RAM size configuration for IS43TR16512BL-125KBL

When you modify to 480MB does uboot and kernel works as expected?

ArtursArtamonovs  Did you have any idea about this?

Hi Denny,

Could you try changing the this parameter in the config file for SC598. This commit as an example, fixes the memory size for SC598 in the latest u-boot (Note that the variables are same).

Hi Utsav,

as the begin of thread show, I have tried to setting as picture.

Then I can get SDRAM size from 224 MB to 480MB.

But I can't config to get 992MB as SC594.

As mentioned above, I had previously suggested setting MEM_ISSI_8Gb_DDR3_800MHz instead . Just to confirm, have you coupled this change with the one just suggested? (essentially setting the same as SC594, which has the desired size)

I can get 256MiB by this configuration. How can I get 992MiB as SC594?

Could you change CONFIG_SYS_SDRAM_SIZE to 0x40000000? This should result in a size of 1024MB. If you particularly want 992MB, you could also try 0x3E000000 (same as here)

I have tried to change as 


and I get following issue. (uboot blocked at DRAM, and I Ctrl-C on gdb)

Could you also try setting these definitions on top of the changes as per sc594's configuration? (CONFIG_LOADADDR and CONFIG_DTBLOADADDR)

There is similar settings now.

Or you mean use same value as 594? 

If the current settings do not boot, I would suggest using the same values as sc594 since that configuration is known to work for the memory size.

patches I try to setup as SC594.

Still the same, I only can get 480M (0x1e000000), more will be hang as before.
