Linux/AM5728: No data in devicetree.txt of Pinmux Tool

Hello,

We tried to explain that in the heading comments of the file, see below:

/**
 *
 * \brief This file should only be used as a reference! This file contains
 *  register configuration information for the AM57xx Control Module. Two
 *  formats are provided in this file. The device tree (.dts) format WHICH 
 *  MAY CHANGE BETWEEN LINUX KERNEL VERSIONS and a generic format. For 
 *  summarization and description of the pad register bits refer to the
 *  "Control Module" chapter of the device Data Manual. This file should only
 *  be used as a reference. Some pins and/or peripherals, depending on your
 *  use case, may need additional configuration. Only MMC modes are exported
 *  here. All other pad configuration must be done by u-boot. 
 *
**/

Basically, this file is meant to export the "runtime" configuration of only MMC and in some cases DCAN. All other peripherals are configured elsewhere using the other PMT export formats.

Hope it helps,

thanks

Alex

Hello,

Check this app note, it explains the iodelay configuration and pinmux export files types well enough:
