| shenki | shorne: did you make any progress booting linux? | 01:25 |
|---|---|---|
| shenki | shorne: the soc has ram mapped to 0x4000_0000, so I don't see how loading it to 0 will work | 01:26 |
| shenki | shorne: do we need to adjust the soc, or adjust the kernel? | 01:26 |

| shenki | we can adjust the soc by bulding '--cpu-variant linux', which changes the memory map to place RAM at 0x0 | 02:23 |

| shorne | shenki: No luck yet, the tftp issue is fixed, then there was the mapping issue, but linux already maps too 0x0 with mor1k | 11:36 |
| shorne | we can see that there: https://github.com/enjoy-digital/litex/blob/master/litex/soc/cores/cpu/mor1kx/core.py#L34 | 11:37 |
| shorne | So I think we are mapped correctly, | 11:37 |
| shorne | did you have any luck? I am using the mainline kernel, which at the end of last night I noticed has a differnt .dts setup compared to litex (i.e. uart is at a differnt address) but changing that didn't help either | 11:38 |
| shorne | I am going to try the litex branch now | 11:38 |
| shorne | trying https://github.com/litex-hub/linux/tree/litex-mor1kx | 11:43 |
| shorne | That doesn't seem to work either, same issue, Liftoff then no response | 11:51 |
| shorne | I will try again with litex-buildenv and mainline thats what I had been using before | 11:52 |
| shorne | just to confirm I am sane | 11:57 |
| shorne | OK, litex-buildenv with upstream kernel works just fine | 12:07 |
| shorne | litex-boards with the litex-hub/linux/tree/litex-mor1kx branch doesn't seem to work | 12:07 |
| shorne | I sent a mail to mateusz, hopefully he can explain which branches he is using then we can bisect | 12:34 |
| somlo | shorne: would you mind trying https://github.com/litex-hub/linux/tree/litex-rebase ? I has the latest of everything I'm aware of (except vex/mor1k specific defconfigs) | 13:44 |
| somlo | s/I has/It has/ :) | 13:45 |
