Part Number:OMAP-L138
I'm using a OMAPL138 processor board. I have 2 different board. The electrical circuit for the first board is on the pictures
The electrical circuit for the secondt board is on the pictures
I booting both boards the processor OMAP-L138_FlashAndBootUtils_2_40 utility by UART2 interface. I booting *.ais file to NAND flash. I download OMAP-L138_FlashAndBootUtils_2_40 utility from https://sourceforge.net/projects/dvflashutils/files/OMAP-L138/v2.40/.
Furser, I set the boot pins to UART2 boot mode. And I enter command in the console for erasing NAND flash: sfh_OMAP-L138.exe -erase -targetType OMAP-L138 -flashType NAND -p COM4 -v.
I see on the console log for first board

Furser, I looked with an oscilloscope NAND port pins on second board and I don't looked timing diagramm for NAND flash. All processor pins for NAND is set 3.3V. But, I'm look correct timing diagramm on oscilloscope for first board.
What is the problem?
