_florent_mithro: cool, thanks05:32
_florent_mithro: next step: go further in the inception demo daveshah presented and also run LiteX/Migen (+Yosys/Nextpnr ) :)05:36
futarisIRCcloud_florent_: We can already do that in qemu. Should be trivial enough to run it on hardware.05:58
_florent_futarisIRCcloud: nice!06:09

somloI'm at the point where I need to provide a crt0-rocket.S file (in litex/soc/software/libbase); I'm looking at existing crt0-*.S files trying to make sense of what's actually supposed to be going on -- any clues or pointers would be super helpful right now... :)15:16
somloso, assuming crt0-vexriscv.S is the "closest", looks like I need to provide an entry point to "everything" (_start), which sets up the "trap_entry" (does it have to be marked .global, since it's only ever referenced within crt0-vexriscv.S?), then initializes the bss, and calls main()15:31
somloso maybe replacing sw & lw with sd and ld is most of what I need ?15:35
somloone more: why is the "j crt_init" followed by all those nop instructions ( -- is that an alignment thing?15:36

somlo* alignment for trap_entry, that is ?15:36
