6.6Updating U-Boot

To update the U-Boot, place the image in the RAM (address 0x1000000 in this example) before copying it to the SPI flash.

The following procedure will replace the image in SPI bank 0:

1.Disable SPI write-protect in FPGA register PLD Write Protect and I2C Debug Register.

2.Ensure FLASH_WP_N in SMT Configuration Switch (S2) is in the "OFF" position.

3.Select SPI flash # 0:
