I had product 1000 pieces omap4460 custom boards which used the USB3320,LAN9514 chip, but there have been some problems, 930 piece board is normal, more than 30 pieces, the USB function is exception :
1, booting with usbboot tools, can read CPU ASIC ID, but the result is abnormal.
2, my emmc on the board ,the OS can be start up, but omap4460 communicate with USB network adapter LAN9514 abnormalities.
After our analysis, we doubt that the OMAP4460 SMT have problem, we plant the omap4460 Elpida memory ball, solder omap4460 up again, but the result is as described above.
Please help analysis, thank you!
