AM3352: Connecting a serial NOR Flash to SPI0 and booting the device

Hello Astro, 

Thank you for the Query.

I can have a look at the schematics to understand the query better. 

Is you query on the hardware connection or the software changes.

Hello Astro, 

Can you please reply the above query. I copied the same below

Hi,Sreenivasa

I have sent the circuit diagram to your private message, could you please check it?
I want to handle it with software. If that is difficult, we are considering hardware support.

Thanks,
Astro

Hello Astro

I had a quick look at the issues you mentioned and the circuit diagram.

The inputs could be floating during powerup causing this issue.

Can you please try terminating the CS using a resistor.

Hi, Sreenivasa

Do you mean "place an external pull-down resistor"? If so, I would like to know about:
1. Is it not possible to pull down in the SOC?
2. External pull-down resistor value

Thanks,
Astro

Hello Astro

2. External pull-down resistor value

If it is required to be pulled down during power-up, an external termination is expected to be used.
