- FREESCALE MX28EVK
- ==================
- Supported hardware: MX28EVK rev C and D are supported in U-Boot.
- Files of the MX28EVK port
- --------------------------
- arch/arm/cpu/arm926ejs/mxs/ - The CPU support code for the Freescale i.MX28
- arch/arm/include/asm/arch-mxs/ - Header files for the Freescale i.MX28
- board/freescale/mx28evk/ - MX28EVK board specific files
- include/configs/mx28evk.h - MX28EVK configuration file
- Jumper configuration
- ---------------------
- To boot MX28EVK from an SD card, set the boot mode DIP switches as:
- * Boot Mode Select: 1 0 0 1 (Boot from SD card Slot 0 - U42)
- * JTAG PSWITCH RESET: To the right (reset disabled)
- * Battery Source: Down
- * Wall 5V: Up
- * VDD 5V: To the left (off)
- * Hold Button: Down (off)
- To boot MX28EVK from SPI NOR flash, set the boot mode DIP switches as:
- * Boot Mode Select: 0 0 1 0 (Boot from SSP2)
- * JTAG PSWITCH RESET: To the right (reset disabled)
- * Battery Source: Down
- * Wall 5V: Up
- * VDD 5V: To the left (off)
- * Hold Button: Down (off)
- Environment Storage
- -------------------
- There are three targets for mx28evk:
- "make mx28evk_config" - store environment variables into MMC
- or
- "make mx28evk_nand_config" - store environment variables into NAND flash
- or
- "make mx28evk_spi_config" - store environment variables into SPI NOR flash
- Choose the target accordingly.
- Note: The mx28evk board does not come with a NAND flash populated from the
- factory. It comes with an empty slot (U23), which allows the insertion of a
- 48-pin TSOP flash device.
- mx28evk does not come with SPI NOR flash populated from the factory either.
- It is possible to solder a SOIC memory on U49 or use a DIP8 on J89.
- To get SPI communication to work R320, R321,R322 and C178 need to be populated.
- Look in the schematics for the proper component values.
- Follow the instructions from doc/README.mxs to generate a bootable SD card or
- to generate a binary to be flashed into SPI NOR.
