Background:
* I have a custom am5728 board with 4GB of memory.
* Kernel version 4.4 is needed for LPAE to utilize more 4GB of memory. Reference: https://e2e.ti.com/support/processors/f/791/p/552861/2067236#2067236
* The latest (as Aug 19/2020) am57xx Linux-RT SDK version 06.03. builds kernel version 4.19. Reference: https://www.ti.com/tool/PROCESSOR-SDK-AM57X
* The am65xx SDK build kernel version 7.00. builds Kernel version 5.04 Reference: https://www.ti.com/tool/PROCESSOR-SDK-AM65X
* I am normally conpiling using oe config file "processor-sdk/processor-sdk-06.03.00.106-config.txt", and bitbake command "MACHINE=am57xx-evm ARAGO_RT_ENABLE=1 bitbake arago-base-tisdk-image"
* There are commits to the oe-layersetup git repo that provides updated configurations, for example "coresdk/coresdk-07.00.00.005-config.txt". Reference: arago-project.org/.../
My goal is to have Linux access all 4GB of memory. I assume I need to upgrade the Linux kernel.
How would TI recommend building a version 4.4 Kernel or newer (5.04) for an am57xx board?
Thank you for your help.
Greg.
