| whatnick | ping daveshah ... | 23:43 |
| whatnick | Looking for a sample project for LFE5U-25F ( possibly MIPS/RISC-V core I can run micropython on) | 23:44 |
| daveshah | whatnick: Should be easy enough to change https://github.com/SymbiFlow/prjtrellis/tree/master/examples/soc_versa5g to the 25F | 23:44 |
| tpb | Title: prjtrellis/examples/soc_versa5g at master · SymbiFlow/prjtrellis · GitHub (at github.com) | 23:44 |
| daveshah | That's a simple picorv32 based SoC | 23:45 |
| daveshah | What board are you running on? | 23:45 |
| whatnick | I have the FleaFPGA | 23:45 |
| whatnick | Also how can I help with line-endings :) https://github.com/SymbiFlow/prjtrellis/issues/49#issuecomment-441478670 | 23:46 |
| tpb | Title: NextPnr build failure · Issue #49 · SymbiFlow/prjtrellis · GitHub (at github.com) | 23:46 |
| whatnick | Yes I have done picorv32 on Xilinix + Micropython, would like to do the same with the ECP5 board I have | 23:47 |
| daveshah | Line endings is probably just a case of fixing this function https://github.com/SymbiFlow/prjtrellis/blob/master/libtrellis/include/Util.hpp#L54 | 23:47 |
| tpb | Title: prjtrellis/Util.hpp at master · SymbiFlow/prjtrellis · GitHub (at github.com) | 23:47 |
| daveshah | Anyway, that SoC project should be a good place to start. Just change the device name in the Makefile and the pins in the LPF | 23:48 |
| whatnick | Looks like an OR here should do it "c != '\n'" | 23:49 |
| daveshah | Yep | 23:51 |
| whatnick | LPF ? | 23:52 |
| whatnick | -> https://github.com/SymbiFlow/prjtrellis/blob/master/examples/soc_versa5g/versa.lpf ? | 23:52 |
| tpb | Title: prjtrellis/versa.lpf at master · SymbiFlow/prjtrellis · GitHub (at github.com) | 23:52 |
| whatnick | Will have to read the manual on the pins on the board ... what changes are common ? | 23:53 |
| whatnick | daveshah: this is the docs https://github.com/Basman74/FleaFPGA-Ohm/blob/master/FleaFPGA%20Ohm%20-%20Quickstart%20Guide%20Rev%200.11.pdf | 23:55 |
| tpb | Title: FleaFPGA-Ohm/FleaFPGA Ohm - Quickstart Guide Rev 0.11.pdf at master · Basman74/FleaFPGA-Ohm · GitHub (at github.com) | 23:55 |
| daveshah | So just change out all those pins to the pinout of that board | 23:56 |
| daveshah | Might be worth looking up an existing LPF for that board | 23:56 |
| daveshah | Probably need to remove the 14 disp pins as that board doesn't have the 14 seg display (the SoC demo doesn't use it anyway) | 23:57 |
| whatnick | Cool found the LPF | 23:58 |
| whatnick | ## ***** ECP5 PIN DECLARATIONS ***** | 23:58 |
| whatnick | ## USER LED; | 23:58 |
| whatnick | IOBUF PORT "n_led1" PULLMODE=NONE IO_TYPE=LVCMOS25 ; | 23:58 |
| whatnick | LOCATE COMP "n_led1" SITE "P2" ; | 23:58 |
| whatnick | .... etc. | 23:58 |
| whatnick | The board has an HDMI out | 23:59 |
