<_florent_> daveshah: thanks for the fixes, i'll try to have a better understanding of DQSBUFM and the others primitives

<whatnick> ping daveshah ...
<whatnick> Looking for a sample project for LFE5U-25F ( possibly MIPS/RISC-V core I can run micropython on)
<daveshah> whatnick: Should be easy enough to change https://github.com/SymbiFlow/prjtrellis/tree/master/examples/soc_versa5g to the 25F
<tpb> Title: prjtrellis/examples/soc_versa5g at master · SymbiFlow/prjtrellis · GitHub (at github.com)
<daveshah> That's a simple picorv32 based SoC
<daveshah> What board are you running on?
<whatnick> I have the FleaFPGA
<whatnick> Also how can I help with line-endings :) https://github.com/SymbiFlow/prjtrellis/issues/49#issuecomment-441478670
<tpb> Title: NextPnr build failure · Issue #49 · SymbiFlow/prjtrellis · GitHub (at github.com)
<whatnick> Yes I have done picorv32 on Xilinix + Micropython, would like to do the same with the ECP5 board I have
<daveshah> Line endings is probably just a case of fixing this function https://github.com/SymbiFlow/prjtrellis/blob/master/libtrellis/include/Util.hpp#L54
<tpb> Title: prjtrellis/Util.hpp at master · SymbiFlow/prjtrellis · GitHub (at github.com)
<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
<whatnick> Looks like an OR here should do it "c != '\n'"
<daveshah> Yep
<whatnick> LPF ?
<tpb> Title: prjtrellis/versa.lpf at master · SymbiFlow/prjtrellis · GitHub (at github.com)
<whatnick> Will have to read the manual on the pins on the board ... what changes are common ?
<tpb> Title: FleaFPGA-Ohm/FleaFPGA Ohm - Quickstart Guide Rev 0.11.pdf at master · Basman74/FleaFPGA-Ohm · GitHub (at github.com)
<daveshah> So just change out all those pins to the pinout of that board
<daveshah> Might be worth looking up an existing LPF for that board
<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)
<whatnick> Cool found the LPF
<whatnick> ## ***** ECP5 PIN DECLARATIONS *****
<whatnick> ## USER LED;
<whatnick> IOBUF PORT "n_led1" PULLMODE=NONE IO_TYPE=LVCMOS25 ;
<whatnick> LOCATE COMP "n_led1" SITE "P2" ;
<whatnick> .... etc.
<whatnick> The board has an HDMI out

<whatnick> I will fork pjtrellis and work on a soc_fleafpga example
<whatnick> what is the syntax of the LPF file ?
<whatnick> will open ocd will be okay push with this - ecp5-versa5g.cfg ?
<whatnick> Okay I will be back ... off to lunch
