andrzejrstekern, I wonder if we could have some debugging/monitor outputs available at the mor1kx top-level01:56
andrzejrsignals like exception, sr, pc, exec_valid, instruction etc. Most of them are already available in mor1kx_cpu02:01
stekernandrzejr: there are already: https://github.com/openrisc/mor1kx/blob/master/rtl/verilog/mor1kx.v#L16807:30
andrzejr2stekern, yes, there are some indeed. my mistake. would be useful to have some flags to trigger on when debugging hw.13:18
andrzejr2various exceptions etc13:19
juliusb_hah: http://lkml.iu.edu/hypermail/linux/kernel/1510.3/02866.html14:22
heshamolofk: How was you going to send Hex/Intel format file over UART?16:59
heshamI mean from the PC part. Would you recommend an existing Linux package/program for doing so?17:02
heshamI'd try kermit17:07

juliusb_or, more interestingly: http://www.doof.me.uk/category/vhdl/17:07
salman_the I2C code in the fusesoc de0_nano seems not to have pullups enabled on the SDA and SCL lines in Altera..why not?17:18
olofkandrzejr: I think wallento has some debugging infrastructure that hooks up to the trace ports in mor1kx22:47
andrzejrhi olofk22:48
andrzejrfor hw debug it is handy to have some strobe/flag signals available at the top level. At the moment I'm modifying mor1kx to dig out some signals of interest.22:49
andrzejrI gave up eth, too much work to set up a sim/test rig and I don't need eth that badly22:51
andrzejr(DDR was a different story)22:51
andrzejr_franck_, this issue is still present in 4.2: http://opencores.org/forum,OpenRISC,0,544423:40
andrzejrjuliusb_, this is very interesting indeed. LLVM + "v-code" (an intermediate language) looks like the best solution for VHDL+Verilog+... simulation. Too bad he is targeting only VHDL.23:54
andrzejrmaybe iverilog could be made to only emit v-code and leave the rest to nvc23:55
