3.3V SD support on RT595

[daisukeyoshinar]

Hello.

I'm considering using i.MX RT595.
Is it possible for i.MX RT595 to access an SD that only supports 3.3V?

I understand that it is not supported by EVK.
I also found the following document.
https://www.nxp.com/docs/en/user-guide/IMXRT500HDG.pdf

P.41
Due to the removal of 3.3 V support on the high-speed pads, the SD card interface is no longer supported.
This considerably reduced the current leakage on VDD1V8. An erratum is issued to describe this further describe.
We are evaluating the use of using an external level shifter to enable this.

Where can I find the evaluation results when using an external level shifter?

Best regards,
Daisuke Yoshinari
