ZCU-102 boot from USB (DFU)

Hi,

 

We are going to use Zynq Ultrascale+ MPSOC on our board, and we are going to use eMMC for storage and for booting, but we'd like to do the first boot from USB.

Right now I would like to test the procedure with ZCU-102, but there are not many details about it in the documents.

1. Is it possible to boot from USB with ZCU-102? (It does not appear in the user guide)

2. How am I enable DFU in the FSBL?

3. I will be glad if someone can share with me his experience of booting from USB

 

Thanks

 

Avner

Hi @avner

 

At least, U-boot supports to boot from USB flash and eMMC.

So you can build what you want to do, if my understanding is correct.

 

Also, you need enable "USB driver" and prepare dtb for supporting USB.

 

Best regards,

Thanks,

 

But I am asking about the first boot - if I have board after manufacturing, I would like to avoid JTAG

and use USB DFU to first write the software to the eMMC

Hi @avner

 

I'm not sure, but maybe no.

Because of FSBL is very simple program and it's for loading SSBL.

 

However, if you describe some code with hook function in FSBL, it might be able to it...

 

Best regards,
