AM3505: FW could not run from AM3505 Nand flash after flashing by Flash tools

Part Number: AM3505

Tool/software:

Hello,

Recently, we use the flash tool v1.6 to download the firmware to nand flash. we use the default config file AM35xx (Micron). the size of Nand is 128MX16B (MX30UF1G16AC), and RAM 2Gb (2X1Gb DDR2 SDRAM ). The flash tool said it program success but the xloader didn't run. There is no print information from the serial port. 

The log of erasing in flash tool can display right type of nand. 

can someone know this and help us on this issue?  or if there is any other programing solution in Windows platform, please share with me. 

It is an urgent case. 

Thanks,
