How to use additional UART(D and E) on Colibri i.mx6 under WEC7?

have referred below articles, but still confused on how to add registry entry to active additional UARTD and UARTE under WEC7 on Colibri i.mx6.

anyone can help on this?

based on colibri i.mx6 and eva board and freescale i.mx6 silicon datasheet and below developer article, have solved this issue by adding below registry entries for UARTD.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\COM4]
“Order”=dword:00000002
“IoLen”=dword:000000d4
“IoBase”=dword:021f0000
“Index”=dword:00000004
“DeviceArrayIndex”=dword:00000003
“Prefix”=“COM”
“Dll”=“csp_serial.dll”

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\COM4\Unimodem]
“DevConfig”=hex:10,00,00,00,05,00,00,00,10,01,00,00,00,4B,00,00,00,00,08,00,00,00,00,00,00
“DeviceType”=dword:00000000
“Tsp”=“Unimodem.dll”
“FriendlyName”=“COM4 UNIMODEM”

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\COM4\Pinout_Default]
“colibripin_165”=“altfn=3”
“colibripin_167”=“altfn=3”

it’s similar to UARTE, just modify corresponding IoBase “21F4000” and Pinout.
