Config Tools for i.MX v8

[saidjazouly]

Hi NXP,

we have a question about the Config Tools for i.MX8, in the generated dts file we can see that some Pad Control Register values have their Reserved bit fields set:

for example: MX8MM_IOMUXC_SAI2_TXFS_UART1_DCE_CTS_B 0x00001816

1. Is this a bug in the Config Tools?
2. Can the reserved bit value be ignored and not being set? For example:

using:

MX8MM_IOMUXC_SAI2_TXFS_UART1_DCE_CTS_B   0x16

instead of:

MX8MM_IOMUXC_SAI2_TXFS_UART1_DCE_CTS_B   0x00001816

Regards.

Hi saidjazouly ,

>>Is this a bug in the Config Tools?

      No, this is not.

      For reserve bit, whether you set it, it is useless.

   >>Can the reserved bit value be ignored and not being set?

    Yes , it can.

     you don't need to configure it.

Hope this information is helpful to you.

Have a nice day!
