IMXRT1060 FLEXSPI2 Ball names

[Daniël_Kunst]

I was looking on how to map all my functions on the available pins. In the Reference Manual (IMXRT1060XRM.pdf Rev. 1, 05/2022) in table 10-1 I can see what functions can be mapped on what pins. When I look at the FlexSPI2 A or B (page 300), the table states they can be mapped on "GPIO_SPI_Bx_xx" pads. But according to the datasheet there are no pins named "GPIO_SPI_Bx_xx". There are only GPIO_AD_B0_xx, GPIO_AD_B1_xx, GPIO_B0, GPIO_B1, GPIO_EMC, GPIO_SD_B0 and GPIO_SD_B1 pins. So on what pins can they be mapped then?

Hello,

I had a similar question a few days ago. I have got the following answer:

Which chip you are using? RT1064 or other RT1060?
If RT1064, your reference manual is correct:
https://www.nxp.com/webapp/Download?colCode=IMXRT1060XRM
If RT1061,RT1062, please refer to this reference manual:
https://www.nxp.com/webapp/Download?colCode=IMXRT1060RM
You also can refer to this RT1060, RT1064 migration AN:
https://www.nxp.com.cn/docs/en/application-note/AN12290.pdf

GPIO_SPI_xx_xx is the internal signal, not fanout, to the RT1064, it is used for the internal QSPI flash.
To the RT106X not RT1064, you can consider it is not used. That's why your CFG can't selet it.

It seems that the reference manuals for the RT1061, RT1062 and RT1064 should be merged into one reference manual (IMXRT1060XRM) but the table is not clear on which pads are possible with which processor type. The term "CFG" in the answer above is the MCUxpresso Config Tool - you can use it so cross-check which pins are available. There I also have seen that you can't select GPIO_SPI_xx_xx for the RT1062.

Kind regards,

Stefan

Hello
Hope you are well.
NVCC_SPI power domain is available at RT1060X, RT1060 does not have that power rail.
I suggest you check the part number you have to choose the corresponding datasheet from the product page.
Additionally, there are also two versions of the reference manual.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
