We were using imx6qpsabre (1 gb ram ) board before, now we designed a new custom board using imx6q soc and 2 gb micron ddr ram, remainig system is almost same.
I am trying to configure u-boot-fscl and linux-fslc with new ddr ram configuration (it is already booting). I tried to configure u-boot for 2 gb ram using mx6q_4x_mt41j128.cfg file with configuration data of imx stress test tool results. And I changed memory from the device tree. But I cannot see correct ram info on both linux and u-boot.
I want to ask these questions:
- how can I set u-boot for 2 gb ram,
- and can I see 2 gb ram info over linux without configuring u-boot
- what is the point of u-boot ram configuration ( all ram initilization is in here? )?
