Trunk 151 has the same problem.

@Werner OK, since I have a few Duos (v1.0 and v1.1) I tried same Jammy with 6.1.63 kernel SD in each and let idle. The 1.1 with copper heatsink runs about 40C, the 1.1 with same aluminum heat sink runs around 45C. The v1.0 runs around 50C. So weird. I'll try latest build, but stress-ng causing thermal shutdowns worries me. I used to run decent loads on these little boards. Good thing is thermal shutdown works or it would burn up the board.

How can I force it to boot from SD though?

As a followup: hardware crypto is damn slow on the Ky / SpacemIt platform, at least for default LUKS block encryption with AES. This probably also affects the Banana Pi F3 image. With default sector-size of 512 byte, HW-AES is 5 times slower than SW-AES, while cryptsetup benchmark reports 5 times faster. Main reason: block size. With sector-size of 4096 LUKS is reasonable fast. Also there is leftover debug (cannot be switched off) and a small bugs in the driver that triggers SW crypto fallback after HW crypto succeeds.
