We have a 4GB SDRAM custom board use micron MT41K512M16HA chip
I compiler kernel with below funtion,
System Type - Full 4GB physical memory support
System Type - Support for the LPAE
Kernel features - Memory split is 3G user / 1G kernel
Hello, nuu9323226: To support 4G RAM in Jetson, you may have to do more than re-configuring kernel. 1. Kernel part 1.1 DVFS table @ arch/arm/mach-tegra/board-ardbeg-memory.c must be updated according the DDR chip used. 1.2 CONFIG_ARM_LPAE must be enabled in kernel configuration. 1.3 Another little patch for ethernet driver @ drivers/net/ethernet/realtek/r8169.c must be applied, otherwise the network may fail to work. 2. extlinux.conf must be changed to add mem and ddr_die, like mem=2048M@4096M, ddr_die=2048M@4096M. 3. BCT with the new DDR chip must be applied during flashing. br Chenjian
the 2GB is working.
when I change kernel parameters,
add mem=2015M@2048M mem=2048M@4096M ddr_die=2048M@2048M ddr_die=2048M@4096M
the boot kernel halt, not running kernel
I don’t update DVFS table&BCT with micron MT41K512M16HA.
How can I upgrade to this?
sorry my english
