Webb8 mars 2024 · To understand what the Linux driver is doing, I need to attach a logic analyser to the SDIO bus. This isn’t easy on most boards; the interface runs very fast (up to 50 MHz) so the only means of attachment is by soldering onto extremely small surface-mount components, that can easily be damaged. Webb26 juli 2024 · it uses HDMI, Ethernet, SATA, PCI Express, USB, Thunderbolt, or other high speed interfaces for the fast data transfer; the circuit consists of several sub-circuits connected to each other through high speed interfaces (LVDS, DSI, CSI, SDIO, DDR3, etc.); the time of signal propagation over the track is at least ⅓ of the signal rise time;

Using a pull-up resistor which sets a logic 1 limits the maximum transfer speed of the bus which is why the high-speed mode at a speed of 3.4 Mbit/s is introduced. It can be switched by the master which will first transmit a high-speed signal while in low-speed mode (eg. fast mode) few online
