Peripheral SDIO[edit | edit source]
AXEL Lite SOM provides up to three SDIO interfaces; due to PINMUX restrcitions and usa of the NAND controller onboard, a typical usage on AXEL Lite SOM is the following one:
- SD1 configured in 4-bit mode and used as boot device (with BOOT_SEL)
- SD2 configured in 4-bit mode
- SD3 configured in 8-bit mode: a typical connection for this interface is forx interfacing an external eMMC storage device
Description[edit | edit source]
The SDIO interface available on AXEL Lite is based on i.Mx6 SoC.
The SDIO port supports the following standards and features:
- 1-bit or 4-bit transfer mode specifications for SD and SDIO cards up to UHS-I SDR-104 mode (104 MB/s max)
- 1-bit, 4-bit, or 8-bit transfer mode specifications for MMC cards up to 52 MHz in both SDR and DDR modes (104 MB/s max)
- Compatible with SD Memory, miniSD Memory, SDIO, miniSDIO, SD Combo, MMC and MMC RS, embedded MMC and embedded SD cards
- Up to 200 Mbps data transfer for SD/SDIO cards using 4 parallel data lines
- Up to 416 Mbps data transfer for MMC cards using 8 parallel data lines
- Up to 832 Mbps data transfer for MMC/SD cards using 8 parallel data lines in DDR mode
- Dual internal 32x32-bit FIFOs
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
