JasonSpangler Posted October 4, 2022 Posted October 4, 2022 Is there a method to boot with BSP kernel (the 4.4 kernel supplied by Rockchip/Radxa) on an existing install (jammy) to compare power usage to mainline kernel (5.15.y current or even 5.19.y rolling)? I tried using the switch kernel support in armbian-config, but the linux-image-legacy-rockchip64 4.4.213-rockchip64 just hung during early boot and had to recover to linux-image-current-rockchip64 5.15.69 . P.S. This is related to my question on the Radxa forums about reducing Rock Pi 4 B+ power usage. 0 Quote
