 Tristan Ross | Of the PHDR? | 06:01:03 |
| Tristan Ross | ls works so presumably, it should look like this:

 Mic92 | But i am not super familiar with virtual addresses on RISC-V to be honest. So i don't which adresses are acceptable on that architecture. You should consult the RISC-V os spec | 06:02:33 |
| Tristan Ross | Oh... | 06:02:44 |
| Mic92 | Maybe for now compare it with other binaries | 06:03:16 |
| Mic92 | And it's also hard to read for me. You want to look at what load addresses are requested | 06:05:14 |
| Mic92 | Is riscv 4k page aligned. Usually the first page should not be mapped in userspace | 06:06:27 |
| Tristan Ross | When I updated bootstrap-tools on my clone, I got awk to work and it works with this:

So maybe the virt addr PHDR isn't as important
| 06:06:33 |
| Mic92 | * Is riscv 4k page aligned? Usually the first page should not be mapped in userspace | 06:06:36 |
| Mic92 | Not sure if this is your thing, but llms are pretty good at having read all of the cpu architecture specs and have found in the past for me pretty quickly oddities in readelf. | 06:09:20 |
| Tristan Ross | I've been rubber ducking ChatGPT since Sunday with this problem | 06:09:44 |
| Tristan Ross | It believe AppArmor is the problem, despite me disabling it thinking that was the problem | 06:10:10 |
| Mic92 | Feels unlikely. | 06:10:53 |
| Mic92 | You would see the audit log in dmesg | 06:11:16 |
| Tristan Ross | Yeah, which I don't but ChatGPT is just confident it's AppArmor lol | 06:11:33 |
