Hi,
I have a problem of Windows Embedded Compact 7 on TMDSEVM3530 (OMAP35xEVM board).
I' ve built and downloaded run-time image (Release mode) to the board, but after downloading the image, nothing displays on the LCD.
The backlight is on, but the desktop picture of Compact 7 doesn't appear. (It seems that the system holds up)
This Problem also occurs when I boot from SD card. In the SD card, MLO, EBOOTSD.nb0 and NK.bin files have been written.
I think that there is some problems in NK.bin file, because a test described below was successful. (Booting from SD card)
MLO, EBOOTSD.nb0 <----- created in Compact 7 Project
NK.BIN <----- CE 6.0 R3 Demo file （the attachment of TMDSEVM3530)
Here is terminal logs of the tests using NK.bin of Compact 7 and CE 6.0 R3 Demo.

Also, I've built successfully in Debug Mode by modifying the memory allocation as below. ("successfully " means no errors)
[Before Modification]
MEMORY
; Name VA Length Type
ARGS 84000000 00001000 RESERVED ; 4K
#if (defined BSP_DSPLINK || defined BSP_TI_DVSDK)

[After Modification]

#if (defined BSP_DSPLINK || defined BSP_TI_DVSDK)

RAM 90F00000 03100000 RAM ; 49MB
However, after download run-time image to the OMAP3530 board, there is an exception as below,
First-chance exception in NAND.DLL.
(0xC0000005: Access Violation)
This exception occurs in "C:\WINCE700\platform\ti_evm_3530\SRC\DRIVERS\BLOCK\NAND\fmd.c"
Are there any problems in NAND driver in BSP of "ti_evm_3530"?
Before building, I deleted drivers for OneNAND from the Catalog file and added those for NAND to that file instead because the board has 256MB NAND flash only.
What causes these problems and what should I do to work around them?
