<philtor> I'm just getting started with an OrangeCrab board, I ran through the directions in their examples and got to the point where you run 'make' in the blink directory and get:
<philtor> 2.42.16.5. Executing ABC9.
<philtor> Running ABC command: "<yosys-exe-dir>/yosys-abc" -s -f <abc-temp-dir>/abc.script 2>&1
<philtor> ABC: sh: 1: <yosys-exe-dir>/yosys-abc: Permission denied
<philtor> ERROR: ABC: execution of command ""/mnt/nas/phil/tools/oss-cad-suite/lib/yosys-abc" -s -f /tmp/yosys-abc-u97QgE/abc.script 2>&1" failed: return code 126.
<philtor> make: *** [Makefile:40: blink.json] Error 1
<philtor> it seems weird that it's trying to execute yosys-abc from the lib directory, as I can't find where that's happening in their Makefile I'm assuming yosys itself is calling this?
<philtor> yep, seems to be the case. If I run this: $ yosys -p "read_verilog blink.v; synth_ecp5 -json blink.json"
<philtor> I get the same result.
<philtor> (turns out that lib/yosys-abc is an empty file - trying to untar the archive again...)

<lofty> <philtor> Does yosys look for either a .pcf or .ccf? <-- neither
<lofty> that's handled by place-and-route
<lofty> but I suspect the actual file format varies by tooling; certainly it varies for different nextpnr architectures
<philtor> Oh, ok, so since they don't use nextpnr their p&r apparently looks for a file with a .ccf suffix.
