These patches applied to the 5.4.96 in OpenWrt (98d61b5) work fine so far on an Espressobin v7 AFAICT per changing values in /sys/devices/system/cpu/cpufreq/policy0. Are these changes intended to work @1.2 GHz on the v7? I have the beige case and heat-sinks with paste on the board, and the power adapter is the Fairway for 2.0A. However, the device hangs fairly quickly under load with firmware flashed of the built as below: diff --git a/package/boot/arm-trusted-firmware-mvebu/Makefile b/package/boot/arm-trusted-firmware-mvebu/Makefile index c4669edb52..20899c29e7 100644 --- a/package/boot/arm-trusted-firmware-mvebu/Makefile +++ b/package/boot/arm-trusted-firmware-mvebu/Makefile @@ -72,7 +72,7 @@ define Trusted-Firmware-A/espressobin-v7-1gb BUILD_DEVICES:=globalscale_espressobin-v7 UBOOT:=espressobin DDR_TOPOLOGY:=5 - CLOCKSPRESET:=CPU_1000_DDR_800 + CLOCKSPRESET:=CPU_1200_DDR_750 PLAT:=a3700 endef See: https://github.com/openwrt/openwrt/commit/5fae94d987f2261b148c035130a00350c905a13e
