v14 v15 178 178 179 179 [=#VN8] 180 == VN8 GSC Battery Voltage180 == VN8 Low GSC Battery Voltage Causes Board Not to Power On 181 181 182 182 Issue: … … 185 185 186 186 Workaround: 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 0xa1191 }}}192 187 193 * 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 189 190 Resolution: 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. 197 193 198 194 Affected Products:
