    265265No, this feature is not available on any Gateworks SBC.  In most cases using POE will be the most effective method of powering on and off the board with Ethernet.

    267 == I'm using mainline Linux, or do not have a GSC driver.  What do I loose and is there a work around?
     267== I'm using a version of Linux without a GSC driver, what do I lose and is there a work around?

    269269Getting our GSC driver to be adopted by the mainline kernel community has been an up hill battle, hence the long delay in its implementation.  Many of its features are still accessible using I2C commands and other methods:
     
    275275 * http://trac.gateworks.com/wiki/gsc#GeneralPurposeInputandOutputGPIO
    276276 * http://trac.gateworks.com/wiki/gpio
    277 * You can achieve tamper protection using GPIO.
    278  * http://trac.gateworks.com/wiki/gsc#GeneralPurposeInputandOutputGPIO
     277* Linux input event support will be lost, there is currently no work around for this.
     278 * http://trac.gateworks.com/wiki/gsc#GSCInputkerneldriver
    279279* Hardware watchdog, this is where you may run into trouble using GSC, though the CPU watchdog will be adequate in many cases.  The issue here will be the inability for the GSC to disable board power.
    280280 * http://trac.gateworks.com/wiki/gsc#HardwareWatchdog
    281 * Reset monitor, for this you will need a GSC driver.
    282  * http://trac.gateworks.com/wiki/gsc#ResetMonitor
    283 * Software field-upgradable firmware, sysupgrade is available in our pre-release of Gateworks-OpenWrt 18.0x and mainline OpenWrt 18.06
    284  * http://trac.gateworks.com/wiki/OpenWrt/sysupgrade
    285  * Also, you can use TFTP to flash firmware from the boot loader
    286   * http://trac.gateworks.com/wiki/ventana/openwrt#InstallingFirmwareviaSerialEthernetTFTPusingthebootloader
    287   * None of these methods will allow you to update u-boot, or SPL.  This must be done with Jtag, even when the GSC driver is available.
     281* Field firmware updates (via gsc_update tool) do not depend on the gsc driver
