This step is to copy the SD card uboot files onto the xSPI.

So, there are 2 boot switch settings in this step2.

The SD card is used to boot first, then the xSPI switch is used.

1st time Boot Switch setting:

#EVM to set SD Boot Mode, refer /psdk_rtos_auto/docs/user_guide/J7_EVM_SETUP.html

SW8[1-8] = 1000 0010

SW9[1-8] = 0000 0000 <--Rio: Read EVM user guide

SW3[1-10] = 0110001001

Commands:

When in uboot prompt, do these. (Do this on the EVM!)

sf probe

fatload mmc 1 ${loadaddr} tiboot3.bin; sf update $loadaddr 0x0 $filesize;

fatload mmc 1 ${loadaddr} tispl.bin; sf update $loadaddr 0x100000 $filesize;

fatload mmc 1 ${loadaddr} u-boot.img; sf update $loadaddr 0x300000 $filesize;

After doing those actions above, do this:

1. Turn off the board.
2. Change the dip switch settings to xSPI as below:

2nd time Boot switch setting:

#EVM to set xSPI Boot Mode

SW8[1-8]: 1000 0010

SW9[1-8]: 0011 0000

SW3[1-10]: 0111 0010 10

After this point, do not change the SW8/SW9/SW3.

Now, hereafter, you only can use this setting, no need to change again.
