    336 == VENTANA HW20: 16bit YUV HDMI capture not supported
     336== HW20: 16bit YUV HDMI capture not supported
    337337Issue:
    338338 * The GW551x-C is missing HS/VS/PCK/DE signalling and can not capture HDMI video in 16bit synchronous mode.

     351== HW21: 1st Generation QCA 802.11n PCIe devices may not enumerate properly
     352Issue:
    353353 * Recent revision Ventana boards with PCIe bridges may not enumerate 1st generation QCA 802.11n PCIe devices properly resulting in devices showing up as VendorID 0x168c and DeviceID 0xff1c. This has been observed on AR9280 (168c:002a) and AR9285 (168c:002b) and is caused by the PERST# line being de-asserted on power-up before PCIe clock is stable. Even though PERST# is later asserted and de-asserted these 1st generation QCA 802.11n PCIe devices can get stuck and not complete their initialization.

     374== HW22: FLASH geometry layout change
     375Issue:
     376 * End of Life of the 2GB NAND FLASH device used on Ventana GW5xx4 board models has caused a change to a different FLASH device that has a differing block size. The change can cause a code change in the bootloader as well as an update to the Gateworks {{{jtag_usbv4}}} JTAG programming software.
     377
     378Work-around:
     379 * Use the Gateworks 2017.05 Bootloader branch or newer
     380 * Use the latest {{{jtag_usbv4}}} programming software
     381 * Create binary FLASH images with a 2K block size (use the 'normal' FLASH geometry images instead of the 'large' FLASH geometry images).
