Updating 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 CPLD register
PLD Write Protect and I2C Debug
2.
Ensure FLASH_WP_N in SMT configuration switch (S2) is in "OFF" position.
3. Select SPI flash # 0:
sf probe 0
4. Erase 0x90000 bytes starting at SPI address 0:
sf erase 0 0x90000
5. Write 0x90000 bytes from RAM address 0x1000000 starting at SPI address 0:
sf write 0x1000000 0 0x90000
To replace the image in SPI bank 1, replace step 2 with "Select SPI flash # 1:"
sf probe 1
