Hello
We made custom board using LS1012A.
We don't need the USB interface, so we conform to the following description in AN5192 (Rev.1).
[AN5192]
Table 3. Power and ground pin termination checklist
Table 31. USB1 pin termination checklist
Now, our board does not bootup.
We face a similar phenomenon when without using USB with LS1012ARDB.
In addition to the hardware design of AN5192, could you advise us the points we should take attention to?
Best Regards,
Hello ,
We notice the mistake in modificating the board.
Sorry, please let me withdraw this question.
Best Regards,
