Compile Question:Difference between DM816X_UD_DVR and DM816X_TI_EVM

hi all

basic info:

* DVRRDK_04.00.00.03

* custom dm8168 board

I found that:

when DVR_RDK_BOARD_TYPE:= DM816X_UD_DVR，uboot support the nandflash that is 8-bit buswidth

when DVR_RDK_BOARD_TYPE:= DM816X_TI_EVM，uboot support the nandflash that is 16-bit buswidth

Then I checked the schematic diagram in DVRRDK_04.00.00.03\dvr_rdk\docs\Hardware\ folder，indeed，a 8-bit nandflash is connected to dm8168(K9F2G08U0M)

my question is:

1，Are there other difference in terms of hardware when DVR_RDK_BOARD_TYPE = DM816X_TI_EVM?

2，Are there other difference in terms of software(like linux kernel,mcfw?) when DVR_RDK_BOARD_TYPE = DM816X_TI_EVM?

3， Is there a Hardware schematics according to DM816X_TI_EVM?where i can find it?

sorry about my english.

    Hello,

    For DVRRDK support contact your local FAE. Or you could search in the e2e for similar issues.

    Most probably yes. I am not familiar with the UD_DVR board, I am familiar only with TI EVM board. You can compare the schematics and user guides to track the HW differences between the two boards.

    DM816x TI EVM is using EZSDK, while UD DVR is using DVR RDK. Link to EZSDK:

    The EZSDK comes with old u-boot and linux kernel, the latest versions can be found in the below locations:

    The DVR RDK u-boot and linux kernel are available at the below locations:
