The ASSP is designed to support a wide range of portable low-power applications such as Wi-Fi / SD Memory combo card, GPS, UW B, camera, Zigbee, RFID, and scanner. Number of wait states according to Cortex-M3 clock frequency 2. Due to clock source & divisor restrictions, it cannot hit 50MHz. Sony PS4 dev kit FCC filing shows off extra ports, 2. 0 are supported. Support a full clock range of 0-400 KHz. 3 I2S clock generator This section describes the I2S clock generator that is dependent on the master clock MCLK (enable or disable), the frame wide, and the I2S peripheral clock (I2SCLK). Also, all SD cards should support at least 25 MHz clock frequency, I've tried with different cards and none seem to work. • Displays clock frequency • Debug SD/SDIO device protocol and timing issues • Non-intrusive capture and analysis • Use with both standard SD form factor. Specifies the clock frequency of the SDIO controller. However interestingly every card I've tried has been in default speed mode (25MHz max clock). RK3308 is a quad Cortex A35 based SOC with rich audio interfaces(I2S/PCM/TDM/PDM/SPDIF/VAD/HDMI ARC), which designed for intelligent voice interaction and audio. Yes, using SDIO is easy to use thanks to PhilE - just add dtoverlay=sdio, poll_once=no to config.
