RAM memory map for uart load and TFTP boot

Gokul cg
Intellectual 420 points

Hi,

I am trying to load SPL and u-boot over UART . I could successfully load SPL and U-boot to RAM of the EVM and I am getting u-boot console .But I wanted to know from which location of the RAM both SPL and u-boot is running and which portion of the RAM currently in use.

After loading SPL and U-boot over UART, I want to load kernel and filesystem over TFTP. For that I should use some command like,

tftp <RAM address> uImage


For specifying this ram address properly ,I should know from which location of the RAM both SPL and u-boot is running and which portion of the RAM currently in use.After some trail and error , i know that "tftp 0x82000000 <kernel_image>" will work and ram location 0x82000000 is free to use.But i want correct memory lay out.


Please give some inputs.

Thanks
