  • Clarify OAK Som Pro Boot modes.

Hi

I'm trying to reconcile the schematic for the oak som pro boot modes. The mode shown in the schematic doesn't match any described in the datasheet. Which is correct and I assume if it is used via USB connection that the USB boot mode should be selected.

Schematic:

Data sheet:

    Hi PeterMilani
    I fail to see where discrepancy is.
    USB boot should be 0x16 or 4-0: 10110, GPIOS at 63-59. That's what the MX datasheet says and what the boot schematic shows.

    Thanks,

      Hi @jakaskerl

      The schematic (from the OAK 4P FFC) shows that:

      BOOT0, Pulled up, 1

      BOOT1, Pulled up, 1

      BOOT2 Pulled Down 0

      BOOT3 Pulled Down 0

      BOOT4 Pulled Down 0

      that gives me 00011, which are bits 4:0 what part am I not reading correct?

      cheers

        I see. The primary way of booting for FFC-4P is via SPI (memory) because the device can be booted with a bootloader as well and there is no way to change that if boot was hardwired to 0x16 USB boot.

        The mode checks flash memory for boot "sequence" and if a USB header is flashed, it boots into USB mode. It's part of custom FW.

        0x16 should still work as expected.
