Greetings!
It has been a while (at least 2 years) since I used my n900. Recently I bought a new (used, obviously) device, and I thought I'd like to try Leste on it.

I found out that I had already forgot much more about how to set the n900 up, and was too lazy to read all the stuff again, so I just used the trial and error way. Finally I got device flashed, CSSU testing installed, U-boot and power kernel installed, leste entry for u-boot done and latest leste image (maemo-leste-1.0-armhf-n900-20220206.img.xz) written to sd.

But when I pick Leste from U-boot, the screen just blacks out just after printing the "booting kernel..." or "starting kernel..." or whatever it says. Do you have any easy explanation what I am doing wrong?
