We are developing a custom board that will have only 128Mbytes DDR3L RAM memory. We got the board booting uboot but when booting linux it is not working. The clock we are using is a 100MHz differential clock.
I just took the tower dev kit, removed the resistors frm the clocking circuit so that the config matches my board. In the RCW I config the DDR3 clock to use the differential one and I am able to boot from the SD card After this I just tried booting linux modifying the mem parameter in the kernel command line and as soon as I use a value lower than 512M the kernel stops booting.
Is there any minimum requierement for booting linux in this platform?
