Environment Storage
-------------------
-There are two targets for mx28evk:
+There are three targets for mx28evk:
+
+"make mx28evk_config" - store environment variables into MMC
+
+or
-"make mx28evk_config" - store enviroment variables into MMC
+"make mx28evk_nand_config" - store environment variables into NAND flash
or
-"make mx28evk_nand_config" - store enviroment variables into NAND flash
+"make mx28evk_spi_config" - store enviroment variables into SPI NOR flash
Choose the target accordingly.
factory. It comes with an empty slot (U23), which allows the insertion of a
48-pin TSOP flash device.
-Follow the instructions from doc/README.mxs to generate a bootable SD card.
+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.
-Insert the SD card in slot 0, power up the board and U-boot will boot.
+Follow the instructions from doc/README.mxs to generate a bootable SD card or
+to generate a binary to be flashed into SPI NOR.
