Reimu NotMoeAs of 2023-08-02, this comment appeared below the CNX software article. It appears to be from a upstream Linux maintainer.
And here are my responses:
- X1501 DO boot the latest 6.5-rc4 kernel using the X1000 target
- It's not our fault as fixes & new drivers of the X1000/X1501 can't be mainlined
- X1501 can't run systemd but it's still awesome with its 18mW standby power usage
- A PSRAM is not a NOR flash
LoShark (tested on X1501 EVB with LoShark's rootfs) running the latest rc kernel (with X1000 as target):
This is the complete boot log. Many things are broken, as expected. But you get a working shell.
