This BSP provides a basis for development, deployment and execution of Linux based applications on the phyCORE-AM57x System on Module (SOM). For detailed information on the various software components included in the release and how to use them, please refer to the Quickstart.
|
This BSP releases supports the phyCORE-AM57xx Rapid Development Kit (RDK) and also allows configuration options for different SOMs to be used with the RDK carrier board (PCM-948). By default, only the standard kit configuration will be in the table. If you have a different SOM, use the filters below to search by the SOM part number. The U-Boot defconfig and kernel device tree file names are important when creating custom U-Boot and Linux kernel images outside of Yocto development, or modifying Yocto source for further use.
|
This is a summary of how the device tree files and the various includes are broken down, using the am57xx-phycore-rdk (minimal configuration) as an example.

[1] It may be possible to change the software configuration to utilize this interface even if it is not being set in the board's default configuration.
[2] Only enabled on AM5728 silicon variants
[3] Only enabled on AM572x silicon variants
[4] Only enabled with the PCM-057-40A00111I configuration, but would be possible with other PCM-057-xxAxxxxxx variants.
Workaround: prevent frequency changes by disabling the CPUFREQ_DT in the kernel menuconfig, or remove the following code block from the am57xx-phycore-common.dtsi file:
&cpu0 { vdd-supply = <&smps12_reg>; }; |
This is a temporary fix and should be resolved with the next release.
