TDA2P-ACD: QSPI support for QPI, DTR and I/O commands

Part Number: TDA2P-ACD

I want to speed up our boot process which uses a QSPI flash (IS25WP256D).

The QSPI flash supports some options for my goal, but I am the impression that the TDA2Px SoC cannot take use of them.

So, I would like to know if the TDA2Px's QSPI subsytem supports:

1) DTR (Dual Transfer Rate)

2) QPI mode (all communication takes place over 4 data lines, including commands)

3) AX read operation

Thanks in advance,

Regards,

Alexander

Hi,

Are you using Vision-SDK Bios? or Vision-SDK Linux?

Thanks

Hi Gaviraju,

we are using Vision-SDK TI-SYS/BIOS

PS. I don't think that my question is software related but hardware related.

Hi Alexander,

TRM does not talk about any of the features mentioned in this thread. Most likely these features
aren't supported.
In any case i will check with the QSPI experts and get back in couple of days.

Best Regards,

Hi Alexander,

Checked with QSPI expert as well. I have a confirmation that none of the features are supported.
Please resolve this thread if you have no further questions.
