Hi,we buy a Spectrum Digital DM816x/AM389x EVM （with daughter card）。That is OK, but one day I typed “ nand scrub ” in uboot，then uboot has a bug. I think that is because nand flash has been cleared all ，so I reload uboot file again in CCS5 following the guide in DVRRDK，as follows:
turn SW3 to all“0”，SW4[10]，open CCS5.2 ，reload the project in host-tools/src/ nand-flash-writer. After rebuild，I reload the nand-flash-writer.out into the board，and start。Then we can see taht:

So Uboot reloads successfully ，then we turn SW3 to [0000010010],and start the board, it goes into uboot. But when we type “nand erase”in uboot ,we get the bug information that :
Also ,I try to save the uboot enviroment，and the bug information goes that :
Then ，it comes a waiting without stop,so I can do nothing。
I also think that I do not have reloaded the right uboot bin ,so I erase all, and reload bellow
E:\my\sharedfiles\DVRRDK_03.00.00.00\pre_built_binary\ti816x_dvr\uboot_NAND_DM816X_EVM
But , the bug information is also here ,this is no chang.
What is the matter ?/ what can I do ? please help me
Thank you !!
Best wishes !
