     180== VN8 Low GSC Battery Voltage Causes Board Not to Power On
    181181

    185185
    186186Workaround:
    187 
    188  * Disable GSC R0.7 so that a CPU reset (as in a U-Boot reset command, a Linux shutdown command, a Linux reboot command, and a CPU watchdog reset) only performs a warm boot and not a cold boot. One way to easily adjust this bit is with a i2c command in the bootloader as follows:
    189 {{{
    190         i2c dev 0 && i2c mw 0x20 0 1 && i2c mw 0x20 0x1f 0xa1
    191 }}}
    192187 
    193  * Note if the board is in this non-powered condition, the GSC battery can be removed to allow the board to be re-powered and gain access to the bootloader
    194 Resolution:
    195 
    196  * For affected products, a GSC firmware update will be issued in the future which defaults this bit to warm boot. This update is recommended for all Venice board revisions.
     188 * Remove the GSC Battery
     189
     190Resolution:
     191
     192 * This will be resolved in future hardware revisions. For affected products, a GSC firmware update will be issued in the future. This update is recommended for all Venice board revisions.
