OMAP-L138 Golden Image

Other Parts Discussed in Thread: OMAP-L138

Greetings,

I have a bare-metal application running on an OMAP-L138 which loads and runs from flash memory at power enable.  Is there a way to program a fall-back “golden” image which will automatically load and run if the primary one is corrupted?

Thanks,

Clay

    Clay,

    You may need to do this with the external circuitry may be FPGA or microcontroller to monitor the power good signal from the OMAP-L138 device (RESET OUT), if you don’t get the RESET OUT with the appropriate amount of time you can reset the entire device and set the different boot options through FPGA or MCU, remember the FPGA or MCU needs to be power on first and act as a system monitor.

    You need to program the FPGA or MCU to set the redundant boot options, watchdog and enable the appropriate device chip select for the secondary boot.

    Regards

    Antony,
    Thank you for the quick response and detailed explanation. I'll review this information with our systems
    engineers to see if we want to re-architect part of the system to provide this system monitor functionality.
    Thanks again,
    Clay
