Sorry I'm having problems when after I get done making a custom bitfile and loading it on my 6i24 board. halcmd session is below and .vhd file is attached.
halcmd: loadrt hostmot2
halcmd: loadrt hm2_pci
hm2_pci: loading Mesa AnyIO HostMot2 driver version 0.7
hm2_pci: discovered 5i24 at 0000:04:00.0
hm2/hm2_5i24.0: inconsistent Module Descriptor for UART Transmit Channel, not loading driver
hm2/hm2_5i24.0:     Version = 0, expected 0
hm2/hm2_5i24.0:     NumRegisters = 4, expected 4
hm2/hm2_5i24.0:     InstanceStride = 0x00000040, expected 0x00000010
hm2/hm2_5i24.0:     MultipleRegisters = 0x0000000F, expected 0x0000000F
hm2/hm2_5i24.0: inconsistent Module Descriptor!
hm2/hm2_5i24.0: failed to parse Module Descriptor 4
hm2_5i24.0: board fails HM2 registration
RTAPI_PCI: Unmapped 65536 bytes at 0x7f066fd2e000
Driver probe function failed!
hm2_pci: error registering PCI driver
hm2_pci: rtapi_app_main: Operation not permitted (-1)

The UART requires odd register mapping that's not accommodated
by the normal IDROM info so you need to set the instance stride in
the top level file:
InstStride1: integer := 64; -- instance stride 1 = 64 bytes = 16 x 32 bit registers sserial
-- InstStride1: integer := 16; -- 4..7 16 for BSPI/UART Ick double Ick

I would suggest not using the UART and rather using the PKTUART instead

I'll try the PKTUART.

great so that loaded. PCW - could you point me to an example of using PKTUART? Basically all I want to do is send the states of pins into a serial stream.

I think there's an example component: pktgyro_test (serial coms with a gyroscope chip)
Unfortunately there in not a current clean way to have a driver with simple hal support
due to the lack of string or array support in hal
