iMX7ulp dev board SAI using

ATAineri — Fri, 24 Jan 2020 18:08:19 GMT

I'm going to design iMX7ulp based Hi-Fi audio device, but there is no free SAI on iMX7ulp EVK board. Moreover, I can't find information in iMX7ulp reference manual about what pin can I reassign to provide SAI pins out.

I can't find a table like it was in iMX6ul reference manual:

How can I use SAI on iMX7ulp EVK board? What pins can I reassign? Where is the table of pins mux like it was in iMX6ul datasheet?

Eventually, I can blow out codec on the board and solder the connector I need, but it is the worst variant. If there could be a better solution I will prefer it.

I need one SAI and one I2C to provide my codec to work.

Take a look at the attachments in the Reference Manual. You'll find the PinMux there.

Hi,

The IOMUXC Spreadsheet is mentioned several times in the reference manual but I'm not able to find the attachement.

Can you please provide a link to the spreadsheet?

Thanks!
