The sd card slot on picocalc’s mainboard only supports spi mode. I set the spi max freq to 40Mhz in dts. The write speed of the lexar sd card is about 2.3MB/s.
The tf card slot on luckfox lyra supports sdio mode. The max bus freq is 52Mhz in dts. The write speed of mkfounder’s pslc card is about 21MB/s
The new image is uploaded. mmcblk3 is the sd card slot on PicoCalc.
Right shift key is mouse mode toggle key in new kbd driver. Arrow keys control mouse move and square bracket keys control mouse button.
Mouse mode should be useful in pico8 editor.
