I have a custom U500 build, without PCIe. It has only DDR3 memory (4 GBytes) and UART for now.
I already have a mechanism to load the DDR3 with the linux file system.
I would like to boot linux on this and access it using uart, later on move to Ethernet.
To begin, i looked into freedom-u500-sdk, built the standard linux as given by the makefile.
Can anyone point me to a document or reference to enable U500 to boot directly from DDR3.
