ikskuh | i guess it's time to return to FPGAs soon. someone just dropped me a FOMU last weekend | 11:30 |
---|---|---|
*** thardin <[email protected]> has left #yosys | 11:32 | |
josuah | ikskuh: they are very fun: can be programmed with dfu-util too, makes it easy | 11:54 |
ikskuh | yeah, i've seen that it tells me it's a DFU device | 11:55 |
ikskuh | but i feel a bit lost, how do i upload the bitstream when the DFU interface is on the FPGA? | 11:56 |
Sarayan | there must be a usb plug somewhere | 12:06 |
xiretza[m] | the fomu is basically ALL USB plug :D | 12:06 |
xiretza[m] | ikskuh: I think you just need to make sure you always flash a working DFU, or you have to fix it via SPI | 12:18 |
ikskuh | /o\ | 12:21 |
ikskuh | okay, that was my guess, but wanted to make sure before i do stupid things | 12:21 |
xiretza[m] | you'll probably be fine if you only use their toolchain, but if you want to use it freely I'd just solder an SPI flasher to it | 12:22 |
ikskuh | right. i guess i'll stick to their toolchain then | 12:23 |
ikskuh | also not sure what to do with it except for having a RISC-V cpu to play around with | 12:24 |
xiretza[m] | yeah, it doesn't exactly have great IO options :p | 12:24 |
ikskuh | ^^ | 12:25 |
ikskuh | i'm going on vacation and i noticed it's still plugged in my usb port, so it seems like i'm taking the FOMU to the netherlands | 12:25 |
ikskuh | kinda fun to have a tiny computer in the always-on-port | 12:26 |
*** emeb_mac <[email protected]> has joined #yosys | 12:27 | |
grmbl | ikskuh: i grabbed an orangecrab | 12:48 |
grmbl | didn't do anything with it yet, but the orangecrab and the ulx3s make for more interesting projects imho | 12:49 |
* qball dug up an 4 year old encrusta (enclustra) pe1 board with an xu5 to play with. | 12:49 | |
ikskuh | grmbl: i got a ECP5-EVN board, Mach-XO, Mach-XO2, Mach-XO3, and a DE-MAX10 :D | 12:51 |
ikskuh | i have plenty of stuff to play with, the FOMU was basically plugged into my laptop and someone said: "it's yours now, have fun" | 12:51 |
qball | I got boards, but little time. | 12:51 |
ikskuh | qball: exactly! | 12:51 |
ikskuh | but i got something even more important now: motivation! | 12:51 |
qball | also got a huge virtex ultrascale+ | 12:51 |
qball | 180mbyte bitfile.. or so | 12:52 |
ikskuh | holy moly | 12:52 |
qball | haveit for 3 years now, not even turned on | 12:52 |
qball | I do have tons of 7020 in use | 12:52 |
ikskuh | the other problem i have is that i have an aversion on PCB drawing | 12:53 |
ikskuh | no idea why | 12:53 |
ikskuh | i just … don't do it, even if i want to | 12:53 |
grmbl | encrusta :D | 12:54 |
grmbl | qball: how many LUTs ? | 12:54 |
qball | (sorry not their biggest fan). | 12:54 |
grmbl | no the biggest fan of what ? x*linx ? | 12:54 |
qball | enclustra | 12:55 |
qball | the 206 gb vivado install also did not make me happy with xilinx :-/ | 12:55 |
ikskuh | yosys is so smol | 12:56 |
grmbl | i deal with xilinx for a living | 12:57 |
grmbl | i am _not_ happy either | 12:57 |
grmbl | and their non-vivado tools aren't good either, cf Vitis (bleeech) or Petalinux | 12:58 |
qball | vu9p by the looks of it. | 12:58 |
qball | hmm I see somebody damaged a pin header.. fun | 12:59 |
qball | luckely nothing serous. | 12:59 |
grmbl | are these the ~50k€ ones ? | 13:01 |
qball | no, not that bad | 13:19 |
qball | 10k I think university price | 13:19 |
