CarlFKback00:39
xfxfmithro: there were some people experimenting with using SDR to pickup venue mics.  do you know what SDR they were using?  would't mind ordering one00:48
mithroCarlFK: Where are you running that script?00:55
CarlFKmithro:  ~/temp00:55
mithroCarlFK: That won't work - it needs to run inside a HDMI2USB-litex-firmware repo00:55
mithroCarlFK: If you just want qemu without the firmware repo, you need to clone https://github.com/timvideos/qemu-litex.git and then run ./build-litex-qemu.sh00:56
tpbTitle: GitHub - timvideos/qemu-litex (at github.com)00:56
mithrocr1901_modern: ping?00:59
CarlFKmithro: ah, I think I skipped too much.  "You can skip the section requiring the Xilinx tools"01:05
CarlFKmithro: but I am not really sure what section that is01:05
mithroCarlFK: https://github.com/timvideos/HDMI2USB-litex-firmware/blob/master/getting-started.md#prerequisite-xilinx01:05

CarlFKmithro: so I should do this: "Run the bootstrap script to build an environment required for flashing firmware:'  https://github.com/timvideos/HDMI2USB-litex-firmware/blob/master/getting-started.md#bootstrap-hdmi2usb-litex-firmware-and-dependencies01:07

mithroCarlFK: yes01:07
cr1901_modernmithro: pong (I won't be here long)01:11
mithrocr1901_modern: So, where are we with the SPI flash?01:12
cr1901_modernmithro: Exactly where we were yesterday :). It's working, bitbang reading, and upload needs to be added01:13
mithrocr1901_modern: Have you checked it it works on the Opsis too?01:13
cr1901_modernmithro: No. Actually I need to buy a power adapter for the Opsis too, now that you mention it. I haven't powered it on in a while.01:14
cr1901_modernmithro: My next plan was to test w/ minispartan601:14
mithroThe minispartan6 doesn't have working DDR memory01:50
cr1901_modernIt doesn't? I mean, it has DRAM, it's just slow as hell01:51
mithrocr1901_modern: It's currently broken01:51
cr1901_modernAhhh01:51
cr1901_modernI wonder why... hmmm...01:51
mithroCarlFK: Updated instructions at https://github.com/timvideos/qemu-litex/blob/master/README.md01:52

CarlFKmithro: thanks - I'll give that a run01:53
CarlFKmithro: I'm trying the 2nd option because it looked simpler: https://github.com/timvideos/qemu-litex/blob/master/README.md#building-outside-hdmi2usb-litex-firmware02:00

mithroDid you see the lines following that?02:14
mithroCarlFK: If you just want to have something which runs straight away, use the one inside the HDMI2USB firmware02:16
CarlFKmithro: I don't really have a want, other than to test the instructions and scripts02:17
mithroCarlFK: The HDMI2USB firmware one will get you a H2U> prompt02:17
CarlFKk - I'll try that next02:18
CarlFKmithro: 2nd "to use..." qemu-system-or32: /home/juser/temp/tv/qemu-litex/hw/openrisc/litex.c:194: litex_init: Assertion `CONFIG_CPU_RESET_ADDR == 0' failed.02:18

CarlFKmithro: yes.04:43
CarlFKmithro: I am a little skeptical that the 2 vars make things easier.      But I also know that these bootstraping things are hard, so not really sure I know a better way04:45
