| atka | hello, what are the nixos package equivalents for openbsi and uboot-qemu? trying to run debian risc-v port in qemu on nixos host | 23:54:37 |
| atka | or is there another/better way to play around with risc-v assembly in qemu on nixos | 23:56:12 |
 Alex | Does QEMU not bundle OpenSBI and u-boot (or equivalent) for its RISC-V machines? | 23:59:52 |

| Alex | See https://www.qemu.org/docs/master/system/target-riscv.html#risc-v-cpu-firmware | 00:00:31 |
| atka | qemu-system-riscv64: Unable to find the RISC-V BIOS "/usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.elf" | 00:00:32 |
| atka | oh oops, probably my mistake | 00:01:02 |
| atka | I have the wrong location specified most likely | 00:01:50 |
| Alex | You shouldn't have to specify the location at all if you use -bios default. | 00:02:18 |
| atka | ok, thanks, I'll try that again, was following an old debian guide | 00:02:38 |
| atka | progress, now getting a kernel panic in qemu | 00:09:58 |

| 00:21:32 |
| atka | looks like I need to replace "root=LABEL=rootfs" with another device | 00:31:54 |
| atka | nevermind, figured it out, I specified my kernel but not initrd | 00:38:02 |
| atka | working now, running debian trixie w/ 6.8.9-riscv64! | 00:39:50 |

| atka | anyone play around with those milk-v duo boards yet? I have a few on the way to tinker with. I know nixos/alpine/debian run on them, plus various RTOS like nuttx. | 03:55:09 |
