is ION size supposed to be set to zero by default for these images? Yes, but requires a custom built fip.bin | 01:41:50 |
| Nick Cao | In reply to @nickcao:nichi.co
Yes, but requires a custom built fip.bin It seems the one we are using already have ION size set to 0: https://github.com/mcdonc/duo-buildroot-sdk/tree/nixos-riscv | 01:43:00 |
| Nick Cao | In reply to @nickcao:nichi.co
Yes, but requires a custom built fip.bin * It seems the one we are using can't have ION size set to 0: https://github.com/mcdonc/duo-buildroot-sdk/tree/nixos-riscv for some reason. | 01:43:27 |
| @atka:matrix.org | perhaps this would work?

Looks so. You can try this simply by rebuilding the fip (in a ubuntu container for simplicity) and replace prebuilt/fip-duo256.bin | 01:52:56 |
| @atka:matrix.org | ok, thanks! i'll try it out | 01:53:24 |
