[Wedge100BF-series] SPI Flash Firmware version checking and upgrade Follow

Purpose:

This is the article for the check and upgrade the SPI flash firmware version on Wedge100BF-series.

Model:

Wedge100BF-32X/65X/32QS

Procedure:

Step 1. Install Diag Utility on Wedge100BF-series and enter Barefoot SDE

Please follow the article to install Diag Utility and enter Barefoot SDE:

[Wedge100BF-series] Install and start up Accton Diag, Barefoot Shell and SDE

[Note] Users can also enter Barefoot SDE through their installed NOS if not convenient to use Diag.

Step 2. Check the SPI Flash version and chip

bf-sde> reg_rd 0 000400D8
0 [000400d8] : 20180416 : __device_select__misc_regs__spi_idcode
            # Report the ID code read during firmware loading from the SPI EEPROM
  [31: 0] 20180416 : spi_idcode
bf-sde> exit
bfshell> exit
root@bfn-switch:~/DIAG-V0.34# lspci |grep 1d1c
06:00.0 Unassigned class [ff00]: Device 1d1c:0010 (rev 10)

If the SPI flash firmware version is earlier than 20180416, please follow Step 3. to upgrade it.

Step 3. Upgrade SPI Flash

Check the IP address 

root@bfn-switch:~# ifconfig enp2s0
enp2s0  Link encap:Ethernet HWaddr 00:90:fb:5f:9b:1c
        inet addr:192.168.1.1 Bcast:192.168.255.255 Mask:255.255.0.0

User could configure IP address as they want.

Transmit new SPI image to DUT via SCP (username/password: admin12/bfn123)

Transmit new SPI image to /root

root@bfn-switch:~# cp /home/admin12/U7_spi_20180416_gen2_sbusclk5.bin /root

Enter bfshell and SDE

root@bfn-switch:~# bfshell

Reboot Diag to finish the installation

bf-sde.bf_pltfm> ..
bf-sde> exit
bfshell> exit
root@bfn-switch:~# reboot

Caution: Make sure "lspci | grep 1d1c" could check the chip before upgrade the SPI flash firmware, otherwise reboot the switch until it could check the chip.
