DLPC200: DownloadBPPfromFlashToExtMem(0x0030) command via SPI does not display expected image

RY9983

Part Number: DLPC200

Hello.

I have a question about DownloadBPPfromFlashToExtMem(0x0030) command of DLPC200.

When I send the command via SPI, the expected image does not display.
Do you have any advice to display image appropriately via SPI?

Case-a) I am sending following command via SPI and Write Resp returned with no error.
Tx Command: 02AA0000 0C00 3000 0000 00000400 00800100 (WriteResp : 03AA0000 0200 0000 02)
(This command was generated by LightCommander Log "DLP_Img_DownloadBitplanePatternFromFlashToExtMem 0x00040000, 98304, 0")

Case-b) When I send via USB by LightCommander GUI "Command Line Window", Light commander works as expected.

Hello RY,

Paul has changed roles and I will be working with you on this issue. I now have one of our few remaining LightCommander units set up in the lab to see if we can recreate this issue here and come up with a solution.
