Note:
If you cannot connect to the Board Update Portal, refer to the readme.txt file under
<package rootdir>\factory_recovery directory on how you can recover the factory
build.
2.4.2. Step 2: Update the User Software Portion
To update the user software portion of flash memory on your board, follow these
steps:
1.
Prepare your software image and change it to the user_flash.flash file with
the elf2flash utility. Make sure that the "--reset" option is set to Flash memory
base address + Reset Vector Offset (0x0083_0000).
2. Perform the steps in Step 1: Connect to the Board Update Portal to display the
Board Update Portal web page.
3.
In the Software File Name field, specify your user_flash.flash file.
4. Click Upload.
5. Reprogram the user dual configuration image into Configuration Flash Memory
(CFM).
• Image 0: BUP A build
• Image 1: User Nios II processor-based build
• Make sure the user Nios II processor-based build boots up from the reset
vector offset "0x0083_0000".
6. Power off the board.
7. Change the SW2.2 to the OFF position (1) to make sure that it boots up from
image 1.
8. Power on the board.
The new user software image and user hardware build are now running in the FPGA.
