| keesj | Whe I read risc-v in combo with fpga I always wonder if the risc-v is hard ip or not | 06:44 |
| keesj | so.. here " complete hardened quad core 64-bit RISC-V processor " is probably still a soft core? | 06:45 |
| daveshah | This time its pretty clearly hard IP | 06:52 |
| daveshah | If nothing else a quad core RV64GC is unlikely to fit in a 25k FPGA | 06:53 |
| keesj | I see and the document abobe is more clear on that topic https://www.cnx-software.com/wp-content/uploads/2019/12/PolarFire-SoC-FPGA-Block-Diagram.png there is even a 5th core RISC-V Monitor core | 07:03 |

| mithro | daveshah / keesj: I'm pretty sure it is a SiFive based core complex in the PolarFire board | 14:46 |
| mithro | Given Microsemi's history with pricing -- I can't see it being cheap | 14:46 |
| daveshah | The board might be cheap-ish but the chips definitely won't be | 14:48 |
| daveshah | Microsemi is pretty close to "if you have to ask you can't afford it" pricing strategy | 14:49 |
| daveshah | and their usual customer base don't need to ask... | 14:49 |
| sorear | it's very definitely sifive-based, they've said as much | 14:55 |

| mithro | This is cool -> https://twitter.com/Obijuan_cube/status/1276229283145551876 | 19:18 |
| _florent_ | somlo: it's indeed still a work in progress, i'll continue tomorrow, but upstream litex/litesdcard should be working | 20:07 |
| somlo | _florent_: with 4094a6ec (litex) and 7e23147 (litesdcard), using rocket and nexys4ddr, it hangs at "booting from sdcard in sd-mode" (or somesuch, I don't have it in front of me right now) | 20:20 |
| somlo | rebuilt it in spi-mode, which is why I can't give you the exact quote :) But it hangs there, won't fall through to netbooting, or to the LiteX bios prompt | 20:21 |
