14:52 <losg> hello guys

14:52 <losg> I'm trying to use litex

14:52 <losg> I should have flashed my FPGA, but I cannot see the device with lspcie.. should I remove the JTAG cable?

14:58 <losg> what I dont get is that if the JTAG attached blocks the execution somehow

15:04 <lkcl> daveshah: we found the last long combinatorial path which was in the DIV FSM, libre-soc's now up to 98mhz on an ECP5

15:05 <lkcl> i say 98mhz: it's still an FSM at the moment so an IPC of around 0.15

16:32 <zyp> losg, what board do you have?

16:32 <losg> a Xilinx device

16:32 <losg> Ultrascale kintex

16:32 <losg> the board is not a development board, or very supported one ahah

23:15 <KSmith> hey guys im wondering if i could get some help again, im attempting to install the nexys4ddr prebuilt onto a nexysa7 using linux-on-litex-vexriscv however when i attempt to upload i come across an error https://pastebin.com/TNnzVj1d since im using virtualbox running ubuntu i though virtualbox was the issue but ive had no luck finding a solution,

23:15 <KSmith> within virtualbox i tried setting up the board as a usb device, when that didnt work i tried as a serial device, then both(virtualbox came up with an error when both refer to the same device). as a usb device ubuntu can see the devices https://pastebin.com/fi6ebcnz i tried searching more about the Error: libusb_open() failed with

23:15 <tpb> Title: Pastebin.com - Potentially offensive content ahead! (at pastebin.com)

23:15 <KSmith> LIBUSB_ERROR_ACCESS and found it may have to do with udev rules so i installed that and no change.

23:42 <somlo> KSmith: I'd try to find some material on how to configure USB forwarding on Virtualbox, seems like that's where your problem might be

23:44 <somlo> _florent_: apparently, on linux, during `litex_mmc_probe()` one must add `mmc->caps |= MMC_CAP_NEEDS_POLL` for eject and reinsert to be recognized by the OS

23:44 <somlo> well, at least in the absence of IRQ capabilities in LiteSDCard :)

23:46 <somlo> after that, I get some horrible-looking errors on re-insertion, but that probably just means there's extra (re)setting that needs to be done on the sdcard (probably via `set_ios()` or thereabouts)

23:47 <somlo> slow (but positive) progress :)
