I made a PCB based on OMAP-L138 (som-p.zip - our PCB scheme, sch_som_work.zip - working prototype, which running successfully). I configured boot pins to load from UART2. After I connected OMAP-L138_FlashAndBootUtils_2_40 and entered the command sfh_OMAP-L138.exe -erase -targetType OMAPL138 -flashType NAND -p COM4 -v to start erase NAND memory. Here is a log:

After that program is freezes and nothing is happening.
For working prototype log is here (all work fine):

I tried to use oscillograph and have seen that time diagrams on NAND I/O is fine, but on my PCB they all is 3.3V.
What could be the problem?
