Indeed, if you changed the flash for the v14 VIM2 board, please: - move arch/arm64/boot/dts/amlogic/meson-gxm-khadas-vim2.dts into meson-gxm-khadas-vim2.dtsi leaving only the root compatible, model and the v12 spi flash model&size into the meson-gxm-khadas-vim2.dts file - add "khadas,vim2-v14" to amlogic board bindings - introduce a arch/arm64/boot/dts/amlogic/meson-gxm-khadas-vim2-v14.dts file adding the changes (spi flash change, MCU) with a different root compatible & model Neil > >> 2) max-frequency is 104Mhz > (note to self: according to the w25q16 datasheet it supports a maximum > clock frequency of 104MHz, so this is fine) > > > Best regards, > Martin >
